4/22/04 RPTS: TX/OK/AR/MO

Well what a dissapointing day on my end. I was initially in Davis, saw JR
Henly (I'm pretty sure that was you) jetting south on I-35. I stayed in Davis for a few more, tried to gather some info and decided to stick with my plan to target the 15% tornado potential as outlined by the SPC. To make a long story short, nothing but weak severe storms in-and-around Ada. I had a cell phone problem which held me up from going anywhere else for an hour and a half. And by then I had ran out of usable daylight. So I had Tornadic Supercells on each side of me (by about 100 miles, but who's counting), and I screwed up. No lightning show from the weak storms to boot. So as I head off to bed here in Ada at my brothers apartment, I am hoping I can rebound tommorow out west.
 
I had originally planned to blow off today, but I ended up chasing anyway. After watching towering CU bubble along the dryline all afternoon in NW TX, a storm finally fired in SE Clay County. I made a quick call to Steve Miller to let him know about it (as far as I knew, he was sitting in Ardmore), and the first thing he said when he picked up the phone was, "Jeff, I know about it...I'm blasting west on Hwy. 82." Once he told me how nice the storm looked from his vantage point, I grabbed my gear, hopped in the Jeep, and raced northwest on 287 out of Fort Worth.

The first SVR for Montague County was issued as I was gassing up in Decatur, giving a storm motion to the ENE at about 25 mph. I could already tell visually that the storm was sitting stationary, backbuilding to the WSW, so I just continued up 287 to Bowie rather than make any move to get out in front of it. Just a few miles south of Bowie, the updraft base came into view...with a giant, ground-dragging wall cloud underneath. This thing was SCARY.

I jumped off 287 and dove into Bowie, racing the wall cloud to the intersection with Hwy. 59. From there, I went NE, the wall cloud right over my left shoulder, still dragging the ground. Unfortunately, I don't have any photos from that point, as I was too busy driving - the inflow was intense enough to require keeping both hands on the wheel, and I was busy dodging traffic.

Steve Miller and Robert Hall passed me going the other way as I started to get into precip, so I pulled a U-turn and fell in behind (Steve was running GPS, whereas I wasn't...and past experience has taught me that the Roads of Texas is less than accurate in Montague County). We stopped on a farm road just SE of Bowie to watch the storm try to wrap up, producing a decent rotating wall cloud. But just as things got interesting, cold, wet RFD came blasting in. It was yesterday all over again.

The storm seemed to be making a pretty hard right turn by that point, so we dropped south on a collection of dirt and paved roads to just NW of Forestburg. Along the way, we realized the storm had some incredible structure: big, stacked plate, mothership meso. It's a shame we were too close to photograph it.

On FM 455, just NW of Forestburg, we watched the storm produce another wall cloud (of sorts), this time more vertically oriented. The rotation was relatively vigorous with this feature, but once again, just as it tightened up, cold, wet RFD arrived. So, we dropped down to Forestburg to assess the situation. The storm still had some nice structure, but had taken on a linear HP look - it was also about this time I first realized the storm was truly sitting stationary. We could see a newer storm going up to the west, and with ours looking like it wasn't going to put on much of a show, we headed west to Sunset for a closer look.

The newer storm was producing a wall cloud of its own, but...well, you can probably guess what happened by now.

It had become obvious by that point that the tornado potential with the storms was nil, and with everything starting to line up in an HP mess, I opted to jump back on 287 and wander south in search of some good structure shots (that, and it was in the direction of home). Made it home around 8:00 PM, only to check radar and see that the storms were STILL sitting in the same place. Ran to the post office, got back, checked radar, and saw that the storms were STILL sitting in the same place. Browsed through my photos, ate dinner, made a couple of phone calls, checked radar, and saw that the storms were - you guessed it - STILL sitting in the same place. It'll be interesting to see just how much rain fell in and around Bowie, seeing as they had an HP supercell of some sort sitting overhead for 4-5 hours.

Not a bad chase. It was nice to see a big honkin' supercell south of the Red River again (a rarity in recent years), and the drive was short.
 
I was heading to hwy 75 and I-40 but decided to stick around south Tulsa since storms looked to be firing here.Went east at 151st and hwy 75 and proceeded to Bixby and went south of the Arkansas River. Headed east on 64 . Ended up going to Haskell so I could head back north since my sister lives close to where the Tulsa tornado hit . Luckily it wasn't so I went from there back to Bixby to watch the one moving in there. After it was moving on east and I wanted to get away from the parking lots being created along 64.and winded my way to the one south of Bixby at that time. Followed it to the east side of Muskogee. Heard the one out of Henryetta was strong so I headed for it by the time I got to Checotah it was off to the west and dying. Decide to get a mickeyD's at the WalMart drive thru but was told everyone was in the bathrooms because of the tornado warning. The Manager was in the parking lot looking north I pointed it out in the west for her and went down the street for a pack of donuts instead.
Chased 3.5 cells , 3 of them had funnels off and on (South Tulsa, Bixby and the one that went into Haskell then Muskogee)
I saw nothing I could actually say touched the ground, so no tornadoes for me, again
Pic's by tomorow and video in a day or so.

I did have 3 vans pull into one of my shots then they procceded to pull in a private drive and set up cameras right across the hwy in front of me . Havn't decided if I will post those pics yet. The crowds out today already got negative media reaction today we don't need this kind of thing to add to it.
 
didnt get to chase, but friends of mine said the storms were cool, saw some video, neato.

decent rotating wall cloud. But just as things got interesting, cold, wet RFD came blasting in. It was yesterday all over again.

Whats a rotating wall cloud? doesnt a wall cloud HAVE TO BE rotating to be called a wall cloud? thats like saying, hey, theres a rotating mesocyclone.
 
Actually, a wall cloud does NOT have to rotate to be considered a "wall cloud". A wall cloud can consist of any organized lowering from the base of a thunderstorm. Although rotation often takes place when this happens, it is not a mandatory feature.

Nope. Technically, a wall cloud is just a lowering underneath the updraft base. It doesn't have to rotate.

EDIT: Lance beat me to it.
 
Brief overview. No tornadoes.

Got on a nice LP storm near Castle. Heard about the tulsa tornadoes at this time but decided to stick with our storm. Did for a bit, but delorme maps let us down and we got temporarily lost in the middle of the core and okfuskee county. to make matters worse, our planned route was detoured and we got an extremely long scenic route around Lake Okmulgee. Finally got east of town and rejoined on the Muskogee supercell. Followed it from somewhere around Haskall to Muskogee... somehow we missed the tornado. What a madhouse!!! people everywhere! mostly locals it appeared.

Some good CG here in Norman right now -- that's about all I saw today as I ran outside to the Tahoe to roll up the windows I forgot I had left down.
 
Just wondering if anyone had noticed the TREMENDOUS doppler estimated rainfall in/around Montague county Texas since this afternoon. Supposedly over 13 inches as of midnight central with another storm currently taking aim on the waterlogged area again!
 
Tulsa area tornadoes

The first cell in NE Oklahoma formed directly under the surface low. Ir began rotating as a small shower over south Tulsa, then dropping 1 inch hail in Broken Arrow. Tree and roof damage was reported in NE Broken Arrow from a brief spin up, and then Tulsa NWS issued a TOR. The tornado later touched down several times south of Inola and south of Choteau. It looked it was about 100 yards wide at times, but did little damage through the countryside east of Tulsa and Broken Arrow. Charles Allison captured a 5 minute tornado life cycle near Haskell, OK, and his video is being shown on the Weather Channel.
 
I actually liked the setup today more than yesterday. After review model data, decided to play the boundaries up between I-40 and I-44 east and northeast of OKC. Left Norman about 3p, and heard that a storm was going up north of Tulsa. Got to Henryetta, and proceeded to head north on 75. I liked a storm to out west, but the storms south of Tulsa, and north of us, were severe with rotation. Hearing persistant reports of a large and damaging tornado in and around Rogers County, briefly thought to try and catch up to that storm. However, the storm in Okmulgee county went tornado-warned as we neared west of Bixby. So, we shot east on 171st and then south of hwy 64. Drove through some very heavy rain, but emerged near Haskell and watched a very nice wallcloud try to do something. The main one seemed to get undercut, as a new wallcoud formed a little to east south and east. Headed back on 64, where we saw a tornado looking west out of Haskel. It had nice cloud-to-ground condensation, but was relatively short-lived. I reported it to WX5TUL, but it didn't last long enough for me to get a picture or vid of it. Gabe Garfield, however, was able to get some of it on video...

Caught hwy 62 and headed east a little, periodically stopping to watch wallclouds and attempts at tornadogenesis. It looked quite promising for a while between Jamesville, through Taft, and up to Muskogee. As we neared Muskogee, we began to see evidence of a strong RFD punch developing, as scud was pushing rapidly southeastward just to the south of the meso. Non-coincidentally, rotation started to tighten up and again attempt to do something. Now, here is the grey part....

Looking north from Muskogee, we saw a narrow area where condensation in the shape of a tornado was touching the ground, and it had some rotation as well as strong upward motion. However, the rotation was quite weak. The pseudo-nado lifted, but 'touched down' again near the same area a few minutes later. I still don't know what to really call this ([url]www.tornadocentral.com/now/pseudonado.jpg]...[/url] Whatever the case, we went south a little in Muskogee to ensure safety, but later went back north and then east on 64 out of Muskogee. As darkness was falling, the storm appeared to lose some of its supercell characteristics. Could be wrong, but that's just what it looked like from our perspective. So, we called it a day and headed back to OUN.

All in all, it was a good day. Slightly disappointing to again have a nice supercell with numerous wallclouds that only produced brief, weak tornadoes. However, can't complain with 1 for sure and possibly another tornado. Whatever the case, I was happy that my target verified well.

Obviously New Math is no substitute for chase experience......


Now, onto the disaster......

Mickey Ptak, Jo Radel, and myself convoyed with Chad Lawson and Susan Walling. My thought was to go east and stay ahead of the boundary, so we left OUN around 2:30pm on OK9, with the intention of driving east until we had backed surface winds (or at least due south winds). I had been debating between using 40 or hwy 9, the latter of which was obviously our choice.

Stopped in Wetumka and made a call to Dwain. he said the only storm was a cell near Tulsa that was right on the boundary moving northeast. We both assumed the storm would cross the boundary and elevate....big mistake. By the time we realized the craziness going on east of Tulsa, we were still west of McAlester with no choice but to continue east until we hit the Indian Nation Turnpike.

Long story short, we missed all the Tulsa stuff, and missed the Haskell tornado by 10 minutes. The tornado reported west of Muskogee at 7:15pm was bogus, IMO. We were all over that storm from 6:20pm through 7:30pm and at the time of this reported tornado there were cool west winds and the entire base was surging east on outflow winds. The road in that area at that time was lined with emergency manager/spotter/volunteer FD folks, so I'm highly skeptical of any tornado in that area at that time. Gene Moore was parked not 100 yards east of us, and he left during this time.

Then we heard a tornado warning issued on the storm because of a media-reported tornado at 7:35pm 3 NW of Muskogee, which again, we were looking right at and saw nothing but outflow scud (winds were cool from the west the entire time west of/into Muskogee. I don't see how any tornado was possible.

Ran into Hank Baker south of Taft earlier (around 6:50pm), and he reported having seen a nice stovepipe tornado west of Haskell (the one we missed). From about 6:40-6:50pm, the storm wrapped up hard near Taft and (once again) we were certain it would produce a tornado....but no.

So yet another day goes by this week and tornadoes have still eluded us. Tomorrow is the last chance for a while, so I'm gonna lick my wounds, get some sleep, and get after it again tomorrow with the hopes of finally breaking this horrid April curse.

I am sorry but wasn't this the same person that was doing is own predictions and issuing his own outlooks and doesn't know there are non-rotating wall clouds? :shock:

LOTS of wall clouds do NOT rotate.
 
Two tornadoes today...one near Haskell, Oklahoma and one west of Muskogee.

Short chase sum is up (not really a chase sum) on my website. Most importantly, pics are up.

Gabe I am sure glad you posted that pic of the tornado west of Muskogee. We saw that as well for just split second before trees, once again, got in our way. So Shane we did see a tornado. Shane was pissed. Two chases in a row and no tornado. Correction! One chase now with no tornado.

I watched my video of this last night, I guess I'll watch it again....we were all over this the entire time from Taft through Muskogee, and after the storm wrapped up near Taft (6:40-6:50pm) then occluded, it stayed outflow dominant throughout the duration north of and eventually east of Muskogee. Our winds were constantly from the west and were cool; the southern end of the lowering began to form a shelf cloud as outflow began pushing it east, a few miles west of Muskogee.

All I can figure is, this thing occured while we were driving north and blinded by trees/low valley. I just didn't see anything that looked to be rotating after the Taft area occlusion.

No one has included time stamps with these reports...could someone please provide an exact time/location? I've got video from west of Muskogee at 7:17pm showing nothing but outflow scud, same thing at 7:22pm and 7:35pm. I dunno, if someone could tell me exactly when and where this was supposed to be it would help.....I saw about a million dangly things west of Muskogee that looked exactly like the reported tornado, none of which (to me) appeared to be rotating, other than outflow shear.

Not saying it wasn't there, I just need someone to tell me precisely when/where so I can review video objectively.
 
Here are some distant pics from the N. Texas monster. This storm went from a supercell w/ tornado warning (near Bowie) at around 11z to a massive, back-building, HP multicell an hour later. It dumped 4-9" of rain in SW Montague and southern Clay counties. I took thses pics in Burkburnett, an hour's drive NW of the storm.

crappy day

Well this was my 4th day in a row chasing and was kinda crappy. I started out heading east on hwy 9 from Norman around 2pm. Expecting to stay in front of the surface boundary. I then headed south towards Ada, stopped in Ada and downloaded some data just in time to see the Tulsa stuff. Kicking myself in the butt for going south I stuck to my guns and got on some storms around here. I followed a couple that passed though Pauls Valley never able to stay at the S side of the storm b/c more cells kept coming up from my SW. Finally waited and saw that a break in the S. development so I hopped on the southern most cell, near Pauls Valley. It looked promising for development for a while but quickly fizzled out.

Oh well what can you do, ya win some ya loose some. I am sitting today out b/c it's gonna be just about like yesterday w/lots of cells going up right on top of each other. And I have had enough for one week, never thought I'd say that....
 
Brief:

Drove overnight/pre-dawn hours from Kalamazoo, Michigan to eastern Oklahoma, dropped south of Tulsa upon arriving (with little to no sleep) around 2pm and viewed cb'O'genesis occur to my southwest/overhead. Watched/shot video/slides of the Broken Arrow cell from birth until tornado genesis before dropping south to intercept the next SUP down the line near Bixby/Leonard. Waited and waited for tornado genesis before dropping S again (now meeting up with Tim Jones and his friend Chris). At Haskel; we dropped southwest of town and got up close and personal to the intensifying meso/wall cloud. Apx. 1/2 mile from our location, observed a picturesque tornado just to our SW for about three-five minutes. (See report below).. eventually getting within 100 yards from it (too close for comfort). Eventually dropped S to the next cell, then headed E on I-40 towards Muskogee around sunset. What a show; my only complaint was that I had no chase partner (thus created navigation problems here and there).

Full:

I still haven't had a chance to write up *last* weekends chase; so I'll sum that up here. Broke my long standing Iowa curse on Saturday, April 17 with a high-based tornado warned supercell W of Mason City. Spectacular lightning display, marble hail to the eye -- it was great... and in Iowa! Stayed overnight in Albert Lea Saturday; with more convective debauchery transpiring after dark (arriving to tornado sirens in Albert Lea). Chased north of the Twin Cities Sunday; numerous high-based SUPs that went TOR warned but didn't produce. Back for exams on Monday; chased the unexpected IL/IN outbreak Tuesday, exams all day Wednesday... then after a 1 hour nap, departed Kalamazoo for Oklahoma Thursday morning at 1:30am ET.

Wednesday (in-between exams) was a mad-scramble to get Thursday-Friday off from work and round up a chase partner(s). No luck with the later; everyone, except a tempted Jim Leonard, was able to chase. Unfortunately sky rocketing air fares and the last minute nature of departure prevented Jim from flying into OKC. Okay, no partner -- except the potential of meeting up with one on the road later... alas, departed Kalamazoo (as previously noted) around 1:30am. Reached Litchfield, IL by dawn, where I was forced to pull off and get a one hour nap in. Carried on, grabbing some sickly Burger King from breakfast and continued the haul across Misery.. ahem, southern Missouri.

Keeping myself awake by doing Roger Hill laughing impressions/other tomfoolery, continued the drive; stopping for stretch breaks here and there before entering NE. Oklahoma. Was informed of an MD from one of the two Chris's nowcasting for me (Novy or Gullikson), which highlighted my target region of Pauls Valley to Seminole. Still pressing on thru the strat'o'soup, finally broke out of it at Tulsa. Thru the widespread Strato/fracto CU, noted towering CBs to my S/SW. I dropped S on HW75 and sat at Glenpool; watching (what would be) the Broken Arrow/Tulsa tornadic supercell approch my location from the SW. Another base developed overhead (will have to go back on the video log and see if *this* was the developing Broken Arrow cell), and moved slowly NE at 15. Received a call from Jim Leonard, informing me of better CAPE and instability to the S... yet, the dilemma was blow off the developing Broken Aarow cell (which looked to be getting it's act together visually) and head S; or stick with these first cells in the backed E/SE winds. After some harsh debate and tasty beef jerky, I decided to commit to the Broken Aarow storm.

Dropped S to HW67 taking that E to Bixby; before heading N on 64/169 into the bussling town of Broken Aarow. The meso which was broad to begin with really started getting it's act together just to my E/NE. Driving E on 101st/New Orleans St., the wall cloud rapidly intensified and tornadogenesis occured. I was unable to view this as trees/buildings/school buses obscured my view... in fact the only way I knew a tornado was on the ground was from the frantic sounding spotter on Channel 8 (KTUL?) screaming "TORNADO ON THE GROUND!!!" several times on live TV. Lots of traffic, but attempted to get E as quickly as possible. Wall cloud was in view as I eventually intersected with EW69 (was New Orleans St.) and HW51. 51 took me on an E/SE jaunt, before I choose a random "local road" (heading E then N). Tripoded and shot stills/video of the large meso/possible tornado (low contrast) to my N. Became bamboozled with Joe Sixpack local yokels before packing up and dropping S to the next cell down the line near Bixby.

I had visual on the new storm/base to my W/SW; thus backtracked and headed W on "local road" (EW71 RD???) towards the new meso/wall cloud. Wish I had a chainsaw while on chase, but eventually found a good spot on the Tulsa/Wagoner Co. line. Tripoded and let the meso move E towards me. Wearing sandals, I proceeded to sink/get briefly stuck in apx. 1 ft of mud.. nearly loosing my once clean (yet smelly) Ralph Lauren sandals. Allowed the meso to get just overhead before darting/backtracking back E on "local road". The meso/wall cloud really began to wrap up and tornadogenesis was once again imminent. The road dead ended, but fortunatly had a S option (NS 414 RD)directly to Coweta. Sirens blared in Coweta as a new meso developed to my SW. Tripoded and let this come at me; before shooting E on the convient HW51 towards Wagoner.

Met up with Tim Jones and his friend Chris; whom had real-time radar/GPS in their vehicles. Being that I was working with "Roads of" like the old fasion, budget savy (just call me cheap) chaser I am; decided to caravan with Tim/Chris through the jungles. Dropped south to a new and promising SUP near Haskell. Meso/wall cloud structure looked nice while heading S on HW64; then W on "local road" (???). Passed TAMU team and a few others before heading S on another "local road" just prior to tornadogenesis, Tim and Chris continued S into the trees (why???) as I stopped and videotaped the tornado less than 1/2 mile to my SW (moving E). Tripoded, but didn't shoot any stills (darn); then decided to get a bit "Pitrowski'esque" and head S towards it. Now, this was very foolish, as I lost visual of the tornado momentarily as I headed into the trees (just to the N of its eastward moving path). Tim and Chris were just to my S; and fortunatly were stopped by a flooded roadway. I peaked the hill just in time to see debris pass within 100 yards of Chris/Tim (300 from my location) before turning around and getting out of there.

Blated N and noticed multi-vortex action (or was this my imagination) -- before backtracking and pulling off on the E-W road. Wow... I was estatic at this moment. Okay, this post is long enough... sooo... summing up. Stayed with the Haskell storm and encountered a plethora of chasers, locals, and little children runing rampant across HW62 near Jamesville before stopping off E-W HW 64/62/16. Tripoded and shot slides of the meso as it was phasing; yet Tim, Chris and I all agreed to commit to the storm just to our S. Headed back W and dropped S on HW62/72. Stopped again briefly as the base of the Haskell storm lowered to a bowl (did another tornado occur???). Continued S and got slammed by wrapping precip/hail. Called off chase after following the cell to Muskogee.

Ok --- Red box just went up W/SW of here; so Gary Wellman, Melissa Moon, and I need to get on the road.

*MANY* thanks to Chris Gullikson, Jim Leonard, and Chris Novy for the helpful forecasts/nowcasts while chasing Thursday!

Departing Norman shortly.

Interesting day to say the least. After targeting an area just East of OKC, we made our way up to Tulsa/Broken Arrow and just caught the tail-end of the first tornado. Having issues with the roads and river, we decided to let this cell go and proceed to the next one which was moving up from the Southwest (which turned out to be a mistake b/c it produced a reported 8 mile track further to the East of Tulsa).

Working down the line, I encountered another well-developed supercell with weak rotating wall cloud near the New Tulsa area, in which I never witnessed a funnel as several reports indicated. Lacking persistent rotation and any visible RFD wrapping, I proceeded to let that cell go and moved to the next on moving in over Coweta. Here, I met up with Blake Naftell who joined up with chase partner, Chris and I as we proceeded SW to the Haskell storm.

Approaching the town of Haskell, the cell was then tornado warned by NWS Tulsa and evidence of this was shown by the town siren blaring and locals standing in their front yards staring at the sky in the wrong direction. Having proceeded a few miles to the SW of town, we noticed a somewhat rain-obscured funnel developing as we attempted to find some a decent vantage point amidst the trees, trees and more trees. Having stopped briefly on a South road so Blake could tripod, being the front vehicle, I proceeded a bit further South (about 1/8 mile) to a spot that I thought contained a clearing. As I did this, a nice elephant trunk tornado developed about a mile to the WSW and quickly became wrain wrapped from my vantage point.

From this point, Chris came upon me while Blake stayed back for tripod video. Having a bad vantage point in the trees, we made the decision to proceed further south about 1/2 to the next East road to get back to HWY 64. During this, our road was blocked with several feet of water which made the road impassable and, thus, caused us to do a 12 point turn around. At this time, as we proceeded back to the North, the apparent tornado was just to our West - about 1/8 mile moving toward us. Debris was obviously visible with pieces of tin and other matter circulating near the ground. After proceeding at an accelerated pace back to the North, we became clear of the tornado and its weakening circulation about 1/8 mile up the road. Looking back to the South, no tornado at this time was visible.

Having let this cell go after some observation further to the SE, we made the decision to proceed down the line and catch the Henryetta cell. Although it featured a nice meso and wall cloud at its inception around I-44 and Henryetta, it quickly became jagged and lost any features of rotation and organization. I believe this was the time that the SPC issued a statement that the environment had modified to the point to limit any further chances of supercells.

Overall, a great chase day and better than expected considering the terrain. Funnels: 2, Tornadoes: 2, Trees: 100,000,000,000, Teeth: 13, Rivers/Lakes/Etc.: 375.

Departed Little Rock, AR by mid-morning and targeted areas of East Central OK. By 4pm, an explosive tower developed near Beggs, OK. Taking an east road near Mounds, baseball sized hail was observed near the intersection of N4000 and E0830. Pushing out of the hail and bumping east, a well organized vault and tail cloud came into view. Inflow was quite strong with excellent motion associated with the tail. Continuing east to Haskell, we dropped south on Hwy 72 and noticed a rapidly condensing funnel as the RFD precipitation wrapped around the storm. Shortly after, a stretched out tube touched down and then became more vertical and larger with time. The tornado reached its maturity as an elephant trunk tornado 3 miles WSW of Haskell. We continued to follow the storm and observed good rotation and structure. We ended the day just after sunset east of Fort Gibson.

Tornado first touches down 3 WSW Haskell, OK...

Late report from Thursday. Was on call at the hospital 8am Thursday - 8 am Friday but used afternoon meetings as an excuse to get out for a while. Meetings ended at 4:15 just in time to hear of the TOR-warned cell that had already produced in Broken Arrow.

Hustled east on 412 past Inola while hearing scattered reports of touchdowns per Tulsa Channel 6. At times could see the wall cloud southeast of me, but precip often obscured my view. Finally reached HWY 69 and exited just as the wall cloud was directly south. Stopped for gas at Love's, but they had all pumps shut off. Fortuitously, I was under the canopy while nickel- to quarter-sized hail pounded down.

Hail stopped and I got back on 69 going south. Traveled less than a mile, saw tornadogenesis a mile or so east of 69 (between Chouteau and Mazie). Beautiful tornado (you may have seen video shot by Channel 6), with a second area of rotation further south (never saw a touchdown). Lasted several minutes, then lifted.

Debated trying to follow this storm, but lack of roads crossing Ft. Gibson Lake made this suboptimal. Also debated dropping south on HWY 69 to the Haskell supercell. Unfortunately, I had to get back to the hospital before I was missed, so I peeled off the chase at 5:45. Boy was that hard to do!

Overall, a disappointing week compared to expectations. However, I did chalk up tornadoes on Tuesday (nighttime power flashes few miles NE of Lynn Lane and BA Expwy later confirmed as tornado) and Thursday (above). And saw supercells with wall clouds each day Tues-Thurs. So really no complaints. Wish I could have chased Friday, but 30 straight hours of no sleep precluded a 3-hr drive on a less-than-certain day.

Let the moisture return begin!
