4/6/10 REPORTS: IA / MO / KS / OK

Wasted 500 miles in Iowa after about 400 in and around Missouri the day before. That and a quarter billion hours watching models update for the two days ahead of time. Wow am I a freaking slow learner. The only thing that got me chasing on the 6th was, "What else is there to do today." I really wanted to sit out a few "decent" days so I could at least know I could, when I didn't expect them to pay off(read fast motions...grunge....which were both certainties). Aaarrgghh.

Never seems like a big deal to just go chase, until the chase is over and your 3 hours from home...on the days you knew better. Then it is like, damn it, I should have came up with anything else to do this day. The day itself isn't even that annoying, it's what these do to later days for me. I end up wanting to hedge my bets harder later on, after tossing away money and miles early on. Anymore I seriously just want to blow off a day I think looks great, just so I know that I can do it.

Anyway, couldn't have done the day much better(great at that on the days that don't matter). Waited on I80 near Malcom but didn't go north of the front, since that cold air was so damn close and things were heading for it so soon. Dropped south at first signs of stuff trying to go on Missouri border south of Des Moines. I then just made sure to stay ahead of things till they got better. This was a race now zig zagging back northeast. I shot north of Brooklyn just as that storm got organized(crossing the front), got a big hook and then tornado warning. Looked like a decent supecell to the west. Some mesonet and a few other chasers parked on a muddy road there and watched and it seemed this was all that was around then. Rather than stopping on that road I went a bit more north till I was just about in the path(my car fears anything wet that isn't paved is why I did not stop there). Lost sight for a second in core, so stopped and the view came back. I was like, hell yeah, timed this all perfect on this fast moving day. But no, it wasn't to be. Portion to the northeast bows out and the thing just turns to a pile of goo. Then it was like, well that was fun. I tried to stay with it for a while but it looked like a lost cause, speed-wise as well as just the storm was toast looking.

Lovely looking flooding all around there near Chelsea I think it was. Thought, yeah, lets get back to a more major highway soon, as the fields looked so damn full.

I wanted to get cored by big hail and couldn't even get that out of the storm up in there. The line was pathetic after that on I80, hardly any lightning. The mosquitoes were amazingly bad for early April, yikes. Must remember bug spray next chase. They were bad in nw MO the day before too.

I was surprised just how many semis were blown off I80 west of there and over how big of a distance(couple miles or so?). Saw one in the median but most of them were well off the north side. I wish I would have been there in that when that went down. Then the day might have been worth the chase. As it stands, I have 3 chases I should have known better on and 0 chases worth anything. And again, they don't bother me much as far as doing them. The totality just always has a way of making one think they can't afford better days later on(even if I chase those too anyway lol.....but yeah a day like June 5, 2009, which I didn't chase, in some ways doesn't happen because of these early stupid days...though that day itself had issues to cause some hesitation).

Very ready for a plains, slow moving, storm day. I will take a good lightning storm! What I most want to do, severely badly, is to just not chase some of these things. The ones that are "close enough" but you don't think will pay off in many ways, other than maybe a lucky fast moving tornado, which really seems unlikely on them as it is. Annoyed I was at the point I was ready to actually skip yesterday, but the ONLY thing that made me go was, "What else am I going to do today." I thought, it won't be annoying, it's too close to home anyway. LOL but come evening an hour east of Des Moines after racing around for nothing, I was like...damn it!

Those lead surface lows both days, veering things before another one forms/deepens later on to the west in KS, should have been big enough flags to sit out both days. Bad when the low level response looks like it's getting good 6 hours after darkness. And hell that's just one issue. Course the day you don't ignore some of the issues and hope for the best, something "crazy" happens.
 
Wichita area chase...no cigar

Opted to chase the KS target zone...to stick with my original forecast area. Rich and Ryan Thies (fresh off a small tornado capture the day before near Hillsboro IL) joined me for the chase. We were stymied like a lot of others when SPC dropped a SVR blue box over the target area. Signs of things to come. We headed down I-35 to EMP just as some hailers were moving in from the west. These looked like they were cold front storms/supercells....so we decided to head south after some discussion with Jeff P. The dryline-cold front union was near Wichita so we figured this would be a likely spot where the cap could be more easily breached and maybe some lower LCL's. As additional severe t-storm warnings kept getting issued, we finally found what looked to be tail end charlie nw of El Dorado where we stopped and watched things slowly back build towards the Wichita area. Soon we headed down that way...and reached Andover to watch things. A severe t-storm warning was issued for a rapidly developing supercell (tail end charlie) on the west and north side of Wichita. For a brief moment in time, there appeared to be some decent storm structure...until the colder west winds hit, and the supercell raced northeast leaving behind some killer outflow. Below is a picture of tail end charlie as it moved across the northern part of Wichita. This is looking west-northwest from Andover...with the hailcore to the right side of the picture below. Overall the first chase of 2010 was abit disappointing...the storms failed to move off the boundary. This kept them rapidly training over the cold outflow surface temps. and did not allow them to get eastward into fresher warm inflow. Shear was strong but cap was certainly a big monkey wrench for my chase #1. :rolleyes:

I like many had sat around in the sun on Monday, and had that bustola feeling. So Tuesday I saw the linear looking models and started to trudge the 6+ hours back home already knowing I had wasted that second day off for Tuesday. Then the voice popped into my head... you all know what it says. "You wont catch what you don't chase."
So, knowing I had no commitments until work on Wednesday, I stopped on I-70 near Concordia, MO at about 10AM to wait for the 1630 Outlook before I would write it off completely. After looking over the position of the surface low and warm front, and the eastern Iowa wind barbs shifting from SW to SSW to S, and even a few with the ever so slight backing, I went to the Des Moins WFO page to see what they had to say and their HWO and media briefing was more promising. Just after reading that, the 1630 came in and the 10% was back with just enough enticement wording to drag me north. I Started the trek North at 11:45AM and really didn't stop more than a few minutes anywhere from then until I got home at 3:30AM.

By the time I got close to I-80, the cells south of me almost lured me back to watch them, but the road system south of I-80 were annoying enough to get through the first time, and with these storm motions, I wanted to get to the area near Cedar Rapids, as it was in the region with the few sites showing backed winds where the boundary could get before dark. When I got West of Marengo, I could see they were indeed slightly backed. Then the cells to the south dragged the more E-W oriented portion of the boundary away from the leading northern segment, and the more discreet tornado warned supercell blew up north of I-80. I did finally get some good video when I was just south of Shellsburg, IA at about 6:55 PM, even if it just barely wasn't quite a Tornado.

Here is a link to the 8x speed video of the cell interacting with the boundary and rotating nicely.

I gave up trying to follow the cell North of Cedar Rapids IA as it was getting dark. Then, like most other IL chasers blasted south to I-80 to get out in front of the line and started my 8 hour trek home to get 3 hours of sleep and go to work.
 
Here's a 16x timelapse of my chase near Malcom, IA shot with the robotic camera dome. The beginning shows bubbling convection as we waited for the newly formed storms to our southwest to strengthen and race up to meet us. We get a few peaks at a rain shrouded wall cloud, and then one last look at an outflow dominant base before we lost the storm at the Cedar River.

After chasing across Western parts of Southeast Kansas for most of the day, Storm Chaser Austin Marti, and I decided to head Northeast between the Thayer, KS and Chanute, KS area to get some footage of storms building up rapidly in Wilson County, KS. The storms moved into Woodson County, KS to our North later on. We really wanted to get some amazing lightning footage to end our day which would of been a bust if not for the incredible storms building into the night.

After a long day of driving and seeing nothing we did not give up on the severe weather potential that was there for that day. It just did not happen until late in the day because the cap was preventing the storms from forming.

Also ended up chasing the eastern Iowa cell that tracked northeast to the Cedar Rapids error. Made the mistake of trying to meet it south of 80 and played catchup the rest of the way. Did get blazing sirens and a wall-cloud -- perhaps -- for a bit around the city. Beforethat was on the big elevated hailer that went north to Waterloo. (but like others dropped off once we saw it *seemed* to be crossing the warm-front . . . may have just rode it, though)

Despite initial optimism with the instability and speed of shear we were working with, the day basically unfolded how I would have predicted the night before looking at model runs. Shear at lower levels was too veered... too linear a storm-mode. (not even resorting to two good-luck bandanas could save this day)

Nice to bump into Skip and a few other chasers whose names I have forgotten.
(I'm envious of Skip's video-dome thingy)
