Well today me and my mother chased the storms produced by the mid- upper level low in South Louisiana.

One storm produced a fairly decent wall cloud:

Here's a few shots I grabbed from the TOR warned storm in Ray County, MO this evening (near Elmira). Sorry about the quality as this was an unexpected chase. Only had the cell phone available.

Didn't have to go too far to get this. Shot this time lapse of a developing severe thunderstorm pretty close to home. This storm dropped near 2" diameter hail and 60mph winds about 30 miles south of where I shot this.

Excellent chase day minus a tornado, but what are you going to do on a day with such meager low level shear.

Chased the initial Illinois supercell from north of Macomb down to Lewistown before bailing back west for a structure show near Astoria, IL. Chased that one down to the Illinois river before it died, and we ran out of road options due to a big body of water.

Not bad for a nice summer NW flow event... it's been a while in these parts!

Found a couple already partially melted 2" hailstones after the big hailer near Havana moved through during the evening.

I chased the late afternoon storms in west central Illinois today. After waiting briefly in Monmonth, IL for storms to fire, I dropped a bit back south on US 67 to catch the most promising of several discrete cells that shot up just east of the Mississippi River. I intercepted this storm near Rariton, IL, and then chased it east as it began to get its act together near Walnut Grove, IL. Several wall clouds were reported and the cell was briefly TOR-warned around this time.

I let this storm go a bit north of Bushnell, IL in order to drop south and then west on US 136 to catch another cell that was passing over Macomb, IL. It didn't do much, but it looked pretty good as it moved off to the southeast. I flanked it to the south for a while before letting it go around Vermont, IL.

The first two photographs are of the Walnut Grove storm and look due east. The second two photographs are of the Macomb cell; I'm on US 136 here looking west.

No crowds, a good road network, and I ended up less than two hours from home. A good, fun day!

Yesterday went as expected – I think for everyone. Tornado chances were pretty slim. However, I certainly enjoyed it. It was a treat to see primarily discreet storms. I get out so infrequently I appreciated the practice of targeting and maneuvering around the storms.

I stayed to the N, in Lee, Bureau and LaSalle counties at what appeared to be the most nrn extent of Cb development. Did see the backside of the Fulton Co storm(s). Storms went up pretty quickly, had nice structure and the lighting was great.

(Not sure how to attached photos - sorry.)

Saw rapidly rotating rising scud below storm near Lisbon, Il. Our view was blocked but was very close to being on the ground. Another one of those close to producing storms-but it tryed hard.

jpersonette,

I'm assuming you were looking at the warned storm first noted near Newark around, what 4:30? Actually saw the back end of that as I was heading S on IL251 just W of I39. Thought about going after it as it did have a wall cloud/inflow lowering on the back side. Decided to bag it tho as it was too far away.

I actually had some rotating scud tags being ingested into one of the storms I saw. Lasted about 45sec. Still fun, tho

FWIW I did find a host for some of the photos I took yesterday. Nothing dramatic, just deep moist convection:

I targeted WC IL but chose to stay on the E side of the IL river. For the first cell of the day this was no big deal as I was late in catching it though as shown in the first two images, it wasn't a complete loss. For the second and third storms I should have continued W but didn't and as result, both cells pretty much died upon passing Havana. Still a good day topped off with a spectacular sunset on a cell over SE IA that was tornado warned.

Was with Pritchard most of the day, so many of my shots will be similar. Short story, since it's late (and I've been processing shots from this day for a little while, still trying to alleviate Saturday's pain), was on the first storm to go supercellular in IL from its earliest stages. Watched it form, lose, reform, lose, and reform beefy wall clouds in its classic stage before a gradual transition to sculpted HP (no photos quite yet of that evolution, but I do have some yet to process).

Tornado warning was issued for it for a little while shortly after our report (about 3 W of Bushnell or 5 NE MQB, I think) on the wall cloud as it began pulling scud up pretty hardcore and a small RFD cut came in from the WSW, about half an hour before it transitioned. After debating, we made the call to drop back west to a trailing cell that was more isolated and showed a more classic appearance on radar.

5-year structure. Beat anything I've seen come out of the Northern Plains structure-wise, and photos don't do it justice. But I tried my best. 'Course, I may come up with something better as the processing continues.

After it, too, wrapped up big time with a textbook hook (only to be foiled by new crapvection to its immediate south) and began to lose intensity, we let the cell go near Bluff City along the Illinois River near the Fulton/Schuyler County line. But as we went northeast toward Havana, we found a new elevated supercell with a strong updraft (indicated >3" hail on GR) that attempted to become surface-based and form a wall cloud right before our eyes.

We narrowly missed the core and saw an interesting show about 1/2 mile out over the waters of Emiquon NWR, and then stopped about a mile up 78 where hail had covered the road. We found mostly quarters and half dollars, but the stone in Drew's photo above measured very close to 2" in diameter, so it's not unfathomable to think that there were others out there as well.

A great day before the day; I was on top of the world after this day. But Mother Nature has a funny way of keeping us humble, as I learned the next day.

I chased in Michigan this day on the 'little cell that could'. It generally looked like crap when I first got on it, but produced a nice rotating wall cloud and tracked through Lansing causing plenty of downburst damage in the north end and into East Lansing.

I posted a chase report & videos at http://www.benholcomb.com/Chase-Accounts/20100604
