07/16/2009 NOW: OK/TX/KS/MO/AR/IL

Insane convection going up with the intense daytime heating over much of the central and southern Plains. Very impressive cell just north of OKC, now right on top of Norman! Looks like damaging winds are big threats with these cells, and note the OFBs clearly seen on radar!

Several counties all over the above-mentioned states now SVR T-STM Warned.

Should be some photogenic cells with amazing structure and CG displays!

Who wants to guess how many MCSs we get out of today's Plains action? I can see 4 strong areas of indication that these will quickly evolve into MCS mode...

1. TX and OK panhandles - racing SE into mid Oklahoma overnight
2. NW Texas - initiating near Childress area and racing down to Abilene overnight.
3. Already one ongoing in Arklatex region.
4. Fourth one ongoing (but appears to be weakening) over much of eastern/southeast Missouri.

Widespread flash flooding appears to be a threat to be cautious of during the late evening and overnight hours with these systems.

Is it just me, or does that cell near OUN appear to be taking on a hook appearance?
SRVs showing some big-time winds near Lake Thunderbird currently!
Two individual outflow boundaries now intersecting at the inflow of that lone KTLX cell !!!

Mods, can IL be added to this thread? The storm that went up a couple hours ago over the northern part of the STL area is now TOR-warned in Marion Co., IL. 73 dbz and hail marker in GR-Level3 indicating potential for 3-inch hail, too.

I got a couple pictures of this storm across Dunlap Lake earlier this evening as it passed just north of Edwardsville, producing nickel to quarter hail from Alton through Bethalto:
