Need to keep an eye on the Des Moines, IA area. RUC data suggests super cells and a risk of tornadoes near the boundary with decent low level shear as well.

Some days ago i had an awesome stream from Des Moines IA. Any ideas ?

A whole rash of tornadoes now coming out isn't there Dave, how far away is the cell now you were watching BTW, over you yet?

Also I think if things carry on like this there could be justification for an upgrade to moderate. Still 50-50 IMO though for that.

KWT Pick it up from here..that last warning is for the counties to my west..out 50 miles and closing. I'll be off here for awhile.

[srainhoutx]

Cap is eroding quickly now. CU field increasing in NW MO as well. Don't know if SPC will go Moderate, but things are about to start popping along the boundary. Dave, that cell near INDY looks suspect. Looks like your part of the world is about to get active and fast.

[KWT]

Keep safe, though if possible could anyone else do this thread, since there are other severe storms in places like Portland which I'm covering also in the other thread!

Yeah things really are kicking off now, the cap is eroding, giving thats occuring widespread now I think they may well at least be tempted to upgrade...

[srainhoutx]

Another 45 minutes or so KWT and I'll be finished for the day. Perhaps we can keep this thread for tornado warnings and the other for Severe T Storms? Active night ahead folks.

[KWT]

Yeah thats what I've been thinking, since there are a LOAD of warnings for severe thunderstorms, don't want this thread to get cluttered really!

[Bunkertor]

Cap is eroding quickly now.

What makes you think so ? The SVR Warnings popping in Dave-Land ?

[srainhoutx]

Cap is eroding quickly now.

What makes you think so ? The SVR Warnings popping in Dave-Land ?

Looking at 700mb temps and thermal ridging it could go either way and is more than likely part of the reason the SPC did not upgrade to Moderate IMHO. Keep an eye on NE KS the next hour or so. If we start seeing development, then it may be off to the races so to speak.

10 ° difference between 700 and 850 mb by 0z. There is some stuff in place, but I rise and say "No"

CONCERNING...TORNADO WATCH 49...50...

VALID 052247Z - 052345Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 49...50...CONTINUES.

...SEVERE THREAT HAS SPREAD A BIT EAST OF WW50. COUNTIES MAY NEED
TO BE ADDED TO ACCOUNT FOR THIS DEVELOPMENT...

LATEST WV IMAGERY SUGGESTS SHORTWAVE RIDGING IS OVERSPREADING MUCH
OF ERN MO/SRN IL. RADAR DATA SUPPORTS THIS PER RAPID DEMISE OF
SUPERCELL OVER MONTGOMERY/SHELBY COUNTY IN CNTRL IL. OTHER MORE
NUMEROUS SEVERE THUNDERSTORMS HAVE CLUSTERED ALONG AN AXIS FROM
ECNTRL IL...SEWD ACROSS CNTRL IND INTO NRN KY. THIS ACTIVITY
APPEARS TO BE STRONGLY TIED TO RETREATING WARM FRONT AND SUSTAINED
LOW LEVEL WARM ADVECTION IS LIKELY TO AID THESE UPDRAFTS FOR THE
NEXT SEVERAL HOURS. GIVEN THAT DEEP LAYER AND FAVORABLE LOW LEVEL
SHEAR WILL REMAIN SUPPORTIVE OF SUPERCELL ACTIVITY THERE REMAINS A
DISTINCT POSSIBILITY FOR ISOLATED TORNADOES. WEAK SUBSIDENCE SHOULD
GRADUALLY OVERSPREAD THE REMAINDER OF WW49 FORCING THE BULK OF
STRONGER UPDRAFTS INTO THE OH VALLEY.
