doesn't look like we will get anything for the rest of the day in severe form.
based on spc models,looks like the severe area to be all along and south of the i74 corridor for this evening into the night hours.areas north of this looks like it is stablizing.

Homeboy there is storms brewing now and spc put out a meso requiring a watch shortly for this area.
MESOSCALE DISCUSSION 0731
NWS STORM PREDICTION CENTER NORMAN OK
0122 PM CDT SUN MAY 06 2012
AREAS AFFECTED...NRN MO...WRN/NRN IL
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 061822Z - 061915Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...SEVERE THUNDERSTORMS SHOULD INCREASE IN AREAL COVERAGE
ALONG AN OUTFLOW/FRONTAL ZONE THAT STRETCHES FROM NRN IL INTO NRN MO
OVER THE NEXT FEW HOURS.
DISCUSSION...STRONG HEATING IS CONTRIBUTING TO A VERY UNSTABLE
AIRMASS ACROSS PARTS OF THE MID MS VALLEY THIS AFTERNOON WITH A
CORRIDOR OF INSTABILITY ON THE ORDER OF 3000-4000 J/KG ACROSS MO
INTO CNTRL IL. ALTHOUGH DEEP LAYER SHEAR IS NOT PARTICULARLY
STRONG...IT APPEARS SEVERE THUNDERSTORMS ARE BECOMING INCREASINGLY
LIKELY ALONG AN EXTENSIVE OUTFLOW/FRONTAL ZONE THAT STRETCHES FROM
NRN IL...INTO NRN MO. RECENT CONVECTIVE DEVELOPMENT ALONG THIS ZONE
JUST EAST OF MCI AND EAST OF MLI SUGGEST A MORE FAVORABLE BOUNDARY
LAYER FOR ROBUST UPDRAFTS. WITH AN EXPANDING WARM SECTOR CU FIELD
IT APPEARS ADDITIONAL STORMS ARE LIKELY TO DEVELOP WITH A SUBSEQUENT
ESEWD MOVEMENT OFF THE BOUNDARY INTO A VERY BUOYANT AIRMASS. LARGE
HAIL CAN BE EXPECTED ALONG WITH POTENTIALLY DAMAGING WINDS. ALONG
THE NRN OUTFLOW ACROSS NRN IL SHEAR PROFILES ARE A BIT MORE
FAVORABLE FOR ROTATING UPDRAFTS AND ISOLATED SUPERCELL DEVELOPMENT
HOWEVER HAIL/WINDS SHOULD PROVE THE DOMINANT THREAT.
