AREAS AFFECTED...CNTRL IL TO NRN MO AND FAR SRN IA
CONCERNING...TORNADO WATCH 232...
VALID 032342Z - 040045Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 232 CONTINUES.
SUMMARY...NEW WW PROPOSAL WILL BE COORDINATED SOON FOR AREAS W OF WW
232 AS TSTMS LIKELY INCREASE IN COVERAGE WITHIN A DIFFERENTIAL
HEATING ZONE/REMNANT OUTFLOW BOUNDARY.
DISCUSSION...CONVECTION HAS GRADUALLY INCREASED ALONG A REMNANT
OUTFLOW BOUNDARY FROM NEAR PIA W/SWWD TO NRN MO. AIR MASS S OF THIS
BOUNDARY IS STRONGLY UNSTABLE WITH MLCAPE OF 2500 TO 3500 J/KG AND
PARTIAL 00Z TOP/ILX/DVN RAOBS INDICATING MINIMAL MLCIN. TSTMS SHOULD
BLOSSOM WITHIN THIS CORRIDOR BY SUNSET AS THE LLJ INTENSIFIES THIS
EVENING. PRIMARY INITIAL THREATS SHOULD BE LARGE /POTENTIALLY
SIGNIFICANT/ HAIL AND PERHAPS A BRIEF TORNADO. UPSCALE GROWTH INTO
AN MCS APPEARS PLAUSIBLE WITH THE RISK TRANSITIONING TO DAMAGING
WINDS LATER THIS EVENING.
