AREAS AFFECTED...CNTRL IL...NRN/CNTRL INDIANA...WRN OH
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 151923Z - 152100Z
PROBABILITY OF WATCH ISSUANCE...60 PERCENT
SUMMARY...POTENTIAL FOR ISOLATED DMGG WIND GUSTS AND HAIL APPEARS TO
BE INCREASING ACROSS PARTS OF CNTRL IL AND CNTRL INDIANA IN
ASSOCIATION WITH DEVELOPING TSTMS. TRENDS ARE BEING MONITORED FOR A
POSSIBLE WW.
DISCUSSION...VISIBLE SATELLITE TRENDS SHOW INCREASING TOWERING CU
AND ISOLATED TSTM DEVELOPMENT WITHIN A BROAD CONFLUENCE ZONE ACROSS
CNTRL IL...AND ACROSS W-CNTRL/N-CNTRL IND. STRONG HEATING WITHIN A
VERY MOIST BOUNDARY LAYER IS RESULTING IN MODERATE TO EXTREME
INSTABILITY /AOA 2500 J/KG/...WHICH WILL SUPPORT VIGOROUS UPDRAFT
DEVELOPMENT OVER THE NEXT 2-3 HRS. ALTHOUGH FORCING FOR ASCENT IS
GENERALLY WEAK...AND SFC FLOW VEERED/WLY...THE MOIST AND UNCAPPED
AIR MASS WILL BE SUPPORTIVE FOR THE DEVELOPMENT OF A FEW MULTICELL
CLUSTERS GIVEN 20-30 KT OF EFFECTIVE SHEAR...WITH THE PRIMARY THREAT
BEING DMGG WIND GUSTS...ENHANCED BY THE STEEPENING OF LOW-LEVEL
LAPSE RATES ACROSS THE AREA. ISOLATED INSTANCES OF SVR HAIL ARE ALSO
POSSIBLE GIVEN THE DEGREE OF INSTABILITY...DESPITE RELATIVELY WARM
TEMPERATURES ALOFT. CONVECTIVE TRENDS ARE BEING CLOSELY MONITORED
FOR SIGNS OF INCREASING TSTM COVERAGE...WHICH COULD NECESSITATE THE
ISSUANCE OF A NEW WW ACROSS PARTS OF CNTRL IL...NRN/CNTRL IND...AND
NWRN OH THIS AFTERNOON.
