VALID 270020Z - 270115Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
110...111...CONTINUES.

SUMMARY...AN ONGOING LINE OF THUNDERSTORMS ACROSS SRN IND INTO
WRN/CNTRL KY WILL POSE MAINLY A DAMAGING WIND THREAT. SCATTERED
CONVECTION AHEAD OF THIS LINE WILL CONTINUE TO HAVE AN ISOLATED
LARGE HAIL AND STRONG/GUSTY WIND THREAT.

DISCUSSION...MCS ACROSS SRN IND INTO WRN/CNTRL KY IS MOVING EWD
AROUND 40-45 KT AS OF 00Z. BASE VELOCITY DATA FROM KLVX SHOW 50+ KT
INBOUND VELOCITIES ASSOCIATED WITH THIS MCS AT 1500 FT AGL. SFC
OBSERVATIONS AND SPOTTER REPORTS SUGGEST SFC WINDS ARE NEAR/ABOVE
SEVERE LEVELS. THE ENVIRONMENT DOWNSTREAM IS WEAKLY UNSTABLE...WITH
MLCAPE OF 500-1000 J/KG. THIS SUFFICIENT INSTABILITY COMBINED WITH
MODESTLY ENHANCED MID-LEVEL FLOW SHOULD ALLOW STRONG TO DAMAGING
WINDS TO REMAIN THE PRIMARY THREAT WITH THIS ONGOING MCS AS IT MOVES
EWD ACROSS KY AND SRN IND OVER THE NEXT SEVERAL HOURS. SCATTERED
CLUSTERS OF CONVECTION ACROSS ERN KY...SRN OH...AND WV TO THE S OF A
COLD FRONT WILL CONTINUE TO POSE AN ISOLATED LARGE HAIL AND
STRONG/GUSTY WIND THREAT. OVERALL...SEVERE THREAT ACROSS WW 110 AND
111 SHOULD GRADUALLY DIMINISH OVER THE NEXT FEW HOURS AS INSTABILITY
WEAKENS AND ONGOING CONVECTION PROBABLY BECOMES SLIGHTLY ELEVATED.
