AREAS AFFECTED...FAR SOUTHERN INDIANA AND THE WESTERN HALF OF KY

CONCERNING...SEVERE THUNDERSTORM WATCH 290...

VALID 232358Z - 240200Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 290
CONTINUES.

SUMMARY...GREATEST SEVERE WEATHER THREAT WILL TEND TO BE WITH THE
LEADING W-E ORIENTED BAND OF STORMS MOVING TO THE SOUTHEAST ACROSS
THE SOUTHERN HALF OF WW 290.  NEW STORMS ARE GRADUALLY DEVELOPING
ALONG THE WESTERN FLANK OF THIS BAND INTO WESTERN KY.  ADDITIONAL
STRONG TO SEVERE STORMS WILL BE POSSIBLE ACROSS FAR SOUTHERN INDIANA
TO ADJACENT KY /IN THE NORTHERN HALF OF WW 290/ AS STORMS FORM ALONG
THE SOUTHWARD-MOVING COLD FRONT.

DISCUSSION...THE ENVIRONMENT ACROSS WW 290 REMAINS VERY UNSTABLE
WITH MLCAPE OF 2500-3500 J/KG BOTH ALONG AND SOUTH OF THE LEADING
BAND OF STORMS MOVING TO THE SOUTHEAST ACROSS CENTRAL/SOUTHERN KY
AND ACROSS SOUTHERN INDIANA AND ADJACENT KY COUNTIES.  EFFECTIVE
BULK SHEAR REMAINS THE GREATEST ACROSS ACROSS SOUTHERN INDIANA INTO
NORTHERN KY...SUGGESTING STORMS THAT FORM ALONG THE COLD FRONT AS IT
MOVES SOUTHWARD THROUGH THE VERY STRONG INSTABILITY WILL HAVE A
THREAT FOR DAMAGING WINDS AND/OR HAIL.  MEANWHILE...THE BAND OF
STORMS MOVING INTO SOUTHERN KY AND NEW DEVELOPMENT ALONG ITS WESTERN
FLANK WILL HAVE A SEVERE RISK FOR MAINLY DAMAGING WINDS AS THIS
ACTIVITY WILL MOVE INTO WEAKER DEEP-LAYER SHEAR AND BE ENHANCED BY
STORM MERGERS/COLD POOL FORMATION.
