AREAS AFFECTED...FAR SRN IND AND NRN KY

CONCERNING...SEVERE THUNDERSTORM WATCH 390...

VALID 250159Z - 250330Z

A BOW ECHO WILL CONTINUE EWD ACROSS FAR SRN IND AND INTO NRN KY WITH
A POTENTIAL FOR ISOLATED WIND DAMAGE AND HAIL. THE THREAT MAY EXTEND
AS FAR EAST AS LOUISVILLE BUT WEAKENING OF THE LINE IS ANTICIPATED
AS THE LINE MOVES EWD INTO DECREASING INSTABILITY.

LATEST SFC ANALYSIS CURRENTLY SHOWS A WARM FRONT EXTENDING SWD
ACROSS WRN IND INTO WRN KY. MODERATE INSTABILITY IS LOCATED WEST OF
THE FRONT WITH A TIGHT INSTABILITY GRADIENT PRESENT ALONG THE
FRONTAL BOUNDARY. THE LINEAR MCS IS MOVING EWD ALONG THE INSTABILITY
GRADIENT WITH A 50 KT MID-LEVEL JET LOCATED JUST BEHIND THE MCS. THE
UPPER-SYSTEM ASSOCIATED WITH THE JET IS ENHANCING LIFT AND SHEAR
WHICH MAY SUSTAIN THE SEVERE THREAT WITH THE MCS FOR ANOTHER HOUR OR
SO. HOWEVER...AS THE LINEAR MCS MOVES INTO WEAKENING INSTABILITY
ACROSS NRN KY AND SERN IND...THE SEVERE THREAT SHOULD BEGIN TO
DIMINISH ACROSS THE REGION.
