   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 041524Z - 041630Z
   
   PORTIONS OF SRN INDIANA AND NRN KENTUCKY...AND PERHAPS EXTREME SWRN
   OHIO...ARE BEING MONITORED FOR A POSSIBLE WW ISSUANCE DURING THE
   NEXT HOUR OR SO.
   
   AT 15Z...A SHORT LINE OF STORMS EXTENDED NEAR THE ILLINOIS/INDIANA
   BORDER FROM EAST OF HUF TO NEAR HUF TO 50 SSE MTO. THESE STORMS ARE
   BEING SUPPORTED BY AN APPARENT MCV...LOCATED IN CENTRAL IL.
   INSTABILITY AXIS IS CURRENTLY LOCATED ALONG THE OHIO RIVER...WHERE
   MORNING SUNSHINE HAS WARMED TEMPERATURES INTO LOWER 80S. THE STORMS
   APPEAR TO BE SLIGHTLY ELEVATED AT THIS TIME...BUT ARE LIKELY TO
   BECOME ROOTED IN THE BOUNDARY LAYER AS THEY MOVE SEWD INTO BOTH THE 
   WARMING AND MORE UNSTABLE ENVIRONMENT. THE STRENGTHENING INSTABILITY
   AND 30-40 KT WNWLY MID LEVEL WINDS WOULD BE SUPPORTIVE OF AN
   INCREASING WIND THREAT WITH THE LINE AS IT MOVES SEWD...AND A WW MAY
   BE NEEDED SOON.
