VALID 041200Z - 051200Z

...NO SVR TSTM AREAS FORECAST...

...MID MS AND OH VALLEYS...
AN UPPER TROUGH CURRENTLY OVER THE WESTERN UNITED STATES WILL MOVE
EASTWARD AND AMPLIFY OVER THE CENTRAL STATES ON TUESDAY.
MEANWHILE...THE ASSOCIATED SURFACE COLD FRONT WILL SAG SOUTHEASTWARD
ACROSS THE MID MS AND OH VALLEYS. SOUTHWESTERLY LOW LEVEL WINDS
SOUTH OF THE FRONT WILL HELP TO MAINTAIN DEWPOINTS IN THE 50S TO
LOWER 60S...PROVIDING SUFFICIENT INSTABILITY FOR NUMEROUS SHOWERS
AND ISOLATED THUNDERSTORMS ALONG/AHEAD OF THE FRONT. MODEL SOLUTIONS
INDICATE THAT FAVORABLE LOW/MID LEVEL WIND SHEAR WILL DEVELOP ALONG
A NARROW CORRIDOR ACROSS PARTS OF KY/TN ON TUESDAY AFTERNOON. THIS
ZONE WOULD HAVE THE HIGHEST THREAT FOR MORE ORGANIZED CONVECTION.
HOWEVER...WIDESPREAD LOW CLOUDS WILL LIMIT DAYTIME
HEATING/DESTABILIZATION SUCH THAT THE RISK OF SEVERE STORMS DOES NOT
APPEAR TO WARRANT A 5 PERCENT AREA.
