AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
738 PM CDT WED MAY 3 2006

.DISCUSSION...

THUNDERSTORMS THAT DEVELOPED OVER THE MIDSOUTH THIS AFTERNOON HAVE
BEEN SHOWING SIGNS OF WEAKENING OVER THE PAST HOUR. THE LINE OF
STORMS FROM THE MISSOURI BOOTHEEL TO CHERRY VALLEY IN NORTHEAST
ARKANSAS WAS STILL ACTIVE. GOOD CONVERGENCE ALONG THE LOW LEVEL
BOUNDARY AS SEEN ON VISIBLE SATELLITE AND THE CENTER OF THE MCV
MOVING ACROSS THIS AREA HAS ALLOWED THESE STORMS TO PERSIST. WITH
LOSS OF DAYTIME HEATING...THE STORMS ARE SUBSIDING ACROSS THE
MIDSOUTH. THE POSSIBILITY OF ISOLATED SEVERE STORMS WILL REMAIN
POSSIBLE FOR THE NEXT HOUR OR TWO.

ADDITIONAL THUNDERSTORM DEVELOPMENT WILL CONTINUE OVER MIDDLE
TENNESSEE WHERE THE BETTER INSTABILITY HAS SHIFTED. LATE TONIGHT
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE ACROSS
THE MIDSOUTH.
