AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
959 AM EDT SUN APR 28 2002

RADAR TRENDS SHOW THE STORMS ACROSS MIDDLE TENNESSEE...PLATEAU AND
SOUTHWEST VIRGINIA ARE WEAKENING AS THEY MOVE INTO MORE STABLE AIR.
HOWEVER...SCATTERED SHOWERS AND THUNDERSTORMS REMAIN AND WILL MOVE
ACROSS THE REGION THIS MORNING.  A GOOD DEAL OF CONVECTIVE DEBRIS
WILL MOVE OVER THE REGION THIS MORNING INTO POSSIBLY EARLY
AFTERNOON WHICH WILL INHIBIT DESTABILIZATION FOR A WHILE...BUT WITH
STRONG WARM AIR ADVECTION AND RETURN OF SUNSHINE LATER TODAY FEEL
AIRMASS WILL UNSTABLE.  I EXPECT LIFTED INDICES OF -5 TO -7 WITH
CAPES BETWEEN 2000-2500 J/KG.

COLD FRONT STILL WELL WEST/NORTHWEST OF THE AREA AND WILL NOT MOVE
ACROSS THE FORECAST AREA UNTIL THIS EVENING. I EXPECT ANOTHER ROUND
OF THUNDERSTORMS TO FIRE OVER CENTRAL/EAST KENTUCKY TO MIDDLE
TENNESSEE THIS AFTERNOON WHERE AIRMASS WITH BE QUITE UNSTABLE.  THE
ACTIVITY WILL THEN MOVE EAST INTO THE CWA LATE THIS
AFTERNOON/EVENING.  SOME OF THESE STORMS COULD BECOME SEVERE WITH
THE GREATEST THREAT OVER THE NORTHERN COUNTIES WHERE LOW LEVEL
INFLOW AND DYNAMICS WILL BE BEST.

BESIDES STORM THREAT...STRONG LOW LEVEL SOUTHWEST JET OVER THE
REGION TODAY (NEAR 40 KNOTS) WILL PRODUCE WINDY CONDITIONS AREA-WIDE.
HAVE EXPANDED WIND ADVISORY TO COVER THE ENTIRE FORECAST AREA.
