Severe Thunderstorm Warning 29, NWS Morristown, TN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
230 PM EDT SUN MAY 16 2004

.SHORT TERM (TONIGHT AND MONDAY)...THUNDERSTORMS CONTINUING TO
DEVELOP OVER THE AREA THIS AFTERNOON AS A RESULT OF A STALLED
FRONTAL BOUNDARY ACROSS TENNESSEE. THERE IS LITTLE IN THE WAY OF
UPPER LEVEL SUPPORT BUT THE LOWER ATMOSPHERE REMAINS WEAKLY UNSTABLE
AND WITH SUFFICIENT LOW LEVEL MOISTURE...EXPECT THUNDERSTORMS TO
CONTINUE OVER THE AREA FOR MUCH OF THE EVENING. THUNDERSTORMS ARE
EXPECTED TO DECREASE AFTER SUNSET WITH THE LOSS OF DAYTIME HEATING.
HOWEVER...SHOWERS AND THUNDERSTORMS WILL REFORM OVER THE AREA ON
MONDAY WITH THE BOUNDARY REMAINING IN THE VICINITY AND THE AIR MASS
DESTABILIZING ONCE AGAIN.

.LONG TERM (MONDAY NIGHT THROUGH SUNDAY)...A MOIST AND UNSTABLE
AIRMASS WILL REMAIN ACROSS THE FORECAST AREA THROUGHOUT THE WEEK...
AS HIGH PRESSURE BUILDS ACROSS THE SOUTHEAST WITH ZONAL FLOW ALOFT.
AS A RESULT...THINK THAT DIURNALLY-DRIVEN ISOLATED CONVECTION WILL
CONTINUE EACH DAY DURING THE AFTERNOON AND EVENING...ESPECIALLY
ACROSS THE HIGHER ELEVATIONS. ANOTHER WEAK COLD FRONT WILL SLOWLY
MOVE TOWARD THE FORECAST AREA ON TUESDAY...BUT IT SHOULD BECOME
STATIONARY ACROSS THE OHIO RIVER VALLEY WITH A STRONG RIDGE
ENTRENCHED OVER THE SOUTHEAST. YET ANOTHER WEAK COLD FRONT WILL
APPROACH THE FORECAST AREA ON FRIDAY...BUT THIS ONE WILL ALSO LIKELY
STALL-OUT ACROSS THE OHIO RIVER VALLEY WITH THE RIDGE HOLDING FIRM
OVER THE SOUTHEAST.
