Area forecast discussion, May 22, 2:43 PM EDT, 2 hours 2 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
243 PM EDT SUN MAY 22 2011

.SHORT TERM...(TONIGHT AND MONDAY)...HIGH PRESSURE TO OUR SOUTH AND
EAST WILL KEEP A MOISTER SOUTHWESTERLY FLOW INTO THE AREA.  WITH
INCREASED MOISTURE AND INSTABILITY...EXPECT MORE IN THE WAY OF
CONVECTION FOR THE SHORT TERM.  SOME AFTERNOON CONVECTION ALREADY
FIRING OVER THE AREA...AND SPC HAS ISSUED A SEVERE THUNDERSTORM
WATCH FOR MUCH OF THE AREA THROUGH 01Z.  MODELS ALSO HINT AT SOME
WEAK SHORT WAVE ENERGY PERHAPS BRINGING ADDITIONAL CONVECTION LATER
TONIGHT.  WILL NOT TRY TO TIME CONVECTION AT THIS POINT...BUT WILL
BROAD BRUSH MAINLY CHANCE POPS (EXCEPT SLIGHT CHANCE POPS SOUTH MON)
THROUGH TOMORROW...WITH HIGHEST POPS NORTH AND NORTHWEST ZONES.  MAV
TEMPS GENERALLY LOOK REASONABLE...SO WILL STAY CLOSE.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)...NOT TOO MUCH CHANGE NOTED
IN LATEST MODEL/ENSEMBLE RUNS FROM PREVIOUS RUNS. A SERIES OF WEAK
UPPER-LEVEL DISTURBANCES WILL CONTINUE TO RIPPLE THROUGH A
LOW-AMPLITUDE FLOW AS A QUASI-STATIONARY SURFACE BOUNDARY LURKS JUST
TO OUR NORTH THROUGH MID-WEEK. POTENTIALLY MORE SIGNIFICANT SYSTEM
STILL ON TRACK TO AFFECT THE SOUTHERN APPALACHIAN REGION BY LATE
WORK WEEK. STILL SIGNIFICANT DIFFERENCES IN TIMING BETWEEN THE ECMWF
AND GFS MODELS. TENDED TO FAVOR FASTER GFS SOLUTION SINCE IT HAS
SUPPORT OF MOST OF THE GEFS ENSEMBLE MEMBERS. FOR TEMPS...GENERALLY
DID NOT DEVIATE MUCH FROM MAV/MEX GUIDANCE.
