AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
209 PM EDT FRI JUL 14 2006

.SHORT TERM (TONIGHT THROUGH SATURDAY)...
THUNDERSTORMS INITIATED BY SURFACE HEATING IN THE PLATEAU WILL MOVE
EAST INTO THE VALLEY THROUGH THE EVENING. A FEW OF THE STORMS
COULD BECOME STRONG ENOUGH TO PRODUCE ISOLATED WIND DAMAGE. BEST
INSTABILITY IN LAPS MESOANALYSIS APPEARS TO BE IN THE SOUTHERN AND
CENTRAL VALLEY WHERE CAPES ARE OVER 2500 J/KG. WITH LITTLE UPPER
LEVEL SUPPORT...THE STORMS WILL LIKELY DISSIPATE BY MIDNIGHT. POPS
INCREASE AGAIN TOMORROW MORNING AS A TROUGH AXIS NOW CROSSING THE
MID MISSISSIPPI RIVER VALLEY WILL APPROACH THE AREA. THE MODELS
HAVE COME INTO BETTER AGREEMENT WITH THE TIMING OF THE VORT AXIS
AND BEST LIFT...BRINGING IT INTO OUR NORTHWESTERN COUNTIES AROUND
12Z AND EXITING TO THE SOUTHEAST AROUND 21Z. WILL HAVE HIGH CHANCE
POPS IN THIS TIME FRAME. THE LIFT DOES NOT APPEAR TO BE VERY STRONG
DUE TO THE LACK OF LOW LEVEL FORCING...SURFACE WINDS ARE WESTERLY
AND DIFFLUENT. TIMING OF THE TROUGH PASSAGE IN THE MORNING/EARLY
AFTERNOON WILL ALSO NOT BE IDEAL FOR MAXIMIZING INSTABILITY...SO
THE POTENTIAL FOR WIDESPREAD SEVERE WEATHER LOOKS LOW.

.LONG TERM (SATURDAY NIGHT THROUGH FRIDAY)...
UPPER TROUGH AXIS IS THROUGH THE AREA BY 00Z SUNDAY AND MUCH DRIER
AIR ALOFT MOVES IN QUICKLY...SO POPS WILL BE REMOVED FROM SATURDAY
NIGHT EXCEPT FOR A SLIGHT CHANCE IN THE EVENING IN THE MOUNTAINS. ON
SUNDAY A LARGE AREA OF HIGH PRESSURE WILL MOVE SLOWLY FROM THE
PLAINS TO THE ATLANTIC COAST THROUGH THE PERIOD. THE 500 MB CENTER
OF THE HIGH WILL SLOWLY DRIFT TO THE EAST AND BE OVER OUR AREA ON
THURSDAY. SUBSIDENCE UNDER THE RIDGE WILL PROMOTE A DRY AND STABLE
ATMOSPHERE. THUS WILL HAVE A PERSISTENCE FORECAST OF DRY CONDITIONS
WITH ABOVE NORMAL TEMPERATURES FOR SUNDAY THROUGH THURSDAY. HIGH
TEMPS SHOULD EASILY REACH THE MID 90S IN THE VALLEY. ON FRIDAY THE
UPPER RIDGE MOVES OFFSHORE...ALLOWING SOME MOISTURE ADVECTION AND
SLIGHT DESTABILIZATION. WILL HAVE A SLIGHT CHANCE POP FRIDAY
AFTERNOON WITH SLIGHTLY COOLER TEMPS.
