Area forecast discussion, Jun 29, 3:23 PM EDT, 2 hours 6 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 323 PM EDT FRI JUN 29 2001 NUMEROUS THUNDERSTORMS CONTINUE TO MOVE NORTHWARD UP THE VALLEY THIS AFTERNOON. EXPECT THIS AREA OF STORMS TO CONTINUE TO MOVE NORTHWARD AND AFFECT NE TN AND SW VA INTO THE EVENING. COULD ALSO SEE MORE STORMS DEVELOP IN SE TN AND SW NC WHERE THEY WILL HAVE THE MOST TIME TO DESTABILIZE AGAIN. MODELS CONTINUE TO BE IN DECENT AGREEMENT WITH THE FILLING IN OF THE UPPER LOW...AS IT MOVES SLOWLY SOUTHWEST. ALL OF THE MODELS INDICATE THAT THE WEAK SHORTWAVE OVER AL WILL MOVE ACROSS THE CWA AS IT WEAKENS TONIGHT. OTHERWISE MORE OF THE SAME...DECENT MOISTURE... INSTABILITY...AND WEAK FORCING LEADING TO AFTERNOON AND EVENING STORMS. MAV/FWC TEMPS ARE CLOSE AND WILL FOLLOW THEM. MOST OF THE STORMS TONIGHT WILL DISSIPATE WITH THE LOSS OF THE HEATING. HOWEVER WILL KEEP THE CHANCE POPS GOING THROUGH THE OVERNIGHT IN NE TN AND SW VA...GIVEN THAT THE 50H SHORTWAVE WILL STILL BE MOVE THROUGH THE REGION. WITH THE 50H LOW WEAKENING AND MOVING FATHER AWAY...EVEN THE 50H SHORTWAVES STOP PIVOTING AROUND FOR SATURDAY AND SUNDAY. FLOW IS WEAK SO UPSLOPE COMPONENT WILL ALSO CONTINUE TO BE WEAK. HOWEVER...CAPES ARE STILL EXPECTED TO BE BETWEEN 1500 AND 2500 J/KG ON BOTH DAYS. THERE IS ENOUGH MOISTURE AND INSTABILITY TO KEEP SCT THUNDERSTORMS IN THE FORECAST FOR BOTH DAYS. AS FOR THE EXTENDED...IT LOOKS AS IF THE LONG RANGE MODELS ARE NOW SUGGESTING THAT U/L RIDGING IN THE WEST WILL LEAD TO U/L TROUGHING IN THE EAST. AT THE SURFACE...THE WEATHER FEATURES ARE EVEN MORE SUPPORTIVE FOR PRECIPITATION (MAINLY DIURNAL)...AS FRONTAL BOUNDARIES WILL APPROACH OR MOVE INTO THE FORECAST AREA. THE ONLY PERIOD CONFIDENT ENOUGH TO GO WITH DRY CONDITIONS WILL BE ON FRIDAY.
