Area forecast discussion, Jul 4, 2:25 PM EST, 25 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 325 PM EDT WED JUL 4 2012 .SHORT TERM (TONIGHT AND THURSDAY)...CURRENT SURFACE ANALYSIS SHOWS A HOT...HUMID...AND STAGNANT AIR MASS OVER THE FORECAST AREA...WITH RADARS REVEALING SCATTERED CONVECTION OVER THE ENTIRE REGION. MODELS INDICATE THAT A MODERATELY TO POTENTIALLY HIGHLY UNSTABLE AIR MASS WILL DEVELOP OVER THE FORECAST AREA ON THURSDAY...WITH AN UPPER- LEVEL SHORT WAVE PROGGED TO MOVE SOUTHWARD OVER THE FORECAST AREA ALONG THE EASTERN PERIPHERY OF AN UPPER-LEVEL HIGH CENTERED OVER THE CENTRAL PLAINS. THIS SHORT WAVE HAS ALREADY TRIGGERED A MESOSCALE CONVECTIVE SYSTEM (MCS) OVER NORTHERN MN THIS AFTERNOON...WHICH SHOULD THEN MOVE SOUTHEASTWARD ACROSS THE GREAT LAKES REGION INTO THE OHIO RIVER VALLEY TONIGHT...AND THEN SOUTHWARD INTO THE FORECAST AREA ON THURSDAY. THIS MCS WILL HAVE TO POTENTIAL TO PRODUCE A WIDESPREAD DAMAGING WIND EVENT ALONG WITH LOCALLY HEAVY RAINFALL AND FREQUENT CLOUD TO GROUND LIGHTNING...ESPECIALLY IF IT ARRIVES IN THE AFTERNOON HOURS WHEN PEAK HEATING COULD CREATE A POTENTIALLY HIGHLY UNSTABLE AIR MASS OVER THE FORECAST AREA. WITH THIS IN MIND...WILL MENTION THE POSSIBILITY OF DAMAGING WINDS AND LOCALLY HEAVY RAINFALL IN THE ZONES. AS FOR TEMPS...WILL GENERALLY TREND TOWARDS A PERSISTENCE FORECAST...BUT WITH SLIGHTLY COOLER TEMPS ON THURSDAY DUE TO THE EXPECTED CLOUD COVER AND PRECIP COVERAGE. .LONG TERM (THURSDAY NIGHT THROUGH WEDNESDAY)...THE UPPER RIDGE OVER THE PLAINS IS FIRMLY IN PLACE THURSDAY NIGHT. THE FORECAST AREA WILL BE UNDER THE INFLUENCE BUT ON THE EASTERN EDGE. DIURNAL STORMS WILL LIKELY BE DYING OUT LATE THURSDAY EVENING AS IS TYPICAL THIS TIME OF YEAR. CONFIDENCE RATHER LOW FOR PRECIP CHANCES ON FRIDAY WITH DIVERGENT MODEL SOLUTIONS. THE NAM PICKS UP ON A SHORTWAVE AND ASSOCIATED MCS MOVING ACROSS EASTERN KY WHILE THE GFS PICKS UP WIDELY SCATTERED/ ISOLATED STORMS OVER THE E TN MOUNTAINS. LOW END CHANCE POPS ACROSS THE AREA BY FRIDAY AFTERNOON LOOKS REASONABLE. THE BIGGER STORY THAN THE PRECIP CHANCES WILL BE THE HEAT ON FRIDAY INTO SATURDAY. AHEAD OF A WEAK COLD FRONT...SURFACE DEWPOINTS WILL BE ON THE RISE ALONG WITH THE TEMPERATURES. THUS HEAT INDICES WILL APPROACH 105 DEGREES. THIS WILL BE SOMETHING TO WATCH OVER THE NEXT COUPLE OF DAYS. BY SUNDAY...SOME RELIEF TO THE HEAT MAY BE ON THE WAY. LONGER RANGE MODELS HAVE BEEN CONSISTENT IN PRODUCING RAINFALL FOR THE FORECAST AREA. THERE ARE HINTS OF SLOWING THIS FEATURE SO IF RAIN DOES NOT MAKE IT BY SUNDAY AFTERNOON...SUNDAY NIGHT AND MONDAY LOOK LIKE THE BEST BET. THE FRONTAL BOUNDARY SHOULD STALL IN THE VICINITY EARLY NEXT WEEK HOPEFULLY SERVING AS A FOCUS FOR MORE SHOWERS AND THUNDERSTORMS TO BRING THE MUCH NEEDED RAINFALL THIS AREA NEEDS. && .PRELIMINARY POINT TEMPS/POPS...
