AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 321 PM EDT FRI JUN 27 2014 .SHORT TERM (TONIGHT AND SATURDAY)... A MOIST AIR MASS WILL REMAIN IN PLACE OVER THE AREA THROUGH THE SHORT TERM PERIOD. BEST SHOWER COVERAGE THROUGH THE EVENING WILL BE IN SOUTHERN SECTIONS...WITH DECREASING ACTIVITY AFTER SUNSET. THE SLOW-MOVING STORMS WILL NEED TO BE MONITORED FOR LOCALIZED FLOODING THROUGH THE EVENING. THERE IS LITTLE FORCING FOR LIFT OVERNIGHT...BUT A CHANCE OF SHOWERS CONTINUES AS EVEN THE SLIGHTEST FORCING COULD PRODUCE A SHOWER IN THE MOIST ENVIRONMENT. PRECIP CHANCES RISE TO LIKELY TOMORROW AS THE MODELS SHOW A 500 MB VORT MAX NOW IN THE WESTERN GULF LIFTING NE AND AFFECTING THE TN VALLEY TOMORROW AFTERNOON. PW VALUES TOMORROW WILL BE AROUND 1.7 INCHES WITH TALL/SKINNY CAPE PROFILES IN FORECAST SOUNDINGS...SO HEAVY RAIN AND LOCALIZED FLOODING WILL BE THE MAIN THREATS. WITH GREATER CLOUD COVER EXPECTED TOMORROW...HIGHS SHOULD BE A FEW DEGREES COOLER THAN WHAT WE ARE SEEING TODAY. .LONG TERM (SATURDAY NIGHT THROUGH FRIDAY)... OVERALL...CHANCES FOR SHOWERS AND THUNDERSTORMS EXIST EACH DAY THROUGH MOST OF THE EXTENDED WITH A DRIER PATTERN IN STORE TOWARD THE END. IT IS LOOKING LIKE THE FOURTH OF JULY IS SHAPING UP TO BE A DRY AND PLEASANT ONE WITH A LITTLE LOWER HUMIDITY VALUES DUE TO A FRONTAL PASSAGE ON WED/THURSDAY. SATURDAY NIGHT...UPPER LEVEL SHORTWAVE WILL CONTINUE TO LIFT NORTH OF OUR AREA PROVIDING A GOOD CHANCE FOR SHOWERS AND THUNDERSTORMS. AS THE NIGHT PROGRESSES...SHOWERS AND STORMS SHOULD BEGIN TO DISSIPATE. A FEW SHOWERS AND STORMS MAY LINGER THROUGH THE NIGHT. WITH HIGH PRESSURE STILL IN PLACE ON SUNDAY...AN UPPER LEVEL TROUGH WILL APPROACH FROM THE WEST AND BECOME EXTREMELY NEGATIVELY TILTED THE CLOSER IT GETS TO OUR AREA. OUT AHEAD OF THIS FEATURE...SHOWERS AND STORMS ARE POSSIBLE SUNDAY AFTERNOON. THE WEAK ASSOCIATED FRONTAL BOUNDARY MOVES THROUGH SUNDAY NIGHT INTO MONDAY. THE HIGH PRESSURE THAT WAS OVER US DURING THE WEEKEND STARTS SHIFTING EAST ON MONDAY WITH AGAIN MORE DIURNAL CONVECTION MONDAY AFTERNOON. LITTLE IF ANY LIFT PRESENT WITH THE PASSING FRONTAL BOUNDARY...SO SHOWERS AND STORMS WILL MAINLY BE DIURNAL. BY TUESDAY A DEEPER TROUGH IS APPROACHING THE OHIO RIVER VALLEY AND WILL SWING THROUGH OUR REGION ON TUES NIGHT INTO THURSDAY. TUESDAY AFTERNOON LOOKS DRY BUT BY TUESDAY EVENING A COLD FRONT ASSOCIATED WITH THE DEEPER TROUGH MOVES INTO OUR AREA TRIGGERING SHOWERS AND STORMS. THERE IS SOME MODEL DISAGREEMENT ON HOW FAST THE FRONTAL BOUNDARY MOVES THROUGH. THE GFS HANGS THE FRONT UP ACROSS OUR AREA ON WEDNESDAY...PROVIDING A TRIGGER FOR MORE SHOWERS AND STORMS BEFORE MOVING THE BOUNDARY OUT BY THURSDAY MORNING. WHEREAS THE ECMWF HAS THE BOUNDARY TO OUR SOUTH AND EAST BY WEDNESDAY AFTERNOON...THUS KEEPING US MORE DRY. WILL COMPROMISE BETWEEN THE TWO MODELS AND KEEP SOME CHANCE OF POPS IN FOR WEDNESDAY UNTIL THE MODELS CAN BETTER RESOLVE THE TIMING. THURSDAY...MUCH DRIER AIR FILTERS IN BEHIND THE FRONT ALLOWING FOR A MOSTLY PRECIP FREE DAY...WILL STILL KEEP A SLIGHT CHANCE POP IN BUT POPS MAY BE ABLE TO BE DROPPED WITH FUTURE FORECAST ISSUANCES. FRIDAY...THE 4TH OF JULY...APPEARS TO BE DRY AS WELL AS DRIER AIR IS STILL IN PLACE...WITH HIGH PRESSURE STARTING TO BUILD BACK IN.
