AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 320 PM EDT FRI AUG 8 2014 .SHORT TERM (TONIGHT AND SATURDAY)...SURFACE WARM FRONT EXTENDS NE THROUGH SOUTHEAST TN AND CONTINUES THROUGH N MIDDLE TN. A SHORT WAVE WILL MOVE SLOWLY INTO MIDDLE TN THROUGH THE PERIOD. SURFACE LOW PRESSURE WILL ACCOMPANY THE FRONT. WARM AND MOST AIRMASS IN PLACE. PWAT VALUES NEAR 2.00 AND DEEP WARM CLOUD LAYER WILL MAKE CONDITIONS FOR HEAVY RAINFALL AND LOCALIZED FLOODING POSSIBLE. TIMING AND PLACEMENT OF EXTENDED PERIODS OF RAINFALL REMAIN UNCERTAIN WITH RELATIVELY WEAK SYNOPTIC FEATURES. MOST FAVORABLE AREAS ARE ACROSS NE TN AND SW VA MAINLY DUE TO STORM MOTION AND LOCATION NORTH OF WARM FRONTAL BOUNDARY. TEMPERATURES WILL BE CONFINED INSIDE CLIMO DUE TO DEEP MOISTURE. .LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)...OVERALL...LONGTERM PERIOD STILL LOOKS FAIRLY WET WITH MAX TEMPS SEVERAL DEGREES BELOW GUIDANCE DUE TO CLOUD COVER AND RAIN. AS WITH YESTERDAY...MODELS STILL LOOK TO BE IN PRETTY GOOD AGREEMENT WITH THE OVERALL PATTERN. DRIER AIR STILL PROGGED TO RETURN BY WEDNESDAY NIGHT INTO THURSDAY. SHOWERS AND THUNDERSTORMS SHOULD BE ONGOING TO START THE PERIOD ON SATURDAY NIGHT AS AN UPPER LEVEL SHORTWAVE CONTINUES MOVING THROUGH. INGREDIENTS STILL IN PLACE TO WHERE WILL HAVE TO CONTINUE TO MONITOR THE POTENTIAL FOR A FLOODING THREAT DURING THIS TIME. IT REALLY DEPENDS ON HOW MUCH PRECIP ACTUALLY FALLS THROUGH THE REST OF THE DAY TODAY (FRIDAY) AND UP UNTIL THE START OF THE LONGTERM. ALSO...WITHOUT A DISTINCT FOCUSING MECHANISM IN PLACE...IT IS VERY DIFFICULT TO PINPOINT WHICH AREAS WILL SEE THE GREATEST RAINFALL SINCE THE SHOWERS AND STORMS ARE MORE SCATTERED IN NATURE. UPPER LEVEL SHORTWAVE STILL MOVING THROUGH ON SUNDAY. SO FROM SATURDAY NIGHT THROUGH SUNDAY...SEVERAL ROUNDS OF SHOWERS AND STORMS SHOULD CONTINUE AS SOUNDINGS ARE STILL VERY SATURATED WITH ELEVATED PWS RANGING FROM NEAR 1.75 TO 2 INCHES. PRECIP EFFICIENCY DURING THIS TIME WILL REMAIN HIGH DUE TO WARM LAYER DEPTHS REMAINING BETWEEN 11 AND 12K FEET ALONG WITH MARGINAL CAPE AND WEAK SHEAR. SUNDAY NIGHT INTO EARLY MONDAY ANOTHER SHORTWAVE ADVANCES DOWN OUT OF THE NW. THIS ADVANCING WAVE WILL HELP TO PUSH THIS SLOW MOVING LOW OFF TO OUR NE. FOR THIS REASON...IT LOOKS LIKE THERE SHOULD BE A BREAK IN THE PRECIP FROM SUNDAY NIGHT THROUGH EARLY MONDAY WHILE IN BETWEEN THESE TWO FEATURES. BY MONDAY AFTERNOON MODELS SHOW NEW CONVECTION AND SHOWERS DEVELOPING WITH THE ARRIVAL OF THE AFOREMENTIONED SHORTWAVE. THIS ACTIVITY SHOULD PERSIST INTO THE OVERNIGHT HOURS OF MONDAY AND EARLY TUESDAY MORNING. THEN WE MAY HAVE YET ANOTHER BREAK IN PRECIP FROM LATE TUESDAY MORNING THROUGH AFTERNOON AS SOMEWHAT DRIER AIR STARTS TO WORK ITS WAY IN...BUT THEN WE HAVE THE WEAK COLD FRONT TO DEAL WITH. THE FRONT BEGINS TO MOVE IN BY TUESDAY EVENING INTO WEDNESDAY...ISOLATED SHOWERS AND STORMS ARE EXPECTED WITH THE ARRIVAL OF THE FRONT. WILL CONTINUE ISOLATED SHOWERS AND STORMS ON WEDNESDAY AS THE FRONT CONTINUES TO PUSH THROUGH THE AREA. FINALLY BY THURSDAY...AND MORE SO ON FRIDAY...DRIER AIR LOOKS TO FILTER IN BEHIND THE FRONT WITH A DRY END TO THE WORK WEEK. && .PRELIMINARY POINT TEMPS/POPS...
