AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
235 PM EDT WED JUN 4 2014

.SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)...CURRENT SURFACE ANALYSIS
SHOWS A WEAK FRONTAL BOUNDARY JUST NORTH OF THE OHIO RIVER...WITH A
VERY WARM AND MOIST AIR MASS OVER THE FORECAST AREA. SATELLITE AND
RADAR IMAGERY REVEAL SOME CONVECTIVE ACTIVITY BEGINNING TO REDEVELOP
OVER THE MID MS RIVER VALLEY...WHICH SHOULD THEN MOVE SOUTHEASTWARD
INTO A VERY UNSTABLE AIR MASS DEVELOPING THIS AFTERNOON OVER THE TN
RIVER VALLEY. WITH A FAIRLY STRONG MID LEVEL WIND FLOW (AROUND 40
TO 45 KT)...EXPECT THIS CONVECTION TO ORGANIZE INTO AN MCS WITH THE
POTENTIAL FOR WIDESPREAD DAMAGING WINDS...AS WELL AS LARGE HAIL...
LOCALLY HEAVY RAINFALL...AND AN ISOLATED TORNADO. RIGHT NOW...IT
APPEARS THAT THIS POTENTIAL MCS SHOULD BEGIN TO AFFECT THE CUMBERLAND
PLATEAU AROUND 00Z (8 PM EDT)...AND THEN THE REST OF THE FORECAST
AREA AFTER SUNSET.

MODELS THEN INDICATE THAT THE FRONTAL BOUNDARY WILL SLOWLY DRIFT
SOUTHWARD THROUGH THE FORECAST AREA ON THURSDAY...WITH ANOTHER MCS
POSSIBLY FORMING AROUND THE OZARKS REGION THURSDAY AFTERNOON AND
THEN MOVING SOUTHEASTWARD ACROSS THE TN RIVER VALLEY. WHILE THE
MODELS INDICATE THAT THIS FRONTAL BOUNDARY WILL MOVE AS FAR SOUTH AS
THE SOUTHERN TN BORDER...THINK THAT IT WILL LIKELY BECOME QUASI-
STATIONARY SOMEWHERE AROUND THE MIDDLE OF THE FORECAST AREA SINCE
THE UPPER-LEVEL FLOW APPEARS TO BECOME PARALLEL TO THE BOUNDARY.
THUS...WILL KEEP A MENTION OF SCATTERED CONVECTION FOR MOST OF THE
FORECAST AREA THROUGH FRIDAY NIGHT. AS FOR TEMPS...GFS AND NAM
GUIDANCE NUMBERS ARE IN GENERAL AGREEMENT THROUGH FRIDAY NIGHT...BUT
WILL TREND TOWARDS THE SLIGHTLY WARMER NAM NUMBERS SINCE THE FRONTAL
BOUNDARY IS EXPECTED TO REMAIN FARTHER NORTH THAN THE MODELS WOULD
SUGGEST.

.LONG TERM (SATURDAY THROUGH WEDNESDAY)...A FRONTAL BOUNDARY WILL
REMAIN STATIONARY ACROSS THE SOUTHERN APPALACHIANS AND TENNESSEE
VALLEY THROUGH MUCH OF THE PERIOD. THE ATMOSPHERE SHOULD BE ABLE TO
PRODUCE THE NECESSARY AMOUNT OF INSTABILITY FOR SCATTERED SHOWERS
AND THUNDERSTORMS EACH DAY ACROSS THE REGION. THERE IS A POSSIBILITY
THAT THE CONVECTION COULD BE A LITTLE MORE ORGANIZED AROUND THE
SUNDAY THROUGH MONDAY TIME FRAME AS THE MODELS SHOW A SLIGHTLY MORE
AMPLIFIED UPPER LEVEL TROUGH BUILDING ACROSS THE REGION. THEREFORE
PROBABILITY OF PRECIPITATION MAY NEED TO BE ADJUSTED A LITTLE HIGHER
EARLY IN THE NEW WEEK. TRIMMED A COUPLE DEGREES OFF SUGGESTED HIGH
TEMPERATURES DURING THE LONG TERM PERIOD.
