Severe Thunderstorm Warning 104, NWS Morristown, TN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
310 PM EDT SAT JUN 7 2008

.SHORT TERM...(TONIGHT THROUGH MONDAY)...DEFINITELY SEEING MORE
COVERAGE OF TSRA THIS AFTERNOON. CUMULUS CLOUDS DEVELOPED GENERALLY
OVER THE HIGHER TERRAIN...WITH NO INDICATIONS AT ALL OF ANY
OUTFLOW BOUNDARIES. HOWEVER...AT MID AFTERNOON SHOWERS AND BRIEFLY
STORMS WERE FORMING OVER MUCH OF THE SRN MTNS...SMOKY MTNS AND ERN
PARTS OF THE CUMBERLAND PLATEAU. MOVEMENT APPEARED TO BE NE AT 10
TO 15 MPH. WATCHING THE STRONGER STORMS FOR POSSIBLY PULSING TO
NEAR SEVERE STRENGTH. APPEARS THAT BOTH TRI AND OQT SHOULD AT LEAST
TIE THE RECORD HIGHS FOR TODAY (93 DEGREES).

FORECAST GRIDS LOOKED GOOD FOR TONIGHT WITH 20 TO 30 PERCENT CHANCE
POPS ACROSS THE BOARD. STAYED CLOSE TO GFS MINS.

FOR SUNDAY...DECIDED TO ADD SLIGHT CHANCE POPS FOR THE AFTERNOON
HOURS FOR AT LEAST THE ERN MTNS...AS I DONT SEE HIGH PRESSURE
RIDGE COMPLETELY SUPPRESSING CONVECTION. WILL LET MIDNIGHT SHIFT
PONDER ADDING LOW POPS ELSEWHERE FOR SUNDAY...AND ANY NEED FOR
EVENING POPS. KEPT NEAR RECORD HIGH WORDING OUT OF TYS AND CHA
GROUPS ...SINCE RECORD HIGHS FOR CHA AND TYS FOR 6/8 ARE 100
DEGREES. PERSISTENCE ON MINS WAS CLOSE TO GFS VALUES.

FOR MONDAY...EXPECT A LITTLE MORE COVERAGE OF TSRA WHICH PREVIOUS
FORECAST GRIDS ALREADY TRENDED TOWARD. MAX TEMPS SHOULD BE 1 TO 2
DEGREES LOWER THAN SUNDAY MAX TEMPS. LITTLE CHANGES MADE TO
PREVIOUS GRIDS FOR MONDAY.

.LONG TERM...(MONDAY NIGHT THROUGH SATURDAY)...RIDGE WILL CONTINUE
TO SLIP EAST TO THE WESTERN ATLANTIC EARLY IN THE PERIOD AS SHORT
WAVE AND ASSOCIATED WEAK COOL FRONT BUILDS SLOWLY SOUTH AND EAST
TOWARD THE SOUTHERN APPALACHIANS. USING ECMWF MODEL FRONTAL TIMING
WOULD BE LATE TUESDAY INTO WEDNESDAY AND STAYED WITH HIGHEST CHANCE
POPS DURING THIS PERIOD. HOWEVER SOME MEDIUM CHANCE POPS WILL BE
MAINTAINED IN THE TERRAIN AREAS WITH SLIGHT CHANCE IN THE GREAT
VALLEY THROUGH THE REMAINDER OF THE EXTENDED FORECAST AS MOISTURE
AND INSTABILITY PROGGED TO BE SUFFICIENT FOR WIDELY SCATTERED
CONVECTION IN THE VALLEY WITH SCATTERED DEVELOPMENT IN THE HIGHER
TERRAIN. WENT QUITE CLOSE TO MEX MOS TEMP GUIDANCE THROUGHOUT THE
PERIOD.
