AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
300 AM EST THU MAR 1 2007
.SHORT TERM (TODAY THROUGH SATURDAY NIGHT)... SHOWERS AND
THUNDERSTORMS HAVE DEVELOPED IN WEST TN AND NRN MS...ASSOCIATED
WITH THE NOSE OF THE UPPER JET AND STRONG THETA-E ADVECTION JUST
NORTH OF THE SURFACE WARM FRONT. THIS CONVECTION WILL BEGIN TO
AFFECT OUR WESTERN COUNTIES BY 10Z. EXPECT THAT THERE WILL BE TWO
MAIN SURGES OF PRECIP TODAY. THE FIRST WILL SOME DURING THE DAY AS
THE 850 MB JET STRENGTHENS AND ADVECTS WARM MOIST AIR OVER THE
SURFACE WARM FRONT. THE CONVECTION WILL BE ELEVATED DURING THE
DAY...AND THUS LESS LIKELY TO PRODUCE WIDESPREAD SEVERE
WEATHER...THOUGH SOME HAIL AND ISOLATED STRONG WIND GUSTS WILL BE
POSSIBLE. THE WARM FRONT WILL PUSH FROM SOUTH TO NORTH ACROSS THE
AREA LATE THIS AFTERNOON...CAUSING SURFACE DEWPOINTS TO RISE
RAPIDLY INTO THE 50S. A SECOND ROUND OF PRECIP WILL COME WITH THE
PASSAGE OF THE SURFACE COLD FRONT BETWEEN 00Z AND 06Z. THESE STORMS
WILL LIKELY BE IN THE FORM OF A SQUALL LINE AND WILL BE SURFACE-
BASED...AND THUS MORE LIKELY TO PRODUCE DAMAGING WIND GUSTS. AN
ISOALTED TORNADO CANNOT BE RULED OUT IN THE SOUTHERN VALLEY. NAM
SBCAPE IN THE EVENING REACHES 500-700 J/KG...THOUGH THE SREF MEAN
SHOWS LESS INSTABILITY. HOWEVER NOT MUCH INSTABILITY WILL BE NEEDED
FOR SEVERE WX GIVEN THE STRONG DYNAMICAL FORCING. WILL ISSUE AN SPS
FOR THE SEVERE THREAT. THE WIND ADVISORY WILL BE CONTINUED FOR THE
MOUNTAINS. THE COLD FRONT CLEARS THE AREA BY 09Z AND WILL END ALL
POPS AROUND 12Z FRIDAY.
WITH THE CLOSED LOW REMAINING OVER THE GREAT LAKES REGION AND THE
FLOW ALOFT REMAINING WEST TO SOUTHWEST OVER OUR AREA...A STRONG
SURGE OF COLD AIR DOES NOT FOLLOW THE FRONT...SO TEMPS WILL REMAIN
ABOVE NORMAL FOR FRIDAY. A TROUGH ROTATES AROUND THE LOW AND WILL
CROSS OUR AREA ON SATURDAY/SATURDAY NIGHT. MOISTURE REMAINS LIMITED
WITH THE SYSTEM SO WILL KEEP POPS IN THS SLIGHT TO LOW CHANCE RANGE.
INCREASING COLD ADVECTION SATURDAY NIGHT MAY DROP TEMPS ENOUGH FOR A
CHANGE TO SNOW IN THE NORTH BEFORE THE PRECIP ENDS.
.LONG TERM (SUNDAY THROUGH WEDNESDAY)...EASTERN STATES UPPER TROF
MOVES OFFSHORE BY 12Z MONDAY ALLOWING FOR AN END TO THE
FLURRIES/SNOW SHOWERS ACROSS THE HIGHER TERRAIN OF SOUTHWEST
VIRGINIA AND NORTHEAST TENNESSEE SUNDAY MORNING. UPPER RIDGING
BECOMES SUPPRESSED SOUTH INTO THE SUBTROPICS BY 00Z TUESDAY WITH
ZONAL FLOW DEVELOPING. WEAK BACKDOOR FRONT TRIES TO DROP INTO THE
SOUTHERN APPALACHIANS BY WEDNESDAY WITH LITTLE IMPACT AS LOW LEVEL
FLOW ACROSS SOUTHEAST STATES REMAINS EAST TO NORTHEASTERLY. STAYED
RELATIVELY CLOSE TO SUGGESTED MEX MOS TEMP GUIDANCE DURING LONG
TERM.
