AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
320 PM EST SAT FEB 9 2013

.SHORT TERM...(TONIGHT AND SUNDAY)...HIGH PRESSURE WILL RETREAT
TONIGHT. A LOW PRESSURE SYSTEM WILL TRACK OUT OF THE PLAINS TOWARD
THE WESTERN GREAT LAKES REGION ON SUNDAY...PUSHING A COLD FRONT
TOWARD OUR AREA.  LOW LEVEL JET WILL INCREASE FROM THE SOUTH ON
SUNDAY...AND WHILE SET UP DOES NOT LOOK IDEAL AT THIS POINT THERE
DOES APPEAR TO BE SOME THREAT OF MOUNTAIN WAVE HIGH WINDS IN THE
HIGHER TERRAIN AND FOOTHILLS BY LATE SUNDAY.  WILL ISSUE A HIGH WIND
WATCH FOR NOW...WITH EITHER A WIND ADVISORY OR WARNING LIKELY TO BE
ISSUED LATER.  CLOUDS WILL INCREASE TONIGHT AND SUNDAY AS MOISTURE
INCREASES.  RAIN WILL START TO MOVE IN SUNDAY AFTERNOON...SO WILL
HAVE HIGHEST POPS SOUTHWEST ZONES.

.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)... A STRONG UPPER-LEVEL
STORM SYSTEM WILL IMPACT THE REGION EARLY THIS WEEK...BRINGING SOME
LOCALLY HEAVY RAINFALL AND STRONG GRADIENT WINDS TO THE AREA LATE
SUNDAY AFTERNOON AND SUNDAY NIGHT. A BOUNDARY WILL MOVE INTO THE
REGION LATE SUNDAY AND COMBINE WITH A STRONG LOW-LEVEL 850 MB JET
THAT ROTATE OVER THE REGION THAT EVENING... PROVIDING THE LIFT FOR
NUMEROUS SHOWERS IN THE MOIST GULF AIR MASS. MODELS ARE IN GOOD
AGREEMENT WITH THE TIMING OF THE PRECIP SHOWING IT MOVING INTO THE
WESTERN ZONES AFTER 18-21Z AND QUICKLY EXPANDING OVER THE ENTIRE
FORECAST AFTER 00Z...BEFORE BEGINNING TO TAPER OFF MONDAY AS THE
BOUNDARY SAGS SOUTH. PWATS ARE RUNNING UP TO 1.5 INCHES ON SUNDAY
NIGHT WHICH WILL ALLOW FOR LOCALLY HEAVY RAINFALL AND LOCALIZED
FLOODING CONCERNS IN AREAS THAT RECEIVE HEAVIER BURSTS OF RAINFALL
AND EXPERIENCE TRAINING CELLS. HOWEVER...GIVEN THAT THIS SHOULD NOT
BE A LONG DURATION HEAVY RAINFALL EVENT...WITH GENERALLY 1 TO 2.5
INCHES /WITH SOME LOCALLY HIGHER AMOUNTS/...OVER A 12-18 HOUR
PERIOD...AM NOT EXPECTING ANY SIGNIFICANT FLOODING CONCERNS... AND
THUS WILL HOLD OFF ON ANY HYDROLOGICAL WATCHES FOR NOW.

THE MAIN CONCERN SUNDAY NIGHT MAY VERY WELL BE AFOREMENTIONED
GRADIENT WINDS ASSOCIATED WITH THE 60+ KT LOW-LEVEL JET THAT WILL
ROTATE OVER THE REGION. THIS MAY LEAD TO ADVISORY LEVEL WINDS IN THE
VALLEY AND EVEN STRONGER WINDS IN THE HIGHER TERRAIN AND
FOOTHILLS...WHERE A MOUNTAIN WAVE EVENT WILL BE POSSIBLE GIVEN THE
STRONG SOUTHEAST FLOW AHEAD OF THIS SYSTEM. AS A RESULT...WE HAVE
ISSUED A HIGH WIND WATCH FOR THESE AREAS FROM 20Z ON SUNDAY THROUGH
09Z MONDAY MORNING.

WITH THE BOUNDARY SAGGING SOUTH OF THE AREA...PRECIP WILL TAPER OFF
SIGNIFICANTLY MONDAY AFTERNOON AND NIGHT...AND SOME CLEARING ACROSS
THE NORTHERN ZONES MAY EVEN OCCUR. A SECOND UPPER-WAVE WILL THEN
MOVE TOWARD THE REGION TUESDAY AND BRING INCREASING CHANCES FOR SOME
SHOWERS TUESDAY NIGHT INTO WEDNESDAY...BEFORE CLEARING OUT LATER
THAT NIGHT. AN UPPER-RIDGE WILL PROMOTE PLEASANT CONDITIONS FOR
THURSDAY /VALENTINES DAY/...BEFORE THE NEXT UPPER-WAVE APPROACHES
THE REGION FRIDAY INTO THE WEEKEND. WITH COLDER AIR IN PLACE SOME
SNOW SHOWERS WILL BE POSSIBLE ALONG WITH SOME RAIN...BUT GIVEN THE
HIGH MODEL SPREAD ON THE TIMING/TRACK OF THIS SYSTEM HAVE NOT GONE
ABOVE 20-30 POPS FOR NOW AND WILL WAIT FOR BETTER CONTINUITY.
