Area forecast discussion, Jan 29, 2:50 PM EST, 37 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
250 PM EST TUE JAN 29 2008
.SHORT TERM (TONIGHT AND WEDNESDAY)...STRONG COLD FRONT CONTINUES TO
APPROACH THE SOUTHERN APPALACHIAN REGION FROM THE WEST. VERY STRONG
TEMP GRADIENT ASSOCIATED WITH THIS FRONT WITH TEMPS IN 60S PRECEDING
FRONT AND IN THE TEENS BEHIND. ALSO STRONG WINDS NOTED NEAR FRONT.
AS SUCH...WILL ISSUE WIND ADVISORY FOR ENTIRE FORECAST AREA FOR LATE
THIS AFTERNOON THROUGH TONIGHT. LOW-LEVEL JET WITH NEAR 50 KNOT
WINDS AT 850 MB WILL BE AVAILABLE TO BE TRANSPORTED TO THE SURFACE
WITH ANY CONVECTION THAT DEVELOPS. THUS ISOLATED DAMAGING WINDS
CANNOT BE RULED OUT. VERY LITTLE INSTABILITY AVAILABLE WITH THIS
SYSTEM FOR OUR AREA...BUT DYNAMICS/LIFT MAY BE STRONG ENOUGH TO
OVERCOME LACK OF INSTABILITY FOR A FEW THUNDERSTORMS TO DEVELOP...
AND WILL CONTINUE TO MENTION IN ZONES. BASED ON GFS TIME-HEIGHTS...
MOISTURE WILL CUT OFF ABRUPTLY BEHIND FRONT AND MOST OF THE MOISTURE
SHOULD BE GONE AS THE COLD AIR ARRIVES AND SNOW CHANCES APPEAR
LIMITED. OVERALL...DID NOT MAKE ANY MAJOR CHANGES TO PREVIOUS
FORECAST/GRIDS.
.LONG TERM (WEDNESDAY NIGHT THROUGH TUESDAY)...HIGH PRESSURE SHOULD
BE CENTERED OVER THE REGION ON WEDNESDAY NIGHT...WITH A LOW PRESSURE
SYSTEM DEVELOPING OVER THE SOUTHERN PLAINS. THIS LOW PRESSURE SYSTEM
WILL QUICKLY MOVE INTO THE TN RIVER VALLEY BY THURSDAY EVENING...
WITH STRONG SOUTHEASTERLY WINDS PROGGED TO DEVELOP OVER THE
MOUNTAINS ALONG WITH A STABLE BOUNDARY LAYER. THIS SCENARIO COULD
RESULT IN THE DEVELOPMENT OF MOUNTAIN WAVES PRODUCING DAMAGING WINDS
IN THE FOOTHILLS. IN ADDITION...THESE DOWNSLOPING SOUTHEASTERLY WINDS
WILL ALSO LIKELY SIGNIFICANTLY DECREASE THE RAINFALL AMOUNTS ACROSS
THE CENTRAL AND NORTHERN VALLEY AREAS...AND ALSO CONTRIBUTE TO SOME
ADIABATIC WARMING IN THESE SAME AREAS. WILL HAVE TO CLOSELY MONITOR
THESE POSSIBILITIES AS THIS SYSTEM EVOLVES LATER THIS WEEK.
OVERALL...GFS AND ECMWF MODELS APPEAR TO BE IN GOOD AGREEMENT
THROUGHOUT THE EXTENDED PERIOD...AND INDICATE A PROGRESSIVE PATTERN
WITH ANOTHER STRONG SYSTEM TO AFFECT THE FORECAST AREA BY EARLY NEXT
WEEK. THIS NEXT LOW PRESSURE SYSTEM IS PROGGED TO BRING A COLD FRONT
WITH STRONG UPPER-LEVEL DYNAMICS INTO THE FORECAST AREA BY MONDAY
NIGHT INTO TUESDAY. WITH TEMPS REMAINING ABOVE NORMAL THROUGH THE
WEEKEND AND INTO EARLY NEXT WEEK...THINK THAT THE LOCAL AIR MASS
WILL HAVE SEVERAL DAYS TO MOISTEN ENOUGH TO PRODUCE AN UNSTABLE AIR
MASS AHEAD OF MONDAY NIGHTS FRONT. THUS...WILL MENTION TSTORMS AND
THINK THAT THIS SYSTEM WILL NEED TO BE MONITORED FOR POSSIBLE SEVERE
WEATHER ACROSS THE TN RIVER VALLEY.
