AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KNOXVILLE/TRI-CITIES TN
250 PM EDT WED MAY 14 1997

STILL CANNOT RULE OUT WDLY SCTD/SCTD CONVECTION ASSCTD WITH THE FNT
TNT.  STRONG SWLY WINDS CONTINUE TO SLOWLY INCREASE THE SFC DEWPOINTS
ALTHOUGH THEY ARE STILL NOTHING TO WRITE HOME ABOUT.  MOISTURE
CONVERGENCE WL ALSO CONTINUE INCREASING AS PER ADAP AND THE GRIDDED
FCST.  A FEW STORMS MAY CONTAIN SOME BRIEF GUSTY WINDS BUT THE THREAT
WL BE MINIMAL.

THE COLD FNT WL SWING THROUGH AFT MIDNIGHT.  THE WINDS WL STAY UP
ENOUGH BOTH AHEAD OF AND BEHIND THE FNT SO THAT LOWS WL BE MILDER THAN
THEY HAVE BEEN OVER THE PAST FEW NIGHTS.  PC SKIES THROUGH MIDNIGHT
AND THEN MOSTLY CLR WL BE THE RULE.  ANOTHER BREEZY DAY FOR THU.
STRONG CAA WL LKLY BE MODIFIED BY THE STRONG MAY SUN.  TEMPS WL STILL
BE 5 TO 10 DEGS COOLER THAN THIS AFTN'S HIGHS.  I THINK EVEN SW VA WL
BE TOO STABLE AND DRY TO SUPPORT EVEN A DIURNAL AFTN SHRA.  THE MAIN
COLD POOL ALOFT WL STILL BE TO THE NORTH OF SW VA.  INSTABILITY CU WL
LKLY BE ABOUT IT.

EXCEPT FOR SW VA AND THE NRN MTNS SKIES WL BE CLR AREAWIDE FOR THU
NIGHT.  RADIATIONAL COOLING WL BE HINDERED SOMEWHAT BY THE WINDS.
HOWEVER QUITE CHILLY READINGS ARE STILL EXPECTED.  THE BELOW NORMAL
BUT DRY TEMP REGIME CONTINUES ON FRI AS THE ERN TROUGH/WRN RDG
SYNOPTIC PATTERN HOLDS ON.  LOOKS LIKE BY THE WEEKEND THIS PATTERN WL
FINALLY BREAK DOWN AND WE CAN FINALLY ENJOY SOME WARM TEMPS.

GUIDANCE CLOSE THROUGHOUT AND GENERALLY ACCEPTED.
