AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
338 PM EST WED MAR 15 2006

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...HIGH PRESSURE REMAINS
IN CONTROL OF THE WEATHER ACROSS THE SE CONUS THIS
AFTERNOON...RESULTING IN CLEAR SKIES ACROSS THE FORECAST AREA. MAIN
SHORT TERM CONCERNS FOR TONIGHT REVOLVE AROUND MIN TEMPERATURES AND
FROST POTENTIAL.

TONIGHT...HIGH PRESSURE WILL BUILD OVERHEAD AND ASIDE FROM SOME
CIRRUS DRIFTING INTO THE AREA TOWARD MORNING THU...GENERALLY CLEAR
SKIES ARE EXPECTED. WITH MOSTLY CLEAR SKIES AND LIGHT WINDS ACROSS
THE AREA...EXPECT AN EXCELLENT RADIATIONAL COOLING NIGHT. LOW
TEMPERATURES SHOULD BOTTOM OUT IN THE MID 30S AWAY FROM THE
IMMEDIATE COAST. ALTHOUGH HUMIDITY RECOVERY IS NOT ANTICIPATED TO BE
TOO GREAT OVERNIGHT...IT SHOULD BE SUFFICIENT FOR SCATTERED FROST
ACROSS INTERIOR ZONES...THEREFORE WILL ISSUE A FROST ADVISORY FOR
ALL INTERIOR ZONES. ACROSS COASTAL ZONES WILL MENTION PATCHY FROST
AWAY FROM THE COAST.

THU AND THU NIGHT...HIGH PRESSURE WILL SLIDE OFF THE SE COAST...AS A
FRONTAL BOUNDARY BEGINS TO APPROACH THE REGION FROM THE WEST. EXPECT
AN INCREASE IN MID AND HIGH CLOUD COVER AS SYSTEM APPROACHES...AND
WILL BEEF UP SKY COVER A BIT...BUT STILL ANTICIPATE A PARTLY SUNNY
DAY AND PARTLY CLOUDY NIGHT. WILL KEEP THE FORECAST DRY...AS THE
AIRMASS WILL REMAIN TOO DRY...AND WILL LACK ANY SUFFICIENT UPPER
SUPPORT TO PRODUCE ANY RAINFALL. HIGHS THU WILL TOP OUT AROUND 70
DEGREES...WITH LOWS THU NIGHT IN THE UPPER 40S TO AROUND 50.
&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...MEDIUM RANGE GUIDANCE
REMAINS IN GOOD AGREEMENT EARLY IN THE EXTENDED PERIOD...THEN
DIVERGE BY THE END OF THE EXTENDED PERIOD...OFFERING A WIDE ARRAY OF
SOLUTIONS. DESPITE THE VARYING SOLUTIONS THERE ARE SOME DETAILS THAT
ARE HANDLED SIMILARLY.

A COLD FRONT IS EXPECTED TO PUSH THROUGH THE REGION EARLY FRI...WITH
HIGH PRESSURE SETTLING INTO THE AREA FRI NIGHT THROUGH SAT NIGHT.
WILL KEEP THE FORECAST DRY FRI THROUGH SAT NIGHT...AS AIRMASS WILL
REMAIN TOO DRY TO SUPPORT ANY RAINFALL. DESPITE HANDLING FEATURES A
BIT DIFFERENTLY...ALL MODELS AGREE THAT LOW LEVEL MOISTURE WILL BE
ON THE INCREASE SUN THROUGH TUE...AND HINT THAT A COLD AIR DAMMING
PATTERN MAY TAKE HOLD ACROSS THE AREA. WILL MAINTAIN CHC POPS SUN
THROUGH TUE ACROSS THE REGION AND WON/T GET TO CUTE WITH TIMING
DETAILS GIVEN LARGE DIFFERENCES FROM ONE MODEL SOLUTION TO THE
NEXT. BOTH THE 00Z ECMWF AND 00Z GFS SUGGEST THAT THE UNSETTLED
WEATHER WILL COME TO AN END TUE NIGHT AND WED...AS WINDS SHIFT TO
THE WEST AND HELP TO DRY THINGS OUT. THEREFORE WILL KEEP FORECAST
DRY TUE NIGHT AND WED. TEMPERATURES THROUGH THE EXTENDED ARE
EXPECTED TO REMAIN WELL BELOW CLIMO. THE EXCEPTION WILL BE ON
FRI...WHERE GOOD DOWNSLOPE WIND FLOW FOLLOWING FRONTAL PASSAGE
SHOULD ALLOW TEMPS TO CLIMB INTO THE MID 70S ACROSS THE AREA.
&&

.MARINE...
WINDS BECOMING LIGHT AND VRBL ACROSS THE GEORGIA WATERS LATE THIS
AFTERNOON AND SEA BREEZE INDUCED SWLY COMPONENT SHOWING UP AT SOME
OF THE SOUTH CAROLINA BEACHES WITH A NW FLOW FURTHER OFF THE CAROLINA
COAST. WE WILL CONTINUE PREVIOUS PREVIOUS TRENDS WITH DECREASING
WINDS/SEAS AND VERY LIGHT WINDS BY THU MORNING...THEN A SHIFT TO A
SLY COMPONENT AS THE HIGH SHIFTS WELL OFF THE COAST DURING THE DAY.
SW TO WNW LLJ PROGRESSION THU NIGHT AND FRI. HIGHER GUSTS SHOULD MIX
OUT OVER LAND ON FRI AND WE HELD DOWN SPEEDS OVER THE WATERS ON FRI.

THERE WILL BE AN INITIAL SURGE OF NNE WINDS SAT THEN MORE IMPRESSIVE
SFC WEDGING SETTING UP ON SUN AND MON. TRICKY FCST AT THIS STAGE BUT
TRENDS INDICATE SCA CONDITIONS DEVELOPING SUN AND CONTINUING INTO
MON. A PINCHED GRADIENT SITUATION LOOKS LIKELY FOR AT LEST PARTS OF
OUR FORECAST WATERS.
&&

.AVIATION...
WINDS CONTINUE TO DIMINISH THIS AFTERNOON AND WILL GO CALM/LIGHT
OVERNIGHT. VFR FORECAST WITH AN INCREASE IN HIGH CLOUDS THURSDAY
MORNING.
&&

.FIRE WEATHER...DRY AIRMASS WILL CONTINUE TO KEEP RH VALUES NEAR
CRITICAL LEVELS DURING THE AFTERNOON HOURS THU...AND WILL HEADLINE
NEAR CRITICAL RH VALUES IN THE FIRE WEATHER FORECAST.
