AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
958 PM EST SAT DEC 15 2007

.SYNOPSIS...
LOW PRESSURE WILL TRACK INTO THE TENNESSEE VALLEY THIS EVENING...AND
THEN TRANSFER ITS ENERGY TO A NEW LOW OFF THE COAST BY SUNDAY
MORNING. GUSTY WINDS ARE EXPECTED AS THE STORM DEPARTS SUNDAY.
HIGH PRESSURE IS FORECAST TO REBUILD EARLY NEXT WEEK. THE NEXT LOW
PRESSURE SYSTEM WILL SLIDE INTO THE OHIO VALLEY LATE THURSDAY AND
FRIDAY.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
PRECIPITATION HAS FINALLY BEGUN TO OVERSPREAD MOST OF THE CWFA. IN
THE LAST HOUR OR SO...SEVERAL REPORTS FROM WEST VIRGINIA AND WESTERN
LOUDOUN COUNTY HAVE COME IN REPORTING THAT SURFACES ARE BEGINNING TO
GLAZE OVER IN THE FREEZING RAIN.

TEMPERATURES IN WESTERN MARYLAND AND THE PANHANDLE OF WEST VIRGINIA
ARE BELOW FREEZING...WITH THE HIGHER TERRAIN WELL BELOW FREEZING AND
IN THE 20S. THE MAIN QUESTION WILL BE WHEN/WHERE THE TEMPS WILL
BEGIN TO RISE OVERNIGHT. BELIEVE AREAS EAST OF THE BLUE RIDGE
MOUNTAINS WILL RISE ABOVE FREEZING OVERNIGHT. THIS IS HANDLED WELL
IN THE CURRENT FORECAST. AREAS WEST OF THE BLUE RIDGE WILL BE A BIT
TRICKIER...BUT THINK THE SW CWFA SHOULD SEE SOME RISING TEMPERATURES
BEFORE THE END OF THE EVENT. THE TEMPS SHOULD REMAIN NEARLY STEADY
IN THE WV PANHANDLE...AND WESTERN MARYLAND. THE ONE EXCEPTION TO THE
RISING TEMPS SHOULD BE THE HIGHER TERRAIN.

OVERALL...THE CURRENT FORECAST HAS EVERYTHING ON TRACK. WILL ONLY BE
MAKING A FEW TWEAKS TO THE TEMPS/DEWPOINTS AND WINDS. EARLIER UPDATE
ENCOMPASSED THE WIND FORECAST FOR SUNDAY INTO MONDAY.

WILL NOT BE MAKING ANY CHANGES TO THE CURRENT WINTER/WIND HEADLINES
IN PLACE.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/...
LOPRES TO MV N OF AREA SUN...TRACKING FAIRLY CLOSE TO CWFA. BEST
PCPN WL BE SHUNTED N/E OF CWFA ELY...AND WLY FLOW SHUD STRT TO SCOUR
OF CLDS. THUS...HV TRIMMED MOST WINTER HEADLINES...ADVY AT 7AM /IF
NOT BEFORE/...AND 1PM IN VLY. WL KEEP WSWRNG IN MTNS AS IS...BASED
ON RDVLPMNT OF SHSN. WNDS SHUD INCR AS STRONG CAA KICKS IN. PROFILES
SUGGEST STRONGEST WNDS SUN NGT...AND THUS WL WAIT ANTHR CYCLE BEFORE
RAISING ANY WND HEADLINES. MAXT NEAR MIDDAY...W/ TEMPS DROPPING OFF
AGN DURING THE AFTN. TOOK BLEND OF GDNC SOLNS.

&&

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
SUNDAY NIGHT AND MONDAY...A MAJOR COASTAL STORM WILL CONTINUE TO
RAPIDLY INTENSIFY SUNDAY NIGHT AS IT HEADS THROUGH NEW ENGLAND. A
STRONG PRESSURE GRADIENT BETWEEN THIS STORM AND HIGH PRESSURE OVER
THE MIDWEST WILL BRING GUSTY WEST-NORTHWEST WINDS TO THE ENTIRE
CWA FOR SUNDAY NIGHT INTO MONDAY. STRONG COLD ADVECTION WILL
COMBINE WITH WRAP AROUND MOISTURE FROM THIS STORM AND THE GREAT
LAKES TO PRODUCE UPSLOPE SNOW SHOWERS ACROSS THE POTOMAC HIGHLANDS
INTO MONDAY MORNING. 12Z NAM/GFS BUFKIT PROFILES SHOW SATURATED
LOW-LEVELS BELOW 3000 FEET UNDERNEATH THE SUBSIDENCE INVERSION.
THE LAYER OF MAXIMUM DENDRITIC SNOW GROWTH IS ALSO LOCATED FROM
JUST ABOVE THE SURFACE UP TO THE SUBSIDENCE INVERSION. THEREFORE...
WE WENT CATEGORICAL WITH THE POPS AND SOME ACCUMULATION IS LIKELY
ACROSS EXTREME WESTERN MARYLAND AND EASTERN WEST VIRGINIA. HIGH
PRESSURE WILL BUILD OVER THE CWA LATER MONDAY ALLOWING FOR WINDS
TO GRADUALLY SUBSIDE AND SNOW SHOWERS ACROSS THE POTOMAC HIGHLANDS
TO SLOWLY DISSIPATE.

TUESDAY THROUGH SATURDAY...HIGH PRESSURE WILL BUILD OVER THE MID-
ATLANTIC FOR TUESDAY BRINGING DRY AND SEASONABLE CONDITIONS. A
WEAK CLIPPER SYSTEM WILL PASS BY TO OUR NORTH FOR WEDNESDAY WITH
LITTLE IMPACT ON THE WEATHER. HIGH PRESSURE WILL BUILD BACK OVER
THE REGION BEHIND THIS SYSTEM...BUT THE NEXT STORM SYSTEM WILL BE
ON ITS HEELS BRINGING A CHANCE FOR PRECIPITATION LATER THURSDAY
AND FRIDAY. AS OF NOW IT LOOKS LIKE THIS WILL BE A RAIN PRODUCER.
WEAK HIGH PRESSURE MAY MOVE IN BEHIND THIS SYSTEM TO START NEXT
WEEKEND.

&&

.AVIATION /03Z SUNDAY THROUGH THURSDAY/...
CIGS/VSBYS ARE MOSTLY MVFR CURRENTLY AND ARE EXPECTED TO BEGIN
DROPPING TO IFR OVERNIGHT. KRMB WILL CONTINUE WITH THE FREEZING
RAIN...WITH THE REMAINDER OF THE TERMINAL SITES SWITCHING OVER
RAIN AFTER MIDNIGHT.

&&

.MARINE...
SCA REMAINS FOR 20 KT IN BLDG SLY FLOW TNGT AND SUN. HOWEVER...A
STRONG PRESSURE GRADIENT BETWEEN THE COASTAL STORM MOVING THROUGH
NEW ENGLAND AND HIGH PRESSURE OVER THE MIDWEST WILL BRING GALE
FORCE WIND GUSTS FROM THE WEST-NORTHWEST LATER SUNDAY AFTERNOON
INTO MONDAY AFTERNOON. A GALE WARNING IS IN EFFECT FROM 4 PM
SUNDAY UNTIL 10 AM MONDAY MORNING. WINDS WILL GRADUALLY SUBSIDE ON
MONDAY AS HIGH PRESSURE DRAWS CLOSER BUT A SMALL CRAFT WINDS ARE
STILL EXPECTED. HIGH PRESSURE WILL BRING TRANQUIL CONDITIONS FOR
THE MIDDLE PART OF THE WEEK AND THE NEXT STORM SYSTEM WILL
APPROACH LATE IN THE WEEK.
