AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
147 PM EDT SUN MAR 8 2009

.SYNOPSIS...
HIGH PRESSURE CENTERED OVER THE SOUTHEAST U.S. WILL BRING ONE MORE
MILD AND BREEZY DAY TODAY. A WEAK COLD FRONT WILL APPROACH THE
REGION TONIGHT AND BRING SHOWERS TO THE MOUNTAINS. THE WEAK FRONT
WILL MOVE THROUGH THE AREA MONDAY MORNING...FOLLOWED BY A STRONGER
COLD FRONT ON WEDNESDAY. MUCH COOLER HIGH PRESSURE WILL BUILD INTO
THE AREA TOWARD THE END OF NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
MORNING UPDATE WILL REFLECT BASICALLY A TWEAK TO TEMPERATURE...DEW
POINT...WIND AND SKY COVER TRENDS IN THE GRIDDED DATABASE.
FORECAST RECORD HIGHS STILL LOOK ON TRACK FOR PARTS OF THE
AREA...WITH A GRADUAL INCREASE IN CLOUD COVER OVER MAINLY WESTERN
PARTS OF THE AREA IN THE AFTERNOON.

PREVIOUS DISCUSSION...
MSAS SHOWS SFC HIGH PRESSURE REMAINS CENTERED OFF THE SE U.S. COAST.
MEANWHILE...WATER VAPOR SHOWS THE UPPER RIDGE HOLDING STRONG ACROSS
THE SOUTHEAST...BUT WITH SHORT WAVE ENERGY MOVG ACROSS THE UPPER
GREAT LAKES REGION FLATTENING THE RIDGE TO THE NORTH. THIS IS
BRINGING A SWATCH OF HIGH CLOUDS ACROSS THE AREA OVERNIGHT. THIS IS
HELPING TO HOLD LOW TEMPS UP OVERNIGHT ALONG WITH GUSTY SW SFC
WINDS. SOME RECORD HIGH MINIMUM TEMPS ARE LIKELY...THOUGH WILL HAVE
TO WAIT TILL MIDNIGHT TONIGHT TO MAKE THEM OFFICIAL. A PNS WILL BE
ISSUED IF ANY OF THE RECORDS FOR WARMEST MIN TEMPS SURVIVES TO
SUNUP TODAY. THE SHORT WAVE TO OUR NORTH WILL EXIT ACROSS NEW
ENGLAND LATER TODAY...WHILE THE STRONG SHORT WAVE OVER THE MIDWEST
CONTINUES TO PLOW INTO THE RIDGE. THINKING THAT THIS WILL ACTUALLY
BUILD THE RIDGE OVER THE AREA FOR A SHORT TIME TODAY...AND MOST OF
THE THICKER CLOUDINESS WILL REMAIN TO OUR NORTH AND WEST. FOR THIS
REASON...I HAVE KEPT THE HIGH TEMPS TODAY ABOVE GUIDANCE. SOME
MORE RECORD HIGHS WILL BE THREATENED... PARTICULARLY DANVILLE
WHERE TEMPS SHOULD BE THE WARMEST TODAY.

THE STRONG SHORT WAVE CURRENTLY IN THE MIDWEST...MOVES UP OVER THE
RIDGE TONIGHT AND WILL PUSH A WEAK COLD FRONT THROUGH THE REGION.
BECAUSE OF WESTERLY WINDS AHEAD OF THE FRONT...SHOWERS SHOULD BE
CONFINED TO THE MTNS. HAVE KEPT SOME LIKELY POPS ALONG THE WESTERN
SLOPES IN SE WV...OTHERWISE CHC POPS ELSEWHERE. FINALLY...FAIRLY
STRONG SUBSIDENCE BEHIND THE SHORT WAVE WILL BRING STRONG WINDS
BEHIND THE FRONT LATE MONDAY NIGHT. WIND GUSTS MAY APPROACH ADVISORY
CRITERIA OF 40 KNOTS IN THE HIGH ELEVATIONS TOWARD MORNING.

THE FRONTAL PASSAGE WILL BRING CLOUDS TO THE REMAINDER OF THE CWA.
THESE CLOUDS...IN ADDITION TO FRONTAL MIXING SHOULD KEEP
TEMPERATURES IN THE 50S MOST LOCATIONS TONIGHT.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY/...
FRONTAL BOUNDARY WILL BE AROUND THE BLUE RIDGE AROUND 12Z MONDAY.
WITH LINGERING LOW LEVEL MOISTURE AND WEAK UPSLOPE...ADDED LOW
POPS TO THE MOUNTAIN EMPIRE...GRAYSON HIGHLANDS AND WESTERN NORTH
CAROLINA HIGH COUNTY. THESE SHOWERS SHOULD BE GONE BY 15Z MONDAY.
WITH WESTERN WINDS AND SUBSIDENCE ACROSS THE REST OF THE
AREA...ONLY CLOUDY SKIES ARE EXPECTED MONDAY MORNING. INTO MONDAY
AFTERNOON...HIGH PRESSURE WILL BE CROSSING THE APPALACHIAN
MOUNTAINS WHILE THE FRONTAL BOUNDARY GETS PUSHED TO THE SOUTH.
TOUGH CALL ON TEMPERATURES MONDAY AFTERNOON AS INCREASE SUN ANGLE
AND DOWNSLOPING NORTHWESTERLY WINDS COUNTER ACT COLD AIR
ADVECTION. IF THE DAY STARTS OFF WARM AS NAM/MAV GUIDANCE IS
SUGGESTING...MAV MOS NUMBERS LOOK REASONABLY...ESPECIALLY WITH NO
RAIN FROM THE FRONT IN THE EAST. IN THE WEST...COLD AIR ADVECTION
MAY WIN OUT WITH THE AID OF MORE CLOUD COVER IN THE MORNING. WINDS
COULD ALSO BE AN ISSUE MONDAY MORNING ALONG AND WEST OF THE BLUE
RIDGE. PRESSURE RISE OF 5-7MB/6 HRS...STRONG SUBSIDENCE AND A 50+
KT LOW LEVEL JET COULD BRING ADVISORY WINDS TO THE MOUNTAINS...
ESPECIALLY RIDGES ABOVE 3000 FEET. FOR NOW...WILL ONLY HIGHLIGHT
IN HWO.

MONDAY NIGHT INTO TUESDAY...HIGH PRESSURE WILL WEDGE DOWN THE MID
ATLANTIC COAST. THIS WEDGE WILL INITIALLY BE DRY BUT BY 12Z
TUESDAY...OVERRUNNING MOISTURE AND ISENTROPIC LIFT WILL BRING
LOWERING CLOUDS AND A CHANCE FOR LIGHT RAIN TO AREAS ALONG AND WEST
OF THE BLUE RIDGE. TUESDAY AFTERNOON...EASTERLY WINDS WILL CONTINUE
THE CHANCE FOR LIGHT RAIN/DRIZZLE ALONG THE BLUE RIDGE WHILE
DOWNSLOPE DRYING OCCURS IN SOUTHEASTERN WV. MODELS DIFFERING ON
WHETHER THE WEDGE WILL BREAK TUESDAY NIGHT OR NOT. WITH IT BEING
EARLY IN THE CLIMATIC SPRING...THINK THE NAM HAS A GOOD HANDLE ON
KEEPING THE WEDGE IN PLACE THROUGH TUESDAY NIGHT...BUT SOME EROSION
IS POSSIBLE IN THE WEST AND SOUTH AS SOUTHWESTERLY JET INCREASES
OVER THE AREA TOWARD SUNRISE WEDNESDAY. ANY EVIDENCE OF THE WEDGE
WILL BE GONE BY LATE WEDNESDAY MORNING AS A COLD FRONT APPROACHES
FROM THE WEST. THIS FRONT WILL SLOWLY MOVE ACROSS THE AREA
WEDNESDAY...POSSIBLY WEDNESDAY NIGHT...TO HAVE AN INCREASE IN POPS.

TEMPERATURES TUESDAY WILL BE COOLER THAN THIS PAST WEEKEND BUT SHOULD
REMAIN ABOVE NORMAL BY 5 OR SO DEGREES. WEDNESDAYS TEMPERATURES WILL
BE A CHALLENGE IF PREFRONTAL RAIN AND CLOUDS ARE DELAYED. IF THE
RAIN COMES IN DURING THE MORNING...TEMPERATURES WILL LIKELY BE IN
THE UPPER 50S TO MID 60S. IF IT IS DELAYED...TEMPERATURES COULD BE
IN THE MID 60S TO MID 70S.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
WEDNESDAY FIGURES TO BE ANOTHER WARM DAY AHEAD OF A COLD FRONT
MOVING THROUGH THE OHIO VALLEY. WITH THE UPPER SUPPORT PASSING
THROUGH THE GREAT LAKES...DID DELAY ITS PROGRESSION 6-12 HRS. STRONG
DOWNSLOPE COMPONENT MAY ALSO ERODE SHWRS AS THEY TRY TO PENETRATE NEW
RIVER VALLEY AND PIEDMONT. DID GO ABV MEX THIS DAY ACROSS THE BOARD.
ALSO...COLD AIR ARRIVES TO QUICK WED NIGHT...SO DITTO FOR TEMPS THAT
PERIOD. FRONT THEN SLOWS AND STALLS SOUTH OF US...AS COLDER AIR
SEEPS SOUTH ON NORTHERLY AND EASTERLY COMPONENT AS HIGH PRESSURE
SLIDES ACROSS THE GREAT LAKES TO THE MIDDLE ATLANTIC BY FRIDAY. CLDS
WILL PROBABLY PERSIST WITH PRECIP SLT CHC MAINLY SOUTH FOR NOW THURSDAY
EARLY FRIDAY. NUDGED TOWARDS THE ECMWF WHICH IS A DRIER MORE
SUPPRESSED SOLUTION FOR LATE NEXT WEEK AND WEEKEND.

LOOKING PAST THE LONG RANGE...INDICATIONS THAT WINTER TRIES TO MAKE
A RETURN WEEK OF MAR 15. REX BLOCK OVER EASTERN CANADA FEATURING A
WESTERN ORIENTED NEG NAO AND POLAR VORTEX OVER SE CANADA MAY
DELIVER SLICES OF BELOW NORMAL AIR THROUGH THE WEEK.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
VFR CONDITIONS WILL CONTINUE THROUGH ROUGHLY 04Z ACROSS THE ENTIRE
AREA. AFTER 04Z...THE INFLUENE OF A COLD FRONT MOVING INTO THE
AREA WILL BRING SOME MVFR CIGS INTO THE SE WV MOUNTAINS ALONG WITH
A BROKEN LINE OF SHOWERS ALONG THE COLD FRONT. AN ISOLATED
THUNDERSTORM CAN NOT BE RULE OUT IN SE WV AS THE FRONT ENTERS THE
AREA. VERY STRONG WEST THEN NORTHWEST FLOW WILL DEVELOP BEHIND THE
FRONT BETWEEN ROUGHLY 09 AND 15Z. THE HIGHER RIDGE TOPS MAY SEE
GUSTS IN THE 40 TO 45 KTS RANGE...WITH GUSTS OF 20 TO 30 KTS
COMMON AT LOWER ELEVATIONS IN THE MOUNTAINS. THESE STRONG WINDS
WILL ALLOW FOR ENOUGH SUBSIDENCE TO PRECLUDE MOISTURE FROM MAKING
EAST OF THE MOUNTAINS. ANY SUB-VFR CONDTIONS IN THE MOUNTAINS WILL
IMPROVE QUICKLY AFTER ABOUT 12Z.

A MUCH STRONGER COLD FRONT WILL BRING REDUCED VISIBILITIES AND
LOWER CEILINGS WEDNESDAY AND WEDNESDAY NIGHT.
