AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
342 AM EST FRI FEB 24 2012

.SYNOPSIS...
A STRONG COLD FRONT WITH GUSTY WINDS WILL CROSS THE REGION TODAY
BEFORE HIGH PRESSURE BUILDS INTO THE AREA THIS WEEKEND. HIGH
PRESSURE WILL MOVE OFF THE COAST MONDAY AND A STORM SYSTEM MAY
IMPACT THE AREA DURING THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SURFACE LOW PRESSURE IS LOCATED OVER THE OHIO VALLEY THIS MORNING. A
WARM FRONT EXTENDS EAST FROM THIS BOUNDARY ACROSS NORTHERN VIRGINIA
INTO CENTRAL MARYLAND WHILE A COLD FRONT EXTENDS SOUTHWEST FROM THE
BOUNDARY THROUGH THE TENNESSEE VALLEY INTO THE DEEP SOUTH.
ISENTROPIC LIFT AHEAD OF THE WARM FRONT WILL CAUSE SHOWERS ALONG AND
NORTH OF THE WARM FRONT EARLY THIS MORNING. SHOWERS AND
THUNDERSTORMS AHEAD OF THE COLD FRONT OVER WEST VIRGINIA WILL MOVE
EAST INTO THE ALLEGHENY AND POTOMAC HIGHLANDS EARLY THIS MORNING.
HOWEVER...THUNDERSTORMS ARE EXPECTED TO WEAKEN SINCE THE AIRMASS IS
NOT AS UNSTABLE.

THE SURFACE LOW WILL INTENSIFY AS IT MOVES INTO THE EASTERN GREAT
LAKES LATER THIS MORNING AND AFTERNOON. THE WARM FRONT WILL LIFT
NORTH THROUGH NORTHERN MARYLAND DURING THIS TIME. SOUTHWEST WINDS
BEHIND THE WARM FRONT WILL COMBINE WITH SOME SUNSHINE TO USHER IN
VERY WARM CONDITIONS FOR THIS TIME OF YEAR. MAX TEMPS WILL RANGE
FROM THE LOWER TO MIDDLE 60S NEAR THE MASON-DIXON LINE...TO THE
MIDDLE 70S IN WASHINGTON DC...TO THE UPPER 70S ACROSS PORTIONS OF
CENTRAL VIRGINIA.

SOUTHWEST WINDS WILL ALSO USHER IN INCREASING AMOUNTS OF LOW-LEVEL
MOISTURE. DEWPOINTS IN THE 50S ARE EXPECTED BEHIND THE WARM FRONT.
THE COLD FRONT CURRENTLY LOCATED OVER THE OHIO VALLEY THIS MORNING
WILL MOVE EAST PASSING THROUGH OUR AREA THIS AFTERNOON. WARM AND
MOIST AIR WILL CAUSE INSTABILITY TO DEVELOP ALONG AND AHEAD OF THE
COLD FRONT. THE COMBINATION OF FORCING FROM THE COLD FRONT ALONG
WITH INSTABILITY WILL BRING THE CHANCE FOR SHOWERS/T-STORMS THIS
AFTERNOON.  STRONG WINDS ALOFT ALONG WITH AN INVERTED V SIGNATURE IN
THE FORECAST SOUNDINGS INDICATES THAT DAMAGING WINDS ARE POSSIBLE IN
ANY THUNDERSTORMS THAT DEVELOP. THE BEST CHANCE FOR THUNDERSTORMS TO
PRODUCE DAMAGING WINDS WILL BE ACROSS LOWER SOUTHERN MARYLAND INTO
THE VIRGINIA PIEDMONT WHERE THE MOST INSTABILITY IS EXPECTED. HAIL
IS ALSO POSSIBLE IN THE STRONGER THUNDERSTORMS THIS AFTERNOON.

A STRONG PRESSURE SURGE BEHIND THE COLD FRONT THIS AFTERNOON ALONG
WITH COLD ADVECTION WILL CAUSE STRONG WINDS FROM ALOFT TO MIX DOWN
TO THE SURFACE. A HIGH WIND WARNING IS IN EFFECT FOR NORTH-CENTRAL
MARYLAND AS WELL AS ALL LOCATIONS ALONG AND WEST OF THE BLUE RIDGE
MOUNTAINS. A WIND ADVISORY IS IN EFFECT BEGINNING AT 3PM THIS
AFTERNOON FOR WASHINGTON AND BALTIMORE AS WELL AS LOWER SOUTHERN
MARYLAND INTO THE VIRGINIA PIEDMONT. WIND GUSTS AROUND 60 MPH ARE
EXPECTED WITHIN THE HIGH WIND WARNING AND WIND GUSTS AROUND 50 TO 55
MPH ARE EXPECTED WITHIN THE WIND ADVISORY.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/...
THE COLD FRONT WILL CONTINUE TO MOVE EAST OF THE AREA TONIGHT. A
STRONG PRESSURE GRADIENT ALONG WITH COLD ADVECTION WILL CAUSE GUSTY
WINDS TONIGHT. A HIGH WIND WARNING REMAINS IN EFFECT FOR
NORTH-CENTRAL MARYLAND AS WELL AS LOCATIONS ALONG AND WEST OF THE
BLUE RIDGE MOUNTAINS. THE WIND ADVISORY REMAINS IN EFFECT UNTIL
MIDNIGHT FOR WASHINGTON AND BALTIMORE AS WELL AS LOWER SOUTHERN
MARYLAND AND THE VIRGINIA PIEDMONT. A WIND ADVISORY MAY BE NEEDED
FOR PORTIONS OF THE CWA LATE TONIGHT...ESPECIALLY ACROSS THE HIGHER
ELEVATIONS.

UPSLOPE SNOW SHOWERS ARE EXPECTED TO DEVELOP TONIGHT FOR LOCATIONS
ALONG AND WEST OF THE ALLEGHENY FRONT. A FEW INCHES OF SNOW ARE
POSSIBLE ALONG THE RIDGE TOPS. A WINTER WEATHER ADVISORY MAY BE
WARRANTED FOR THESE AREAS.

NOTICEABLY CHILLIER CONDITIONS ARE EXPECTED TONIGHT WITH MIN TEMPS
RANGING FROM THE 20S IN THE ALLEGHENY HIGHLANDS TO NEAR 40 IN
WASHINGTON AND BALTIMORE. THE GUSTY WINDS WILL MAKE IT FEEL COLDER.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
UPPER LEVEL TROUGH PIVOTS THROUGH THE MID-ATLANTIC ON SATURDAY.
STRONG SURFACE LOW REACHES THE MARITIMES...WHILE HIGH PRESSURE MOVES
INTO THE OHIO VALLEY. PRESSURE GRADIENT BETWEEN THESE TWO SYSTEMS
WILL CONTINUE TO BE TIGHT...SO ANOTHER WINDY DAY IS EXPECTED.
ALTHOUGH GUSTS ARE NOT EXPECTED TO BE AS STRONG AS FRIDAY...NOT
COMPLETELY RULING OUT THE POSSIBILITY OF OCCASIONAL GUSTS
APPROACHING WIND ADVISORY CRITERIA IF MOMENTUM TRANSFER IS OPTIMAL.
THE STRONG NW FLOW WILL ALSO CONTRIBUTE TO ONGOING UPSLOPE SNOW OVER
THE POTOMAC HIGHLANDS. QPF IS SOMEWHAT LIMITED...BUT ANOTHER 1-2
INCHES WILL BE POSSIBLE SATURDAY MORNING THROUGH AFTERNOON.

MUCH COOLER TEMPS SATURDAY UNDER STRONG CAA. HIGHS RANGE FROM THE
LOW 30S OVER THE POTOMAC HIGHLANDS TO THE LOW 50S ALONG AND EAST OF
THE 95 CORRIDOR.

HIGH PRESSURE BUILDS TOWARDS THE EAST COAST SATURDAY NIGHT.
DECREASING WINDS AND SUBSIDENCE WILL SHUT OFF SNOW IN THE POTOMAC
HIGHLANDS...ALTHOUGH CHANCE POPS REMAIN UNTIL AFTER MIDNIGHT
SATURDAY NIGHT. WINDS GRADUALLY DECREASE IN THE EVENING AND SHOULD
BECOME LIGHT WITH DECOUPLING OVERNIGHT. LOWS RANGE FROM THE TEENS IN
THE POTOMAC HIGHLANDS TO AROUND 30 IN THE WASHINGTON AND BALTIMORE
METRO AREAS.

HIGH PRESSURE WILL BE OVERHEAD SUNDAY...RESULTING IN SUNSHINE AND
NEAR NORMAL TEMPERATURES.  DRY COLD FRONTAL PASSAGE EXPECTED MONDAY
AS A CLIPPER-TYPE LOW MOVES THROUGH SRN CANADA AND NEW
ENGLAND...WITH GUSTY WINDS POSSIBLE IN THE AFTERNOON. HIGH PRESSURE
RETURNS TUESDAY.  WET WEATHER POSSIBLE AGAIN WEDNESDAY WITH A COLD
FRONT APPROACHING FROM THE WEST. ABOVE-NORMAL TEMPS LIKELY EARLY
NEXT WEEK.

&&

.AVIATION /09Z FRIDAY THROUGH TUESDAY/...
A WARM FRONT WILL PASS THROUGH THE TERMINALS THIS MORNING. IFR
CIGS/VSBYS NORTH OF THE WARM FRONT EARLY THIS MORNING WILL IMPROVE
BEHIND THE WARM FRONT DURING THE MID TO LATE MORNING HOURS.
SOUTHWEST WINDS WILL INCREASE BEHIND THE WARM FRONT WITH GUSTS
AROUND 30 TO 35 KNOTS EXPECTED.

A COLD FRONT WILL PASS THROUGH THE TERMINALS THIS AFTERNOON.
SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE. THUNDERSTORMS MAY
CONTAIN GUSTY WINDS AND HAIL. STRONG WESTERLY WINDS ARE EXPECTED
BEHIND THE COLD FRONT LATE THIS AFTERNOON AND EVENING. WIND GUSTS
AROUND 45 TO 50 KNOTS ARE EXPECTED. WINDS WILL DIMINISH A LITTLE
AFTER MIDNIGHT....BUT WIND GUSTS AROUND 35 TO 40 KNOTS ARE STILL
POSSIBLE.

VFR CONDITIONS EXPECTED TO PREVAIL AT THE TERMINALS SATURDAY THROUGH
TUESDAY. GUSTY NW WINDS EXPECTED AGAIN SATURDAY...POTENTIALLY UP TO
30 KT OR HIGHER. WINDS DIMINISH SATURDAY NIGHT AND ARE EXPECTED TO
BE LESS THAN 10 KT THROUGH MONDAY MORNING. GUSTY WINDS POSSIBLE
AGAIN MON AFTN WITH A DRY COLD FRONTAL PASSAGE. NEXT CHANCE FOR

&&

.MARINE...

MORNING. EAST-SOUTHEAST WINDS WILL GUST UP TO 20 KNOTS. A WARM FRONT
WILL PASS THROUGH THE WATERS LATER THIS MORNING. SOUTHWEST WINDS
BEHIND THE WARM FRONT WILL INCREASE THIS AFTERNOON. WIND GUSTS
AROUND 25 TO 35 KNOTS ARE EXPECTED. A COLD FRONT WILL PASS THROUGH
THE WATERS LATE THIS AFTERNOON AND EVENING. WIND GUSTS AROUND 35 TO
45 KNOTS ARE EXPECTED BEHIND THE COLD FRONT LATE THIS AFTERNOON
THROUGH TONIGHT.

SCATTERED SHOWERS AND T-STORMS ARE POSSIBLE AHEAD OF THE COLD FRONT
THIS AFTERNOON. T-STORMS WILL BE CAPABLE OF PRODUCING DAMAGING WINDS
AND HAIL.

A GALE WARNING IS IN EFFECT FOR THE WATERS TODAY THROUGH TONIGHT
ALTHOUGH THE STRONGEST WINDS ARE EXPECTED LATE THIS AFTERNOON AND
TONIGHT.

STRONG SCA CONDITIONS EXPECTED AGAIN SATURDAY WITH
CONTINUED GUSTY NW WINDS BEHIND STRONG LOW PRESSURE ENTERING THE
MARITIMES. GALES WILL BE POSSIBLE...ALTHOUGH FORECAST LEANS TOWARDS
SUB-GALE GUSTS AT THIS TIME. WINDS DIMINISH SATURDAY NIGHT AS HIGH
PRESSURE BUILDS INTO THE MID-ATLANTIC. LIGHT WINDS EXPECTED SUNDAY.
SCA CONDITIONS POSSIBLE AGAIN MONDAY WITH A COLD FROPA.

&&

.FIRE WEATHER...
A COLD FRONT WILL PASS THROUGH THE AREA LATER THIS AFTERNOON INTO
TONIGHT. STRONG WINDS ARE EXPECTED BEHIND THE COLD FRONT WITH GUSTS
AROUND 50 TO 60 MPH EXPECTED. HOWEVER...FUEL MOISTURE IS A BIT
HIGHER DUE TO RAINFALL THAT OCCURRED OVERNIGHT. MORE SCATTERED
SHOWERS AND THUNDERSTORMS ARE EXPECTED AHEAD OF THE COLD FRONT
TODAY.

THE RELATIVE HUMIDITY WILL BE A BIT HIGHER BEHIND THE COLD FRONT
SINCE THE DRIEST AIR WILL HOLD OFF UNTIL TONIGHT WHEN COLDER
TEMPERATURES ARE EXPECTED. GIVEN THE HIGHER FUEL MOISTURE AND HIGHER
RELATIVE HUMIDITY...THE FIRE WEATHER WATCH HAS BEEN CANCELLED.
HOWEVER...STRONG WINDS ARE STILL EXPECTED THIS AFTERNOON THROUGH
TONIGHT.

GUSTY WINDS WILL CONTINUE SATURDAY BEHIND THE COLD FRONT AND DRY AIR
WILL CAUSE MUCH LOWER RELATIVE HUMIDITY VALUES COMPARED TO FRIDAY.
THEREFORE...AN ENHANCED THREAT FOR THE SPREAD OF WILDFIRES IS
POSSIBLE. WILL COORDINATE WITH STATE AGENCIES BY SATURDAY MORNING ON
FUEL MOISTURE TO DETERMINE THE POSSIBILITY OF A FIRE WEATHER
HEADLINE.
