AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
912 AM EST MON FEB 28 2011
.SYNOPSIS...
A COLD FRONT WILL CROSS THE REGION LATE THIS AFTERNOON AND WILL BE
ACCOMPANIED BY THUNDERSTORMS. HIGH PRESSURE BUILDS BRIEFLY INTO
THE MID-ATLANTIC REGION ON TUESDAY. A COLD FRONTAL PASSAGE IS
EXPECTED ON WEDNESDAY...BUT NO PRECIPITATION IS EXPECTED. HIGH
PRESSURE RETURNS FOR THE REMAINDER OF THE WEEK. A STORM SYSTEM
WILL IMPACT THE REGION OVER THE WEEKEND.
&&
.NEAR TERM /THROUGH TONIGHT/...
PRODUCTS UPDATED TO REFLECT TORNADO WATCH NUMBER 32.
6AM UPDATE...THE SYSTEM HAS PROGRESSED QUITE A BIT OVER
NIGHT...THE SFC LOW IS NOW OVER ERIE PA WITH THE FRONTAL LINES NOW
OVER EASTERN OH AND CNTRL KY. SEVERAL WIND GUSTS IN EXCESS OF 50
MPH HAVE BEEN MEASURED FROM THIS ACTIVITY.
EXPECTATION NOW IS FOR THE PREFRONTAL STORMS TO CROSS THE CWA
LATE THIS MORNING THROUGH THE EARLY AFTERNOON. A 45-55KT SWLY 925MB JET
PROVIDES STRONG MOISTURE AND HEAT TRANSPORT AHEAD OF THE COLD
FRONT. WITH SOME BREAKS IN THE MID-LEVEL CLOUD COVER...EXPECT MAX
TEMPS IN THE LOW 70S ACROSS N-CNTRL VA WITH AROUND 70F IN THE
BALTIMORE- WASHINGTON METRO.
PREVIOUS DISCUSSION...
A SLIGHT RISK FOR SEVERE WEATHER /DAMAGING WINDS/ HAS BEEN ISSUED
BY SPC. THE ORGANIZED LINES OF THUNDERSTORMS CURRENTLY AHEAD OF
THE COLD FRONT OVER THE MIDWEST ARE EXPECTED TO MOVE EAST ACROSS
THE CWA THIS AFTERNOON/EARLY EVENING. MODEST INSTABILITY WILL
ALLOW CONTINUED DEVELOPMENT OF THE ACTIVITY AS IT CROSSES THE
APPALACHIANS. CATEGORICAL HEAVY SHOWERS AND THUNDERSTORMS WITH
DAMAGING WIND WORDING ARE IN THE FORECAST FOR THIS AFTERNOON
ACROSS MOST OF THE CWA...THEN FOR THE EARLY EVENING FOR SOUTHERN
MARYLAND. GIVEN THE STRONG DYNAMICS OF THIS DEVELOPED
SYSTEM...THESE STORMS WILL BE FAST MOVING...SO AN ATTEMPT AT A
MORE PRECISE TIMING THAN THREE HOURS WAS NOT ATTEMPTED. QPF STILL
LOOKS TO BE ONE-HALF TO THREE- QUARTERS INCH. THIS WILL COME VERY
QUICKLY...THOUGH GENERALLY NOT ABOVE FLASH FLOOD THRESHOLDS.
TRAINING STORMS THAT BRING LONGER HEAVY RAIN TO DC OR BALTIMORE
WOULD CAUSE ISSUES IN THE FLASH FLOOD-PRONE URBAN AREAS.
THE COLD FRONT PUSHES EAST OF CWA THIS EVENING...WITH POST-
FRONTAL STRONG/GUSTY NWLY WINDS. DESPITE THIS BEING A NOCTURNAL
FROPA...STRONG COLD AIR ADVECTION IN THE PARTICULARLY DRY AIR
SPILLING IN SHOULD ALLOW GUSTS TO MIX DOWN TO THE SFC ACROSS THE
CWA. FCST SOUNDINGS CONTINUE TO SUGGEST A SURGE TO MARGINAL WIND
ADVISORY CRITERIA /GUSTS IN EXCESS OF 45 MPH/ IS POSSIBLE. THIS
POTENTIAL WILL BE REANALYZED WITH 06Z DATA LATER TONIGHT. GIVEN
DRY AIR MASS...LITTLE IF ANY UPSLOPE RAIN/SNOW IS EXPECTED WEST OF
THE ALLEGHENY FRONT POST FROPA. COLD AIR ADVECTION WILL CONTINUE
THROUGH THE NIGHT WITH CONSIDERABLE CLEARING. MIN TEMPS WILL BE IN
THE MID TO LOWER 20S OUT WEST. LOW 30S REACH EAST OF THE BLUE
RIDGE...WITH MID 30S URBAN/NEAR SHORE.
