AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
440 AM EDT FRI JUL 25 2008
.SYNOPSIS...
WEAK HIGH PRESSURE WILL BUILD IN TO THE REGION TODAY...ALLOWING FOR
SEASONABLE TEMPERATURES AND DRY CONDITIONS THROUGH AT LEAST THE FIRST
HALF OF THE WEEKEND. A WEAK AREA OF LOW PRESSURE WILL MOVE INTO
THE MID ATLANTIC REGION ON SUNDAY AND MONDAY...AHEAD OF A COLD FRONT
THAT WILL PUSH THROUGH THE AREA MONDAY NIGHT AND EARLY TUESDAY.
HIGH PRESSURE RETURNS ACROSS THE MID ATLANTIC REGION ON WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
RELATIVELY BENIGN FCST ACROSS THE REGION TODAY...AS WEAK HIGH
PRESSURE REMAINS INTACT OVER THE AREA. LLVL NE-E ONSHORE FLOW IS
MAINTAINING QUITE A BIT OF BNDRY LAYER MSTR ACROSS THE ERN PTNS OF
THE FCST AREA...EVIDENCED BY THE INCREASED SFC DWPTS AND AREAS OF
FOG.
LATER TODAY...HIGH PRESSURE/SUBSIDENCE IN PLAY ALONG WITH THE
CONTINUED ONSHORE FLOW WILL ALLOW FOR MOSTLY SUNNY CONDITIONS AND
SEASONABLE TEMPS. FCST MODEL SOUNDINGS DO INDICATE DIURNAL CU
DEVELOPMENT TODAY...PARTICULARLY ACROSS INLAND E/SE PTNS OF THE
AREA GIVEN THE HIGHER DEWPOINTS. THERMODYNAMICS ARE RATHER
WEAK/SHALLOW HOWEVER...GIVEN THE RATHER STRONG SUBSIDENCE
INVERSION BTWN 850-750 MB AND RELATIVE WARMTH FARTHER ALOFT. SO
AT MOST EXPECT SEABREEZE CONVERGENT BNDRYS TO PRODUCE MORE
ORGANIZED AREAS OF CU TODAY (SCT TO AT TIMES BKN COVERAGE)...
THOUGH PRIMARILY THE LLVL/FLAT VARIETY.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/...
GFS AND NAM ARE AGAIN SHOWING VARYING SOLUTIONS ACROSS THE FCST
AREA OVER THE WEEKEND. DIFFERENCES MAY APPEAR SUBTLE...BUT WOULD
HAVE A SIGNIFICANT IMPACT ON THE FCST FOR THE MID ATLC REGION.
BOTH MODELS SHOW WEAK MID/UPPER LVL TROUGHING ACROSS THE AREA THIS
WEEKEND...HOWEVER THE NAM INDICATES MORE OF A SFC REFLECTION
(BROAD AREA OF LLVL MOISTURE/THETA-E CONVERGENCE) ACROSS THE SERN
STATES AND EXPANDING NE TO THE MID ATLC REGION SAT NIGHT AND SUN.
THE GFS MEANWHILE SHOWS WEAK SFC HIGH PRESSURE REMAINING IN
PLACE...WITH LLVL MOIST AXIS/THETA-E RIDGE REMAINING TO OUR S. IT
SHOULD BE NOTED THAT THE 00Z NAM HAS TRENDED TOWARD A WETTER
SCENARIO COMPARED TO ITS 12Z THU PREDECESSOR...MEANWHILE THE
LATEST SREFS SUPPORT THE DRIER GFS SOLUTION. AS A RESULT...HAVE
SCALED BACK ON POPS ACROSS THE FCST AREA THIS WEEKEND...
PARTICULARLY ON SAT.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
BASIC AGREEMENT AMONG MODELS KEEPING THE TROUGH OVER THE EAST COAST
FOR MOST OF THE UPCOMING WORK WEEK. DISAGREEMENT COMES IN TIMING
ANY HIGHER/LOWER CHANCES OF RAIN THROUGHOUT THE WEEK...OUTSIDE OF
THE ENHANCED CHANCES ALONG/AHEAD OF THE NEXT WEAK COLD FRONT MON
AFTN-MON NIGHT. FROM TUE ON...RATHER THAN GO WITH ANY MODEL IN
PARTICULAR (THE GFS AND ECMWF DEPICT OPPOSITE SCENARIOS THROUGHOUT
THE WEEK) HAVE STUCK WITH 20-30% POPS THROUGHOUT THE EXTENDED...
HIGHER CHANCES DURING DIURNALLY- FAVORED TIME PERIODS. ALL IN
ALL...LOOKS TO BE A RATHER UNSETTLED TIME PERIOD. AS FAR AS TEMPS
GO...WENT CLOSE TO CLIMO AVERAGES RIGHT NOW (WHICH IS SEVERAL
DEGREES ABOVE AND BELOW MEX GUIDANCE DEPENDING ON THE DAY) DUE TO
UNCERTAINTY.
&&
.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
PATCHY FOG DVLPG OVR THE RGN...ESP OVER AREAS THAT SAW THE HEAVIEST
RAINFALL OVER THE PAST FEW DAYS. MOST AREAS ONLY SEEING MVFR VSBYS
TWRDS SUNRISE (ESP ALONG AND EAST OF 1-94). SOME VSBYS AND SHALLOW
LOW CLDS COULD FALL TO IFR/LIFR FOR A TIME TWRDS 12Z AND LOOK TO
ERODE QUICKLY TO VFR.
SOME IFR/LIFR RESTRICTIONS TO SHALLOW FOG ONCE AGAIN (ESP SBY) LATE
TNT BEFORE VFR PREVAILS ON SAT BEFORE UNSETTLED CONDITIONS RETURN
BEGINNING SUN.
&&
.MARINE...
VARIABLE WINDS EARLY THIS MORNING WITH EASTERLY COMPONENT TO THE
WINDS TODAY. GENERALLY LOOKING AT AOB 10 KTS. SPEEDS INCREASE
SLIGHTLY ON SUNDAY AS A FRONTAL BOUNDARY APPROACHES BUT WINDS AT H92
ONLY AROUND 20 KTS WHICH SHOULD KEEP SPEEDS AT THE SFC BLO SCA
CRITERIA. THE BOUNDARY REMAINS OVER THE AREA FOR THE FIRST PART OF
THE WORK WEEK SO HAVE KEPT WINDS SW FOR NOW...BUT THIS COULD CHANGE
BASED ON EXACT LOCATION OF BOUNDARY.
