AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
1016 AM EDT SAT SEP 3 2011
.SYNOPSIS...
WEAK HIGH PRESSURE WILL PERSIST OFF THE MID ATLANTIC COAST THROUGH
TONIGHT. A COLD FRONT WILL APPROACH LATE SUNDAY AND MOVE ACROSS
THE REGION ON MONDAY...BEFORE STALLING TO THE SOUTHEAST. MOISTURE
WILL RIDE ALONG THIS BOUNDARY THROUGH MUCH OF NEXT WEEK...BRINGING
THE POTENTIAL FOR SIGNIFICANT RAINFALL TO THE MID- ATLANTIC.
&&
.NEAR TERM /THROUGH TONIGHT/...
MADE A FEW TWEAKS TO THE ONGOING FORECAST. MAINLY FOR POPS. ELEVATED
THUNDERSTORMS HAVE DEVELOPED ACROSS THE NORTHEAST PORTION OF THE
FORECAST AREA THIS MORNING. THESE STORMS ARE MOVING SLIGHTLY WEST OF
SOUTH AT THIS TIME. THE MAIN CONCERNS WITH THESE THUNDERSTORMS WILL
BE HAIL...HEAVY RAINFALL...AND PROLIFIC LIGHTNING.
&&
.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
DEEP LYR SWLY FLOW ESTABLISHES ACRS MID-ATLC SUN...AS UPR TROF DIGS
INTO GREAT LAKES. THIS FLOW WILL ADVECT HEAT AND HUMIDITY UP THE ERN
SEABOARD. MAXIMA SHUD REACH 90F MANY AREAS...WITH HEAT INDICES INTO
U90S. TERRAIN WILL ACT AS LIFT ENHANCER...THUS WITH AMPLE MOISTURE
AND INSTABILITY...SHWRS/TSTMS LIKELY ACRS POTOMAC HIGHLANDS WITH
HIGH CHC POPS ALONG/WEST OF BLUE RIDGE...POSSIBLY AIDED BY SUBTLE
LEE TROFG. TSTM CHCS CONT THRU SUN NGT AS CDFNT APPROACHES FROM OH
VLY. LIKE DURG DAYTIME...BEST CHCS WRN ZONES WITH LOW CHC POPS ACRS
URBAN CORRIDOR.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
CONFIDENCE IS INCREASING IN XTDD PD HVY RN EVENT. CDFNT WILL DRAG
SLOWLY SEWD ACRS CWA MON/MON NGT...ORIENTED NEARLY PARALLEL TO
M/ULVL FLOW. RICH PLUME OF MOISTURE IN ASSOCIATION WITH TS LEE WILL
FUNNEL NEWD FROM GULF ALONG CDFNT INTO MID-ATLC. PWATS IN EXCESS OF
2 IN XPCD. POPS RAISED TO CATEGORICAL WRN ZONES MON...WITH HIGH
CHC/LIKELY POPS CONTG THRU WED MOST AREAS. STILL REASONABLE
UNCERTAINTY IN DETAILS OF LOCATION/TIMING OF SFC BNDRY AND
TS/REMNANTS OF LEE...BUT GENERAL SCENARIO LOOKS TO HOLD NEARLY
STATIONARY FRONT OVR OR JUST S/E OF CWA THRU MUCH OF THE WEEK...WITH
TROPICAL LOW PRESSURE RMNG SW/W OF RGN THRU ENTIRE PD. LLVL EASTERLY
FLOW COMBINED WITH ANOMALOUSLY MOIST M/ULVLS ORIGINATING FROM GULF OF
MEXICO COULD LEAD TO SIGNIFICANT PRECIPITATION...AND LATEST HPC
5-DAY PRECIP TOTALS EXCESS 3 INCHES ACRS MUCH OF CWA. WITH
ANTECEDENT CONDS WET FROM IRENE AND PREV RNS...THREAT FOR
FLOOD/FLASH FLOODING EXISTS BEGINNING MON AND CONTINUING WELL INTO
NEXT WEEK. CURRENT FCST IS HIGHLY DEPENDENT ON TRACK OF LEE...AND
SIGNIFICANT CHANGES ARE LIKELY IF PATH DEVIATES FROM PRESENT
PROJECTIONS.
&&
.AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...
CLUSTER OF ELEVATED THUNDERSTORMS HAVE DEVELOPED WEST OF THE METRO
AREAS THIS MORNING. CIGS/VSBYS WILL BE IMPACTED AT KIAD FOR THE
NEXT HOUR IN HEAVY RAIN. LIGHT SLY FLOW BECOMES SWLY TONIGHT AS
TROUGH APPROACHES.
SUN MRNG MVFR CIGS PSBL...WITH SHWRS/TSTMS DVLPG BY AFTN AS CDFNT
APPROACHES FROM NW. FRONT WILL DRAG THRU MID ATLC THRU AT LEAST
MON...LIKELY BRINGING SHWRS AND SUB-VFR VSBY/CIGS. SYSTEM MAY STALL
JUST S OF AREA WITH MOISTURE IN ASSOCIATION WITH NOW TROPICAL STORM
LEE MOVING ALONG AND NORTH OF THE BOUNDARY. THIS COULD CREATE A
PROLONGED AND SIGNIFICANT WET PERIOD ALONG WITH VSBY/CIG
RESTRICTIONS WELL INTO NEXT WEEK.
&&
.MARINE...
SLY FLOW 10 TO 15 KT THROUGH THE AFTERNOON. EVENING CHANNELING WILL
BRING MARGINAL GUSTS TO AROUND 20 KT. LEFT SMALL CRAFT ADVISORY AS
IS...SOUTH OF SANDY POINT BEGINNING AT 8PM AND CONTINUING THROUGH
THE NIGHT.
PRES GRADIENT BTWN N ATLC HIPRES AND APPROACHING CDFNT FROM OH VLY
WILL LEAD TO 10-15KT SLY WINDS SUN/SUN NGT. THOUGH GUSTS TO 20 KT
ARE POSSIBLE SUN...CONFIDENCE NOT QUITE HIGH ENUF FOR HEADLINES
ATTM...AS DIURNAL INVERSION CUD KEEP SPEEDS DOWN A BIT. CHANNELING SUN
NGT CREATES MORE LIKELY SCA CONDS. SHWRS/TSTMS LIKELY BY MON AFTN AS
SLOW MOVG FRONT APPROACHES WATERS...AND PRECIP CHCS WILL CONT THRU
MUCH OF NEXT WEEK AS MOISTURE FROM NOW TS LEE FLOWS NEWD THRU
MID-ATLC.
&&
.TIDES/COASTAL FLOODING...
SLY FLOW 10 TO 15 KT THROUGH THIS AFTERNOON...THEN 15 TO 20 KT
THIS EVENING /HIGHER THAN FRIDAY/. SLOWLY RISING TIDAL DEPARTURES
ARE EXPECTED THROUGH TONIGHT. THE LESS PREFERRED HIGH TIDE LATE
THIS MORNING/EARLY AFTERNOON WILL BE CLOSE BUT EXPECTED BELOW
FLOODING CRITERIA. HOWEVER...MINOR COASTAL FLOODING IS EXPECTED
AGAIN FOR THE EVENING/EARLY OVERNIGHT HIGH TIDE. EXPECT TIDAL
DEPARTURES OF 1.0 TO 1.5 FT ABOVE ASTRONOMICAL TONIGHT...SO THE
COASTAL FLOODING TONIGHT LOOKS A BIT MORE SIGNIFICANT /THOUGH
STILL MINOR/ THAN FRIDAY NIGHT.
SLY FLOW MAY PERSIST INTO SUN NGT IN ADVANCE OF SLOW MOVG CDFNT.
EVEN IF WINDS SUBSIDE...LOW PRESSURE AND FAVORABLE LUNAR CYCLE CUD
STILL LEAD TO MINOR COASTAL FLOODING NEAR ERY MRNG HIGH TIDES.
