Heavy Rain in Virginia, August 11, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
224 PM EDT SAT AUG 11 2012

.SYNOPSIS...
A COLD FRONT WILL STALL ACROSS CENTRAL VIRGINIA THIS AFTERNOON
INTO SUNDAY. SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS WILL
OCCUR TODAY WITH SCATTERED SHOWERS AND THUNDERSTORMS AGAIN ON
SUNDAY. HIGH PRESSURE WILL THEN BUILD OVER THE AREA SUNDAY THROUGH
EARLY NEXT WEEK. DAYTIME TEMPERATURES WILL BE SLIGHTLY BELOW
NORMAL TODAY BEFORE A SLIGHT WARMING TREND THROUGH EARLY NEXT
WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
OCCLUDED LOW CURRENTLY LOCATED EASTERN MICHIGAN WITH A COLD FRONT
SLOWLY APPROACHING WESTERN PORTIONS OF THE FA. THE FRONT WILL
SLOWLY PUSH EAST BEFORE STALLING NEAR INTERSTATE 95 THIS
AFTERNOON. MOISTURE WILL NOT BE A PROBLEM AGAIN TODAY WITH PRECIP
WATERS AOA 2 INCHES. HOWEVER...UNLIKE YESTERDAY...WHICH LACKED A
GOOD TRIGGER... A MID LEVEL VORT LOBE ROUNDING THE BASE OF THE
TROUGH (PRESENTLY OVER THE WESTERN CAROLINAS) WILL HELP ENHANCE
SHOWERS/THUNDERSTORMS ALONG THE FRONT THIS MORNING. ALSO THIS
MORNING...PVA IN SWLY FLOW ALONG THE COAST WILL HELP KEEP
SCATTERED SHOWERS/THUNDERSTORMS IN THE FORECAST WELL IN ADVANCE OF
THE FRONT. AS THE FRONT LOCATES ACROSS CENTRAL VA THIS
AFTERNOON...VORT MAX/SHORTWAVE AND STRONG DIVERGENCE ALOFT DUE TO
RRQ OF UPPER LEVEL JET WILL RESULT IN CONTINUED
SHOWERS/THUNDERSTORMS. WITH BEST MOISTURE ACROSS SE VA/NE NC...THE
BEST COVERAGE OF STORMS WILL BE EAST OF INTERSTATE 95.
HOWEVER...ADEQUATE MOISTURE AND AFOREMENTIONED FRONTAL LOCATION
WILL BE ENOUGH TO KEEP SCATTERED SHOWERS/THUNDERSTORMS ACROSS THE
ENTIRE REGION THIS AFTERNOON. AS FAR AS SEVERE WEATHER IS
CONCERNED...ABUNDANT CLOUD COVER AND RESULTANT LACK OF DAYTIME
HEATING WILL HELP LIMIT ANY AFTERNOON INSTABILITY. HOWEVER...MID
LEVEL FLOW 40 TO 50 KTS WILL RESULT IN AT LEAST AN ISOLATED
POSSIBILITY OF STRONG GUSTY WINDS AND HAIL. THE MAIN THREAT WILL BE
HEAVY RAINFALL WHICH COULD RESULT IN LOCALIZED FLOODING.

CLOUD COVER WILL RESULT IN DAYTIME TEMPERATURES IN THE MID 80S
AREA WIDE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
FRONTAL BOUNDARY WILL STALL ACROSS THE AREA WITH SECONDARY SFC LOW
DEVELOPING ACROSS DELMARVA SATURDAY NIGHT/SUNDAY MORNING. WHILE
SHOWER/THUNDERSTORM ACTIVITY WILL DECREASE TONIGHT...SUBTLE ENERGY
IN SWLY FLOW WILL BE ENOUGH TO KEEP ISOLATED/SCATTERED POPS IN THE
FORECAST OVERNIGHT...ESPECIALLY NEAR THE COAST. FOR SUNDAY...MID
LEVEL SHORTWAVE/VORT MAX WILL PROPAGATE ACROSS THE TN VALLEY INTO
CENTRAL VA SUNDAY AFTERNOON. THIS FEATURE COMBINED WITH SFC
FRONT/ABUNDANT MOISTURE FOR MORE SCATTERED SHOWERS/THUNDERSTORMS.
SEVERE WEATHER WILL BE LIMITED AGAIN SUNDAY AS ABUNDANT CLOUD COVER
WILL LIMIT DAYTIME HEATING. AS THE TROUGH AXIS PUSHES EAST OF THE
AREA SUNDAY EVENING...DRY DOWNSLOPING WINDS AND SFC HIGH PRESSURE
WILL HELP BRING AN END TO SHOWERS/THUNDERSTORMS. CLEARING SKIES
SUNDAY NIGHT WILL HELP TEMPERATURES COOL NICELY. MODEL SOUNDINGS ARE
CURRENTLY TOO DRY FOR FOG DEVELOPMENT BUT MAY NOT BE PICKING UP ON
AVAILABLE LOW LVL MOISTURE AT THIS POINT. HIGH PRESSURE MOVES
OVERHEAD THEN SHIFTS OFF THE COAST BY MONDAY EVENING. EXPECT A DRY
AND PLEASANT DAY UNDER MOSTLY-PARTLY SUNNY SKIES AS CUMULUS DEVELOPS
DURING THE AFTERNOON. A FEW SEABREEZE-INFLUENCED SHOWERS/STORMS MAY
BE POSSIBLE CLOSE TO THE COAST.

TEMPERATURES WILL WARM SLIGHTLY SUNDAY/MONDAY WITH DAYTIME
TEMPERATURES IN THE MID/UPPER 80S. CLEARING SKIES SUNDAY
NIGHT/MONDAY MORNING WILL ALLOW TEMPERATURES TO DROP INTO THE
MID/UPPER 60S INLAND AND UPPER 60S/LOW 70S NEAR THE COASTS.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
GENERALLY QUIET IS WX ON TAP FOR MUCH OF THE LONG TERM PERIOD. NO
MAJOR SYSTEMS EXPECTED TO IMPACT THE LOCAL AREA. NORMAL SUMMER WX IS
FORECAST.

GENERAL AREA OF LOW PRESSURE WILL PREVAIL OVER MUCH OF CANADA WITH
UPPER LEVEL RIDGING FROM THE SOUTHWEST STATES TO THE GULF OF MEXICO.
W/NW FLOW WILL COVER THE NORTHEAST AND MID ATLANTIC STATES.

WEAK SHORT WAVES AND DISSIPATING FRONTAL SYSTEMS MAY PRODUCE TSTMS
ACROSS THE AREA. SLIGHT TO LOW CHANCE POPS ARE FORECAST EACH DAY
EXCEPT THURSDAY...MAINLY IN THE FORM OF AFTERNOON AND EARLY EVENING
TSTMS. CONFIDENCE IN THE TIMING OF THESE SYSTEMS IS RATHER LOW AT
THIS TIME.

LITTLE DAY TO DAY CHANGE IS INDICATED. HIGH TEMPERATURES WILL BE IN
THE UPR 80S TO LWR 90S EXCEPT SLIGHTLY LOWER READINGS NEAR THE
COAST. LOW TEMPERATURES WILL RANGE FROM THE MID TO UPR 60S INLAND TO
THE LWR TO MID 70S AT THE COAST.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
SW FLOW CONTINUES ACROSS AREA. WINDS ARE EXPECTED TO BECOME GUSTY
15-20 KT THRU THE AFTN. LOTS OF MOISTURE CONVERGING FROM THE GULF
AND THE ATL OVER THE CAROLINAS AND MOVG QUICKLY TO THE N. BANDS OF
SHOWERS AND TSTMS ARE STREAMING NORTH AND AFFECTING MOSTLY SE VA
BUT WILL SPREAD OVER CENTRL VA AND NORTH DURING THE AFTN/EVENING.
GENERALLY EXPECT ALL THE TERMINALS TO EVENTUALLY BE AFFECTED BY
CONVECTION AS THE AIRMASS IS VERY MOIST AND UNSTABLE. A FRONT
EXTENDS THRU THE PIEDMONT AND IS MOSTLY STNRY.

COLD FRONT TO THE WEST WILL MOVE VERY LITTLE TODAY AND LIKELY PUSH
PAST RIC DURING THE OVERNIGHT.

SLOW CLEARING LATE SAT NIGHT INTO SUNDAY WITH FRONT SLOWLY
CROSSING IN FROM THE WEST. WILL LKLY SEE SOME MVFR/IFR EARLY WITH
CLEARING SUNDAY MORNING INLAND. GRADUAL IMPROVEMENT SUNDAY WITH
MAINLY VFR CONDS SUNDAY NIGHT-TUESDAY.

&&

.MARINE...
LATEST OBS REFLECT PRESSURE GRADIENT BETWEEN THE WESTERN
FRINGES OF BERMUDA HIGH TO OUR SOUTHEAST AND STRONG LOW PRESSURE
OVER THE GREAT LAKES REGION...WHICH CONTINUES TO PRODUCE SCA WINDS
OVER THE WATERS THIS MORNING. SLOW MOVING SFC COLD FRONT REMAINS
ORIENTED WEST OF THE REGION THIS MORNING...AND WILL REMAIN WEST OF
THE WATERS THROUGH TONIGHT. PRESSURE GRADIENT SLOWLY SLACKENS
TONIGHT, WITH WINDS GRADUALLY DIMINISHING INTO SUNDAY MORNING AS
WINDS VEER TO THE WEST AHEAD OF WEAKENING FRONT APPROACHING FROM THE
WEST. SCA REMAINS IN EFFECT THROUGH MIDDAY OVER ALL ZONES...FOR THE
CHES BAY THROUGH LATE TONIGHT AND FOR ALL ATLANTIC COASTAL ZONES
THROUGH AROUND DAWN SUNDAY MORNING.

AN EXTENDED PERIOD OF QUIET WEATHER OVER THE MARINE AREA WILL RETURN
FOR SUNDAY THROUGH THE MIDDLE OF NEXT WEEK. WINDS DIMINISH QUICKLY
AS FRONT WASHES OUT WEST OF THE WATERS. WINDS BECOME LIGHT WITH SEAS
AVERAGING AOB 3 FT THROUGH MON NGT. NEXT FRONT APPROACHES FROM THE
WEST BY MIDWEEK, THOUGH CONDITIONS EXPECTED TO REMAIN SUB-SCA ATTM.
