AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
437 PM EDT FRI JUL 16 2010
.SYNOPSIS...
HIGH PRESSURE REMAINS CENTERED WELL OFF THE SOUTHEAST COAST
THROUGH THE WEEKEND. A COLD FRONT WILL GRADUALLY APPROACH THE MID
ATLANTIC REGION FROM THE NORTHWEST ON SATURDAY...THEN CROSS THE
REGION SATURDAY NIGHT BEFORE STALLING OVER THE CAROLINAS SUNDAY
AND MONDAY. ANOTHER WEAK FRONT DROPS INTO THE MID ATLANTIC REGION
ON TUESDAY...THEN LIFTS NORTH AS A WARM FRONT ON WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
ISOLATED-SCATTERED TSTMS ARE BECOMING MORE ORGANIZED OVER SRN VA W
OF CHES BAY...SUPPORTED BY MUCAPES BTWN 2500-3500 J/KG AND (MORE
IMPORTANTLY) SOME LIFT SUPPORT ALONG A SHARPENING LEE-SIDE TROUGH.
MORE NUMEROUS...LINEAR CONVECTION IS NOTED OVER WEST-CENTRAL VA
AND WRN NC...IN LIGHT OF THE ENHANCED LOW-MID LVL FGEN (QVECTOR
CONVERGENCE) PER THE MID LEVEL SHEAR AXIS TRAVERSING THE LWR OH
VLY. THIS SHEAR AXIS IS NOTED FAIRLY NICELY VIA THE INFLECTION
POINT ON THE LATEST STLT WV LOOPS.
TONIGHT...WILL MAINTAIN THE HIGHER POPS OVER INLAND AREAS NW OF
THE LOWER TIDEWATER REGION...GIVEN THE EARLIER TIMING AND
(THEREFORE) GREATER LLVL INSTBY TO WORK WITH. ELSEWHERE...HAVE
CONTINUED WITH THE ISOLD/SLIGHT CHANCE POPS. A WARM MUGGY NGT
LOOKS TO PREVAIL...SW FLOW WILL KEEP LOWS IN THE 70S ALL AREAS
(EVEN A FEW UPR 70S IN URBAN AREAS ACROSS SERN PTNS...SEE CLIMATE
SECTION BLO.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
A LITTLE BETTER CHANCES FOR SHWRS/TSTMS ARRIVES SAT W/ APPRCHG
COLD FRONT...STILL A LOT OF UNCERTAINTY HOWEVER AS TO PRECIP
COVERAGE AND POTENTIAL FOR PRECIP TO DIMINISH E OF THE
APPALACHIANS GIVEN A CONTINUED SW TO WSW LOW LVL FLOW (WHICH MAY
LEAD TO DOWNSLOPING EFFECTS). NAM/GFS/SREF/ECMWF WERE A LITTLE
BETTER ALIGNED WITH THE 12Z RUNS AS THE SFC FRONT DRAWS CLOSER.
TAKING A BLEND OF MODEL POPS...HIGHEST CHANCES (AGAIN) APPEAR TO
BE OVER SW AND CENTRAL PTNS OF THE FCST AREA...WTIH PROBS
DECREASING TO SLIGHT CHANCE/ISOLD AT BEST OVER THE LWR ERN SHORE.
AGAIN...SW/WSW LLVL FLOW WILL COMPLICATE MATTERS...AS THE DOWNSLOPE
COMPONENT E OF THE MNTNS WOULD AGAIN TEND TO DRY THE LOWER LAYERS
AT LEAST A LITTLE BIT.
HIGHS INTO THE LWR-MID 90S OVER MOST OF THE REGION...THOUGH WITH
HEAT INDICES SLIGHTLY LOWER THAN TODAY (STILL ARND 100). ON
SUNDAY...AS FRONT STALLS OVER NC...MORE LIMITED CHCS OF PRECIP
OVER THE NORTH...BUT WILL CONTINUE W/ 30-40% POPS FARTHER S. HIGHS
MAINLY IN THE LWR 90S SUN.
ANOTHER SEASONABLY HOT DAY AGAIN ON MON AS THE FCST REGION IS IN
BTWN THE STALLED (WASHED OUT) FRONT TO THE S...AND THE NEXT WEAK
FRONT APPROACHING FROM THE N. LLVL THICKNESS GUIDANCE SUPPORTS
HIGHS IN THE LWR-MID 90S...AS CONVECTIVE TEMPS RISE INTO THE MID
90S.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
EXTENDED PERIOD LOOKS TO BE DOMINATED BY UPR RIDGE GRADUALLY
BUILDING INTO THE MID-ATL REGION FOR THE MID TO LATE WEEK
PERIOD...WITH SFC RIDGE REMAINING ANCHORED OVER BERMUDA/WESTERN
ATLANTIC. THIS SHOULD TRANSLATE TO CONTINUES VERY WARM AND
REASONABLY HUMID WX. NO EVIDENT NON-DIURNAL FOCUS FOR CONVECTION SO
WL CONTINUE TO LEAN TWDS CLIMATOLOGICALLY TYPICAL ISO/WIDELY SCT
DIURNALLY-DRIVEN PCPN CHCS W/SILENT POP/PARTLY TO MOSTLY CLR SKY
DURING THE OVERNIGHT/ERY MORNING HOURS.
BY LATE IN THE WEEK...~STRONG 596-598 DCM UPR RIDGE FORECAST TO
TRANSLATE EASTWARD...WHICH WL LKLY TURN THE HEAT UP IN EARNEST
(AGAIN) FOR NEXT WEEKEND. HV GONE W/HIGHS GENERALLY IN THE LOW TO
MID 90S FOR THE PERIOD W/ERY MORNING LOWS RANGING FROM U60S FAR NW
TO L/M 70S ELSEWHERE...ABT A CATEGORY OR SO ABV CLIMO VALUES. BY
THU/FRI...HV CONTINUED TREND FORECAST MAXIMA UPWARDS A DEGREE OR SO
INTO THE M/U90S FOR MOST ZONES (SLIGHTLY COOLER FOR IMMEDIATE
COASTAL ZNS) BY NEXT FRIDAY.
&&
.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
CURRENTLY VFR CONDITIONS AT ALL TAF SITES. BR AND LOW CEILINGS WERE
TOUGH TO BURN OFF THIS MORNING BUT HAVE NOW TRANSITIONED INTO A CU
FIELD AT 3.5-6K FT AREA WIDE. WINDS ARE CURRENTLY 10-12 KTS AND
GUSTING AS HIGH AS 18 KTS IN SOME AREAS. SHOWERS AND THUNDERSTORMS
ARE POPPING UP AND WILL CONTINUE INTO THE EVENING HOURS.
A COLD FRONT APPROACHES ON SATURDAY BRINGING A BETTER CHANCE OF
STORMS. THE FRONT THEN STALLS OVER THE AREA SUNDAY CONTINUING THE
CHANCE FOR DEVELOPMENT. HIGH PRESSURE MOVES BACK INTO THE AREA ON
MONDAY.
&&
.MARINE...
BENIGN WX AND GOOD BOATING CONDITIONS ARE ON THE WAY FOR THE WEEKEND
INTO ERY NEXT WEEK W/TYPICAL DIURNAL SEABREEZE PROCESSES DOMINATING
FOR THE WEEKEND THRU ERY-MID NEXT WEEK. WNDS OVER THE NORTHERN BAY
ZNS ARE MARGINAL ATTM (13-15KT...GUSTS TO ~20KT). RUC HAS HANDLED
THESE WNDS WELL TODAY...SO WL FOLLOW ITS LEAD AND HOIST A QUICK SCA
THROUGH EARLY THIS EVENING IN ANTICIPATION OF A SMALL WINDOW OF NEAR
SCA CONDITIONS. THEREAFTER...STILL APPEARS THAT WEAK GRADIENT/SURGE
ASSOCIATED WITH THE WEAKENING FRONT SHOULD ALLOW WNDS TO DIMINISH
BELOW SCA OVERNIGHT. FOR THAT REASON...WL RUN SCA FOR THE BAY
THROUGH MIDNIGHT TONIGHT FOR NOW...AND ALLOW EVENING CREW TO
RE-ASSESS THIS EVENING REGARDING POTENTIALLY EXTENDING FARTHER INTO
ERY SATURDAY MORNING. HV ALSO BUMPED UP SWELL FOR THE OVERNIGHT
HOURS TONIGHT AS PER THE LATEST SWAN...WHICH BUILDS NORTHERN/CENTRAL
COASTAL ZNS TO NEAR SCA CRITERIA ON BUILDING SHORT PERIOD SE SWELL.
WILL CONTINUE TO CAP SEAS BELOW SCA CRIT AT ~4FT...WITH 5-6 FOOTERS
LOOKING TO HOLD WELL OFFSHORE. EITHER WAY...WNDS/WAVES LOOK TO
DIMINISH FOR LTR TOMORROW INTO NEXT WEEK AS HIGH PRESSURE BUILDS
INTO THE REGION THROUGH THE FIRST HALF OF NEXT WEEK. PCPN CHCS
SHOULD REMAIN LIMITED TO TYPICAL DIURNALLY-DRIVEN CONVECTION.
