Area forecast discussion, Jul 23, 3:45 PM EDT, 2 hours 42 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
345 PM EDT SAT JUL 23 2011
.SYNOPSIS...
THE CENTER OF THE UPPER RIDGE SLOWLY RETROGRADES THROUGH SUNDAY.
A COLD FRONT WILL SINK SOUTH TOWARD US EARLY NEXT WEEK. A BUBBLE
OF CANADIAN HIGH PRESSURE SCOOTS OVER THE MIDDLE ATLANTIC BY THE
MIDDLE OF THE WEEK...FOLLOWED BY ANOTHER WARM UP BY LATE WEEK.
&&
.NEAR TERM /THROUGH SUNDAY/...
VAPOR LOOP SHOWING THE RESIDUAL WEAK S/W NOW MOVING INTO THE AREA
WITH CLUSTERS OF SHRA/TSRA ONGOING AND HEADING SE IN THE NW FLOW
ALOFT. ALL MODELS WERE A BIT UNDERDONE ON CURRENT COVERAGE AND GIVEN
CAPES ABOVE 2500 J/KG IN MOST SPOTS EXPECT AT LEAST SCTD COVERAGE TO
CONTINUE INTO THE EVENING BEFORE LOSS OF HEATING CAUSES THINGS TO
DIMINISH. APPEARS BEST EVENING COVERAGE WILL OCCUR OVER THE NW WHERE
DEEPER FEED OF RH PREVAILS SO WILL RUN WITH HIGH CHANCE TO LOW
LIKELYS THERE AND BASICALLY DECENT CHANCES ELSW SINCE COVERAGE WILL
END UP DRIVEN BY OLD OUTFLOW. THESE WILL AGAIN TEND TO BE VERY SLOW
MOVERS WITH ADDED DOWNBURST POTENTIAL PER PWATS/DCAPES SO KEEPING
SEVERE MENTION IN THE HWO. TSRA SHOULD FINALLY FADE BY MIDNIGHT BUT
LEAVING IN SLIGHT CHANCE ACROSS THE NORTH/EAST WITH BETTER FOCUS TO
THE NORTH CLOSER TO THE UPSTREAM FRONT. OTRW HEAT ADVISORY CONTINUES
THRU 8 PM OVER THE EAST WHERE INDICES HAVE BEEN CLOSE TO 105 OUTSIDE
OF CONVECTION. SOME FOG ALSO LIKELY ESPCLY OVER THE WEST AND SE
WHERE EARLIER HEAVY RAINFALL HAS OCCURRED SO FAR. LOWS AGAIN ON THE
WARM AND MUGGY SIDE BUT MAY SEE TEMPS DROP A LITTLE MORE GIVEN
COOLING BY RAINFALL/OUTFLOW THRU EARLY EVENING.
UPPER HEIGHTS CONTINUE TO SLOWLY FALL ON SUNDAY WITH THE AXIS OF
PRE-FRONTAL MOISTURE SAGGING IN FROM THE NORTH DURING THE AFTERNOON.
THIS SHOULD AGAIN SET THE STAGE FOR ADDED CLUSTERS OF SHRA/TSRA WITH
UNIDIRECTIONAL WEST/NW FLOW ALOFT AND STRONG INSTABILITY OVER THE
NORTH AND WEST. STORMS SHOULD MOVE A BIT FASTER BUT GIVEN FCST
SOUNDINGS SHOWING A LITTLE MORE DRY AIR ALOFT EXPECT MORE MICROBURST
TYPE SEVERE THREAT. THUS WILL UP POPS TO DECENT CHANCE MOST AREAS
FOR NOW AND INCLUDE MENTION IN THE HWO. AGAIN THE OTHER CONCERN IS
WITH THE HEAT OVER THE PIEDMONT WHERE GUIDANCE IS PROGGING HIGHS AT
LEAST IN THE UPPER 90S...WHILE SHOWING A LITTLE MORE DRYING OF
DEWPOINTS IN A LITTLE BETTER WESTERLY FLOW. CURRENT INDICES SUPPORT
NOT ISSUING ANOTHER HEAT ADVISORY WITH ONLY AN HOUR OR TWO OF SEEING
VALUES JUST BELOW 105. THEREFORE WILL HOLD OFF ON EXTENDING THE NPW
INTO SUNDAY AND ALLOW THE MIDSHIFT ANOTHER LOOK SINCE DEWPOINTS HAVE
BEEN SLOWER TO FALL OFF TODAY THAN EXPECTED. OTRW WILL GO WITH A MOS
COMP WHICH PUTS MOST OF THE WEST IN THE 80S TO AROUND 90...AND
POINTS EAST IN THE 92-98 RANGE PENDING COVECTIVE COVERAGE.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
EXPECT TO SEE CONVECTION LINGERING ACROSS THE REGION INTO SUNDAY
EVENING AND COULD PERSIST LONGER AS MORE ORGANIZED COVERAGE CLOSER
TO THE FRONT ATTEMPTS TO DRIFT IN FROM THE NORTH. THUS SIMILAR TO
SAT...WILL KEEP HIGHEST POPS ACROSS THE NW WITH SLIGHT TO LOW
CHANCE SE FOR NOW. LOWS AGAIN QUITE MUGGY...MAINLY 68-75.
ON MONDAY...A COLD FRONT IS EXPECTED TO HEAD SOUTHEAST THROUGH THE
AREA. THIS FEATURE WILL ACT AS THE MAIN FOCUS FOR SHOWERS AND
POTENTIALLY STRONG THUNDERSTORMS TO SWEEP ACROSS THE AREA. BETTER
MID LEVEL JET SUPPORTS MORE ORGANIZED CONVECTION ALTHOUGH TIMING
OF THE MAIN PRE-FRONTAL BOUNDARY IFFY AS COULD HAVE SHRA/TSRA
DURING THE MORNING WHICH MAY LIMIT THE SEVERE THREAT LATER. LOOKS
LIKE ENOUGH COVERAGE TO GO WITH LIKELY POPS OUT TO ALONG THE BLUE
RIDGE AND MAINLY HIGH CHANCE FARTHER EAST. SOME OF THIS MAY LINGER
INTO MONDAY EVENING PENDING ORGANIZATION WHICH SUPPORTS KEEPING
CHANCE POPS GOING THRU ABOUT MIDNIGHT NORTH AND MOST OF THE NIGHT
SOUTH. TEMPS LOOK TO DROP OFF A BIT MONDAY AS 85H COOLING TAKES
SHAPE AND MORE CLOUDS/CONVECTION TEND TO LIMIT RISES EXCEPT
PERHAPS OVER THE FAR SE. A BLEND OF GUIDANCE GIVES LOW/MID 90S
EAST AND MAINLY MID/UPPER 80S WEST.
FRONT SPILLS SOUTH INTO THE CAROLINAS TUESDAY FOLLOWED BY SURFACE
HIGH PRESSURE WHICH SHOULD DRY THINGS OUT FROM NORTH TO SOUTH BY
TUESDAY AFTERNOON. MAY LEAVE IN A LOW POP FAR SOUTH IN CASE THE
BOUNDARY SLOWS A LITTLE OTRW DRIER AND SLIGHTLY COOLER FOR
TUESDAY WITH DEWPOINTS QUITE A BIT LOWER.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
TUESDAY NIGHT AND WEDNESDAY THE FRONT TO THE SOUTH DISSPATES WITH
SURFACE HIGH PRESSURE CENTERED OVER THE FORECAST AREA ON WEDNESDAY
MORNING. DEEPER MOISTURE REMAINS CLOSE TO THE NORTHERN NORTH
CAROLINA MOUNTAINS SO WILL KEEP A LOW CHANCE OF SHOWERS AND
THUNDERSTORMS IN FOR WEDNESDAY AFTERNOON AND EVENING.
THURSDAY SURFACE HIGH PRESURE ERAMINS OVER THE SOUTHEAST UNITED
STATES AND HEIGHTS RISE AT 500 MB. THE 500 MB RIDGE WILL BE CENTERED
OVER THE CAROLINAS THURSDAY AND FRIDAY. THIS WILL BRING ABOVE NORMAL
TEMPERATURES AND INCREASED MOISTURE BACK INTO THE AREA THROUGH THE
END OF WEEK. MODELS SHOW NO ORGANIZED FORECING FOR PRECIPITATION SO
DAILY CHANCES THROUGH THE PERIOD WILL BE IN FAVORED AREAS ALONG THE
BLUE RIDGE AND IN THE MOUNTAINS DURING THE AFTERNOON AND EVENING.
&&
.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
SCATTERED CONVECTION WILL BE THE MAIN ISSUE INTO THIS EVENING
DESPITE OVERALL VFR UNDER SCT-BKN CU AND PLENTY OF HAZE ALOFT.
HOWEVER APPEARS THE WESTERN LOCATIONS FROM KBCB INTO SE WVA WILL
HAVE THE BEST CHANCES OF SEEING A TSRA AT ONE OF THE AIRPORTS SO
INCLUDING A VCTS MENTION THERE...WITH CB MENTION ELSW OUTSIDE OF
THE EASTERN LOCATIONS. ANY STORMS WILL WEAKEN AND END THIS EVENING
LEAVING BEHIND ANOTHER FOGGY NIGHT...ESPECIALLY FOR THE WESTERN
LOCATIONS THAT SAW EARLIER SHOWERS. NOT OUT OF THE QUESTION THAT
BLF/LWB AND BCB ALL EXPERIENCE SUB MVFR OR IFR CONDITIONS LATE
TONIGHT.
SUNDAY LOOKS LIKE A REPEAT OF TODAY WITH STORMS DEVELOPING ACROSS
THE WESTERN RIDGES BY MIDDAY AND WITH THE FRONT STAYING NORTH OF
US...THE MAIN THREAT WILL STAY IN THE NRN FORECAST AREA BUT COULD
SEE CONVECTION AREA WIDE AND ESPCLY LATE IN THE DAY AS A TSRA
COMPLEX OR TWO DROPS IN FROM THE NORTH. THUS WILL INCLUDE MORE
CLOUDS ACROSS THE SE WVA SITES THRU MIDDAY SUNDAY BUT HOLD OFF ON
ADDING A CB MENTION FOR NOW.
THE RIDGE BREAKS DOWN SUNDAY NIGHT INTO EARLY NEXT WEEK WITH A
FRONT MOVING IN. THIS FRONT SHOULD BRING A BETTER THREAT OF TSRA
TO MOST OF THE AREA MONDAY. AS COOLER AIR ARRIVES INTO TUESDAY
MORNING THERE SHOULD BE SOME IFR FOG WITH A WET GROUND THEN A DRY
TUESDAY PM FOLLOWS. OTRW LOOKING FOR IMPROVING CONDITIONS WITH VFR
FOR TUESDAY AFTERNOON THRU THURSDAY.
