AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
1124 AM EDT SAT JUL 7 2012

.SYNOPSIS...
STRONG UPPER LEVEL AREA OF HOT HIGH PRESSURE WILL OOZE OVER THE
AREA THIS WEEKEND. THIS HIGH WILL BREAK DOWN AFTER THE WEEKEND...
ALLOWING A SURFACE COLD FRONT TO MOVE SOUTH FROM THE GREAT LAKES
THE FIRST PART OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
AS OF 1045 AM EDT SATURDAY...

ADDED HENRY COUNTY TO HEAT ADVISORY. HEAT INDICES WILL BE CLOSE TO
110F FOR A FEW HOURS IN THE URBANIZED LOCATIONS OF
DANVILLE...MARTINSVILLE AND REIDSVILLE NORTH CAROLINA.

SECOND WEEKEND IN A ROW OF UPPER 90S AND SOME LOWER 100S ACROSS
THE REGION IN THE LOWER ELEVATIONS. DANVILLE APPEARS TO BE THE
ONLY SITE WITH A SAFE RECORD FOR TODAY...ALTHOUGH IT MAY BE CLOSE.
MAV MOS SEEMED TO RUN TOO COOL IN THE SOURCE REGION OF TODAY'S
AIRMASS ACROSS CENTRAL AND SOUTHERN OHIO SO WENT MORE TOWARDS TO
WARMER MET MOS. COULD BE CLOSE TO EXCESSIVE HEAT WARNING CRITERIA
ACROSS THE NC PIEDMONT AND SOUTHSIDE VA ESPECIALLY IN THE CITIES.
MAY HAVE TO ISSUE A QUICK EXCESSIVE HEAT WARNING IF DEWPOINTS
DON'T MIX DOWN INTO THE 60S THIS PM. ALTHOUGH LEFT OUT OF THE
FORECAST THERE COULD BE ONE OR TWO POP UP STORMS TODAY
PARTICULARLY IN THE SW...BUT VERY DIFFICULT TO PINPOINT WHERE
EXACTLY SO WILL JUST KEEP ISOLATED STORMS IN NW NC.

AS OF 710 AM EDT SATURDAY...

UPDATE TO ADD SOME FOG FOR ANOTHER HOUR OVER SE WV INTO PORTIONS
OF SE WV. DELAYED ONSET OF POPS IN THE MTNS OF NC AS WELL...AS THE
LATEST NAM/ECMWF SHOW EVEN LESS LIKELY CHANCES OF STORMS IN OUR
AREA TODAY THANKS TO THE RIDGE ALOFT.

PREVIOUS DISCUSSION...
FORECAST ISSUE TODAY WILL BE THE HEAT. RH THIS AFTERNOON WILL BE
ENOUGH TO SEND HEAT INDEX VALUES AT OR ABOVE 105 IN THE PIEDMONTS
OF NC/VA....THEREFORE WENT AND/OR KEPT HEAT ADVISORY. THE
EXCESSIVE HEAT WATCH FOR BUCKINGHAM WAS CHANGED TO ADVISORY AS
HEAT INDEX SHOULD STAY BELOW 110F. EXPANDED THE ADVISORY WEST TO
COVER AMHERST COUNTY VA AND ROCKINGHAM COUNTY NC. WILL MENTION THE
HOT TEMPS IN THE HWO FURTHER WEST WHERE HEAT INDICES STAY BELOW
105F.

THE CULPRIT FOR THE HEAT IS THE RIDGE ALOFT BUILDING EWD FROM THE
MIDWEST EXTENDING  8H TEMPS HIGH WITH +24 TO +25C ANTICIPATED. THE
WINDS WILL BE WEST TO NW ALTHOUGH SOME SW COMPONENT FOR THE PIEDMONT
IS POSSIBLE. GIVEN THE AIRMASS...THE DEWPOINTS SHOULD STAY JUST LOW
ENOUGH TO PREVENT SURGING HEAT INDICES ABOVE 109.

THUNDERSTORMS TODAY WILL BE MAINLY CONFINED TO THE HIGH COUNTRY OF
NC...BUT SOME MAY START TO FIRE UP AFTER 6 OT 7 PM UP ALONG THE BLUE
RIDGE IF THE CAP CAN BE BROKEN. ALTHOUGH CONFIDENCE NOT HIGH TO
THROW IN POPS ACROSS THIS AREA YET.

SHOULD SEE HIGHS AROUND 100F ACROSS THE PIEDMONT AND CLOSE TO 100 IN
ROANOKE AND PORTIONS OF THE SRN SHENANDOAH VALLEY. THE MTNS WILL
RANGE FROM THE MID 90S VALLEYS TO UPPER 80S AT THE HIGHER
ELEVATIONS. BASED ON FORECAST HIGHS...THINK 1 OR 2 RECORD HIGHS
COULD BE BROKEN THIS AFTERNOON...MAINLY LYH AND BLF AND MAYBE BCB.
SEE CLIMATE SECTION BELOW FOR RECORD HIGHS TODAY AND SUNDAY.

TONIGHT...THE AIRMASS REMAINS UNCHANGED WITH SOME INCREASE IN
DEWPOINTS KEEPING LOWS ABOVE NORMAL. WILL PROBABLY SEE SOME RECORD
WARM LOWS AS WELL ON THE 8TH UNLESS WE GET SOME COOLING
THUNDERSTORMS SUNDAY.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH TUESDAY NIGHT/...
AS OF 325 AM SATURDAY...

FOR SUNDAY...THE AREA WILL EXPERIENCE ONE MORE DAY OF ABOVE NORMAL
HOT TEMPERATURES ACROSS THE REGION. HIGHS AGAIN AROUND THE CENTURY
MARK ARE EXPECTED EAST OF THE BLUE RIDGE...WITH HEAT INDEX VALUES
AROUND A 105 TO 108 ALONG AND EAST OF A MARTINSVILLE TO LYNCHBURG
LINE. THE BIG DIFFERENCE ON SUNDAY...WILL BE AN INCREASED COVERAGE
OF SHOWERS AND STORMS. THESE WILL BE DUE IN PART TO GREATER
INSTABILITY WITH THE APPROACH OF A BACKDOOR COLD FRONT. THIS FRONT
WILL MOVE INTO AND STALL ACROSS THE AREA ON MONDAY.

THE RESULT WILL BE AN EVEN GREATER COVERAGE OF SHOWERS AND STORMS ON
MONDAY WITH LOWER TEMPERATURES TO NEAR NORMAL CONDITIONS FOR THE
SECOND WEEK OF JULY. THE FRONT WILL MAKE LIMITED PROGRESS SOUTH OF
THE AREA BY THE MIDDLE OF THE WEEK. ITS PROXIMITY WILL MEAN A
CONTINUATION OF A BETTER COVERAGE OF SHOWERS AND STORMS...ESPECIALLY
NEAR THE VA/NC BORDER. ALSO...TUESDAY THE AREA CAN EXPECT TO
EXPERIENCE ITS FIRST BELOW NORMAL TEMPERATURES SINCE ABOUT TWO WEEKS
AGO. ANTICIPATE HIGHS IN THE UPPER 70S TO AROUND 80 IN THE
MOUNTAINS...WITH LOW TO MID 80S EAST OF THE BLUE RIDGE.

&&

.LONG TERM /WEDNESDAY THROUGH FRIDAY/...
AS OF 400 PM EDT FRIDAY...

MODELS/ENSEMBLES REMAIN IN GENERAL AGREEMENT WITH THE LARGE SCALE
PATTERN THROUGH THE END OF NEXT WEEK. A MEAN RIDGE WILL RESIDE OVER
THE ROCKIES AND VICINITY MEANWHILE TROFFING DEVELOPS OVER THE NERN
QUADRANT OF THE NATION ON TUESDAY. THE MODELS REMAIN CONSISTENT THAT
COOL DOWN WILL TAKE FORM NEXT WEEK...SHAVING ABOUT 10 DEG C OFF
THE 85H TEMP AND TRIMMING SFC TEMPS TO A MORE TOLERABLE LEVEL.
HIGH TEMPERATURES ON WED-THU WILL BE NEAR TO SLIGHTLY BELOW NORMAL
IN THE UPPER 70S OVER THE MOUNTAINS TO LOW 80S OVER THE PIEDMONT.
HOWEVER PRECIPITATION AND ASSOCIATED CLOUD COVER WILL PLAY A ROLE
IN HOW MUCH WE WARM UP DURING THE DAY.

IN ADDITION GUIDANCE IS NOW INDICATING THAT THE STRONG RIDGE
OVER THE ATLC MAY TRY TO BUILD WWD INTO THE SERN U.S. BY
WED-THU...SERVING TO WEAKEN THE NERN TROF ALOFT AND STALL THE SFC
FRONT THAT WILL MOVE IN EARLY NEXT WEEK. HOWEVER THE BIG QUESTION IS
HOW FAR SOUTH THE FRONT WILL DRIFT BEFORE STALLING. THERE IS
CURRENTLY SOME MODEL DISAGREEMENT WITH THIS AS THE GFS IS STALLING
THE FRONT FURTHER NORTH WITH THE MAIN AXIS OF CONVERGENCE ONLY
MAKING IT TO NORTH CAROLINA BEFORE DRIFTING BACK NORTHWARD...WHEREAS
THE EC PUSHES THE FRONT INTO GA/SC. THE CURRENT FORECAST IS MORE
IN-LINE WITH THE GFS AND POPS HAVE BEEN INCREASED TO THE UPPER
40S/LOW 50S FOR THE WED-THURS AS THE FRONT BECOMES MORE NE-SW
ORIENTED WITH LOW-LEVEL SOUTHERLY UP-SLOPE DEVELOPING ALONG THE BLUE
RIDGE. POPS WILL NEED TO BE ADJUSTED AS THE GFS AND EC COME
INTO ALIGNMENT.

&&

.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
AS OF 715 AM EDT SATURDAY...

FOG THIS MORNING AT LWB/BCB SHOULD BE GONE BY 12-13Z. VFR EXPECTED
TODAY WITH SOME SCT CU POSSIBLE ACROSS THE MTNS. THUNDERSTORM
CHANCES APPEAR MINIMAL AND CONFINED TO THE NC MTNS. EXPECT VFR
CONDITIONS. WITH THE HOT TEMPS TODAY IT SHOULD DRY THE GROUND OUT
MORE...AND WITH NO RAIN EXPECTED...THINK FOG WILL ONLY BE CONFINED
TO A FEW RIVER VALLEYS IN THE MORNING...SO FOR NOW ONLY HAVE LWB
GOING TO 5SM AROUND 10Z SUN.

SUNDAY WILL ALSO BE FAIRLY QUIET YET HOT WITH ISOLATED TSRA IN
THE MTNS.

A FRONT WILL BE SLOWLY PUSHING SOUTH BY LATE SUNDAY STALLING SOUTH
OF US BY EARLY NEXT WEEK. THIS PATTERN SUGGESTS A WETTER SOLUTION
NOW...ESPECIALLY SOUTH OF A BLF-ROA-LYH LINE...BUT WILL SEE IF
TRENDS CONTINUE TO SLOW THE FRONT DOWN MORE OR LIMIT ITS SWD PUSH.
WITH THIS PATTERN...THERE SHOULD BE MORE SHRA/TSRA COVERAGE.

&&

.CLIMATE...
HIGH PRESSURE RIDGE WILL KEEP US HOT THROUGH THE WEEKEND.
