Damaging Wind and Heavy Rain in Virginia, July 21, 2013

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
1022 AM EDT SUN JUL 21 2013

.SYNOPSIS...
A WEAK COLD FRONT WILL DRIFT SOUTHEAST TOWARD THE AREA
TODAY...BEFORE STALLING OVER OR JUST NORTH OF THE REGION TONIGHT
INTO MONDAY. THE PROXIMITY OF THIS FRONT WILL INCREASE THE THREAT
FOR SHOWERS AND THUNDERSTORMS INTO EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 1015 AM EDT SUNDAY...

LATEST ROUND OF SURFACE OBSERVATIONS AND RADAR TRENDS INDICATES
THAT A WEAK COLD FRONT REMAINS STALLED NEAR THE OHIO RIVER THIS
MORNING. AN UPPER DISTURBANCE RIDING NEAR THE FRONT IS TRIGGERING
SHOWERS AND A FEW THUNDERSTORMS ACROSS CENTRAL WEST VIRGINIA...
WITH THIS ACTIVITY EXPECTED TO ENTER GREENBRIER AND SUMMERS
COUNTIES SHORTLY AFTER 10 AM. THIS AREA OF CONVECTION IS
SMALL...BUT ALSO SLOW MOVING...AND A FEW LOCATIONS IN THESE
COUNTIES MAY PICK UP A QUICK ONE HALF TO THREE QUARTERS OF AN INCH
OF RAIN.

EXPECT THE COLD FRONT WILL ATTEMPT TO SHIFT SOUTHEAST TOWARD THE
REGION TODAY AS THE DISTURBANCE CONTINUES TO THE EAST. MOISTURE
POOLING AHEAD OF THE APPROACHING FRONT WILL RESULT IN A GREATER
CONCENTRATION OF SHOWER AND THUNDERSTORM ACTIVITY ACROSS PARTS OF
SOUTHEAST WEST VIRGINIA. BELIEVE THE GREATEST THREAT WILL BE IN
THE FORM OF HEAVY RAIN...AND POSSIBLY LOCALIZED FLOODING...BUT
OTHERWISE DO NOT EXPECT MUCH IN THE WAY OF ORGANIZED SEVERE
THUNDERSTORM ACTIVITY. STILL HOLDING OFF ON A FLASH FLOOD WATCH AS
HEAVY RAIN HAS BEEN HIT AND MISS ACROSS THE NORTHWEST THE PAST
COUPLE OF DAYS...AND IS EXPECTED TO REMAIN SO TODAY.

ELSEWHERE...RAINFALL DEVELOPMENT WILL BE MORE LINKED TO DAYTIME
HEATING...WITH SPOTTY SHOWERS AND THUNDERSTORMS DEVELOPING ALONG
THE RIDGES DURING EARLY AFTERNOON...AND SPREADING ACROSS THE
PIEDMONTS BY LATE AFTERNOON OR EARLY EVENING. CLOUD COVER WAS THIN
TO START THE DAY...AND SUNSHINE HAS ALLOWED FOR RAPID WARMING OF
TEMPERATURES THIS MORNING...AND WOULD NOT BE SURPRISED TO SEE A
FEW STORMS PULSE UP QUICKLY LATER TODAY...BECOMING STRONG TO
SEVERE...SOUTH OF THE INTERSTATE 81 CORRIDOR.

COLD FRONT WILL REMAIN NORTH OF THE AREA TONIGHT...AND EXPECT MOST
OF THE SHOWER AND THUNDERSTORM ACTIVITY TO DIMINISH AFTER SUNSET
WITH THE LOSS OF DAYTIME HEATING...ALTHOUGH WILL KEEP HIGHER
CHANCES ACROSS THE MOUNTAINS AS WEAK UPPER DISTURBANCES PASS FROM
THE WEST. CONTINUED FETCH OF TROPICAL MOISTURE WILL KEEP OVERNIGHT
LOWS ON THE MILD SIDE...GENERALLY IN THE MID 60S TO LOW 70S.

&&

.SHORT TERM /MONDAY THROUGH WEDNESDAY/...
AS OF 331 AM EDT SUNDAY...

A POSITIVE-TILTED UPPER LEVEL TROUGH WILL ENTER THE OHIO VALLEY ON
MONDAY. THIS SYSTEM PLUS AFTERNOON CONVECTION...WILL HELP PUSH A
WEAK COOL FRONT ACROSS THE REGION MONDAY NIGHT AND TUESDAY. THIS
FRONT MAY WASH OUT BEFORE CROSSING THE BLUE RIDGE OR GET ABSORBED
INTO A SURFACE WAVE LINGERING IN THE NC/VA COASTAL PIEDMONT ON
TUESDAY. DESPITE THE PASSING OF THIS FRONTAL BOUNDARY...THETA-E WILL
REMAIN HIGH KEEPING THE REGION IN A HUMID AIR MASS. MODEL PWATS ARE
FORECASTED TO ALSO REMAIN HIGH AND AROUND 2 STANDARD DEVIATIONS
ABOVE NORMAL (2.00 INCHES). STEERING FLOW WILL BE A LITTLE STRONGER
THAN THE LAST COUPLE OF DAYS...BUT STILL NOT FAST ENOUGH TO LIMIT
FLASH FLOOD THREAT. IF ANY ONE STORM COULD EFFECTIVELY CONVERT THIS
MOISTURE INTO RAINFALL...LOCALIZE FLASH FLOODING WILL BE POSSIBLE.
TRAINING OF CELL WILL LIKELY PRODUCE THE HIGHER FLASH FLOOD THREAT
MONDAY AND TUESDAY. ANTECEDENT CONDITIONS HAVE IMPROVED OVER THE
WEEKEND WITH SPOTTY SHOWERS AND CONSIDERING TIME OF YEAR...FLOODING
MAY JUST BE ISOLATED. WE WILL CONTINUE TO MONITOR THE SITUATION WITH
EACH FORECAST PACKAGE WITH POSSIBLE FLASH FLOOD WATCHES BEING ISSUED
FOR ALL OR PORTION OF THE FORECAST AREA.

HEIGHTS WILL LOWER AS THE UPPER LEVEL TROUGH APPROACHES THE AREA.
WITH LOWER HEIGHTS COMES SLIGHTLY COOLER TEMPERATURES ALOFT AND AN
INCREASE CHANCE FOR HAIL. MELTING HAIL AND WATER LOAD SHEDDING MAY
ALSO LEAD TO WET MICROBURST EACH AFTERNOON AND EVENING. IN THE SHORT
OF IT...SEVERE CHANCES ARE ON THE INCREASE MONDAY AND TUESDAY WITH
PULSE ENVIRONMENT GIVING WAY TO MORE CELLS CONGEALING INTO SLOW
MOVING LINE SEGMENTS. CONVECTION MAY ALSO LINGER DEEP INTO THE NIGHT
AND START EARLIER IN THE MORNING WITH WEAK SHORT WAVES TRACKING OVER
THE REGION EACH PERIOD.

TUESDAY NIGHT INTO WEDNESDAY...WINDS BECOME MORE WESTERLY AS A
STRONGER SHORT WAVE TRACKS NORTHEAST OF THE AREA. THIS WESTERLY FLOW
SHOULD REDUCE THE THREAT OF SHOWERS AND THUNDERSTORMS.
HOWEVER...HUMIDITIES WILL REMAIN HIGH AS A SECONDARY FRONT WITH
DRIER AIR STALLS ACROSS THE SOUTHERN OHIO VALLEY.

WITH BOTH AN INCREASE IN AREAL COVERAGE AND DURATION OF
SHOWERS...AFTERNOON TEMPERATURES WILL LIKELY BE CLOSER TO NORMAL
THROUGH THE FIRST PART OF THIS WEEK. MUGGY CONDITIONS WILL LIKELY
KEEP TEMPERATURES 3F-6F WARMER THAN NORMAL DURING THE OVERNIGHT
PERIOD.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
AS OF 1140 AM EDT SATURDAY...

UPPER TROF OVER THE EASTERN UNITED STATES DEEPENS WITH TIME. LOOKING
AT ONLY SUBTLE DROPS IN 500 MB HEIGHTS OVER THE FORECAST AREA. 850
MB WINDS BECOME NORTHWEST TUESDAY NIGHT AND WEDNESDAY WITH 850 MB
TEMPERATURES AROUND +16...SLIGHTLY COOLER THAN THIS WEEK. ECMWF
FORECAST RELATIVE HUMIDITIES IN THE 700-300 MB LAYER SHOW DRY AIR
COMING INTO THE REGION NOON THURSDAY. WILL HAVE A LOWER
PROBABILITY OF PRECIPITATION IN THE FORECAST FOR FRIDAY AND
SATURDAY EXPECTING THE FRONT TO BE WELL SOUTH OF THE COUNTY
WARNING AREA IN THAT TIME FRAME.

&&

.AVIATION /14Z SUNDAY THROUGH THURSDAY/...
AS OF 645 AM EDT SUNDAY...

FRONT STILL NORTH OF THE OHIO RIVER CONTINUES TO RESULT IN WIDELY
SCATTERED CONVECTION PASSING NW OF KLWB EARLY THIS MORNING. OTRW
VALLEY LOCATIONS HAVE SEEN SOME FOG FILL IN EARLY ON WITH A PERIOD
OF IFR TO LIFR POSSIBLE MAINLY KLWB AND KBCB IN THE NEXT HOUR OR
TWO. ALSO LOW LEVEL MOISTURE HAS AGAIN SLID NORTH TO AROUND KDAN
WITH A SPELL OF MVFR/IFR POSSIBLE IN FOG/STRATUS BEFORE THIS BURNS
OFF BY MID MORNING. ELSW WILL INIT VFR IN JUST SOME DEBRIS MID
CLOUDS AND SOME STRATO-CU WEST. EXPECT MOST SHRA EARLY ON TO
REMAIN NORTH/WEST OF KLWB BUT INCLUDING A VCSH MENTION BY 10 AM
IN CASE A FEW MAKE IT FARTHER EAST.

CONVECTION LOOKS TO BECOME MORE WIDESPREAD ESPCLY WESTERN HALF BY
MIDDAY AS THE COLD FRONT SLIPS SOUTH TOWARD THE AREA THIS
AFTERNOON...WITH LOWER CIGS AND VSBYS LIKELY AT TIMES. HOWEVER
TIMING/COVERAGE REMAINS A BIT MORE IFFY WITH GUIDANCE SHOWING BEST
COVERAGE CLOSER TO THE FRONT ACROSS THE FAR NW AND ONLY SCATTERED
NATURE TSRA FARTHER SE ALONG THE BLUE RIDGE UNTIL LATER IN THE
DAY. FOR NOW WILL INCLUDE SOME MVFR PREVAILING CONDITIONS IN
SHRA/TSRA ESPCLY WESTERN SITES...AND KEEP A VCTS MENTION ELSW
WITHIN THE PREVAILING SHRA CATEGORY. SHOWERS MAY LINGER INTO THIS
EVENING WITH A WAVE PASSING JUST NORTH SO KEEPING A VCSH MENTION
GOING A FEW HOURS PAST SUNSET.

MODELS CONTINUE TO DEPICT THE STALLED FRONT REMAINING OVER/NEAR
THE AREA INTO EARLY NEXT WEEK...ONLY TO HAVE YET ANOTHER COOL FRONT
AFFECT THE REGION BY MIDWEEK. AS A RESULT...PERIODIC ROUNDS OF
MAINLY DIURNALLY DRIVEN SHOWERS AND STORMS WILL LIKELY OCCUR WITH
ANY SHORT LIVED VFR REPLACED BY AFTERNOON/EVENING MVFR/IFR IN
CONVECTION AND OVERNIGHT FOG MON-THU. HOWEVER APPEARS THE BETTER
CHANCES AT MORE WIDESPREAD SHRA/TSRA WILL COME MONDAY AFTERNOON
INTO TUESDAY AS ANOTHER WAVE DROPS SE ALONG THE INITIAL FRONT.
