NWS Blacksburg, VA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 24, 3:44 PM EDT, 1 hour 56 minutes earlier.

Area forecast discussion, Jul 24, 3:44 PM EDT, 1 hour 56 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
344 PM EDT SUN JUL 24 2011

.SYNOPSIS...
HIGH PRESSURE ACROSS THE REGION WILL CONTINUE TO WEAKEN AND SLIDE
SOUTH TONIGHT AHEAD OF A COLD FRONT APPROACHING FROM THE
NORTHWEST ON MONDAY. THE FRONT SHOULD DROP SOUTH INTO THE REGION
LATE MONDAY BEFORE DRIFTING INTO THE CAROLINAS MONDAY NIGHT INTO
TUESDAY. COOLER HIGH PRESSURE BEHIND THE FRONT WILL SPILL INTO
THE AREA THROUGH WEDNESDAY...FOLLOWED BY ANOTHER BOUT OF HEAT AS
HIGH PRESSURE ALOFT BUILDS BACK IN FROM THE WEST FOR THE END OF
THE WEEK.
&&

.NEAR TERM /THROUGH MONDAY/...
SHOTGUN PATTERN OF CONVECTION CONTINUES TO INCREASE THIS AFTERNOON
WITH SEVERAL MULTICELLULAR BANDS ONGOING ALONG THE BLUE RIDGE.
HOWEVER SO FAR WEAK CAP ALOFT HAS LIMITED SEVERE POTENTIAL TO
ISOLATED MICROBURSTS BUT GIVEN STRONG HEATING EXPECT COVERAGE TO
GRADUALLY SHIFT EAST TO HIGHER INSTABILITY ALONG/EAST OF THE BLUE
RIDGE INTO THIS EVENING. MOST MODEL GUIDANCE SUPPORTS THIS SCENARIO
SO BASICALLY KEEPING HIGH CHANCE POPS GOING THRU SUNSET WITH
LOCALIZED LIKELYS IN SPOTS. INITIAL BATCH OF CONVECTION SHOULD FADE
OUT THIS EVENING WITH NEXT UPSTREAM COMPLEX NOW WELL TO THE NW
LIKELY TO MAKE A RUN TOWARD THE FAR WEST AFTER DARK. GUIDANCE NOT
TOO AGGRESSIVE IN BRINGING TOO MUCH OF THIS BOWING COMPLEX INTO THE
AREA WITH CORFIDI VECTORS TAKING IT MORE INTO KY. THUS WONT UP POPS
BACK TO LIKELYS WEST BUT BOUNCE TO HIGHER CHANCE TO MATCH BETTER
WITH UPSTREAM THINKING. OTRW THINK CONVECTION AGAIN WASHES OUT TO
SLIGHT POPS OR LESS EAST GIVEN LACK OF FORCING AND LOSS OF HEATING.
SOME FOG AGAIN POSSIBLE BUT MOSTLY PATCHY IN AREAS THAT SAW EARLIER
RAINFALL AND CLEAR OUT BRIEFLY TONIGHT. LITTLE CHANGE TO GOING TEMPS WITH
LOWS SIMILAR TO THE PAST FEW OVERNIGHTS...MOSTLY UPPER 60S TO MID 70S.

BETTER HEIGHT FALLS FINALLY TAKE SHAPE ON MONDAY AS THE MAIN S/W
TROF PASSES ACROSS THE LAKES AND SHOVES THE SURFACE COLD FRONT
TOWARD THE AREA BY AFTERNOON. HOWEVER TIMING OF PRE-FRONTAL
CLDNS/SHRA STILL IN QUESTION AS MODELS HAVE BEST SUPPORT PASSING
NORTH AND DEEPER INSTABILITY TO THE SOUTH AND WEST. HOWEVER DO SEE A
WEAK S/W WORKING IN FROM THE WEST DURING THE AFTERNOON WHICH SHOULD
SUPPORT A LITTLE BETTER COVERAGE IF ENOUGH HEATING DOES DEVELOP.
LATEST NAM HAS THE BEST INSTABILITY ALONG THE BLUE RIDGE EARLY ON
WITH MORE CLOUDS NW...THEN HIGHER CAPES SOUTH AND EAST DURING THE
AFTERNOON WHEN BETTER BOUNDARY LAYER NW FLOW DEVELOPS. THEREFORE
THINKING WILL SEE PERHAPS A MCS FIZZLE OVER THE FAR WEST
EARLY...THEN SCTD COVERAGE BLUE RIDGE THAT EVENTUALLY MESHES INTO A
BROKEN LINE BEFORE JUMPING SOUTH INTO NORTH CAROLINA LATER IN THE
DAY. THIS SPELLS KEEPING LIKELY/HIGH CHANCE POPS WESTERN HALF INTO
THE AFTERNOON...THEN SLIDING SE BY EVENING. WILL INCLUDE AT LEAST
ISOLATED SEVERE POTENTIAL IN THE HWO GIVEN DECENT LAPSES DESPITE
LACK OF MUCH DRY AIR ALOFT. BASICALLY USED A COMP ON TEMPS...LEANING
TOWARD THE WARMER MAV EAST PER MORE INSOLATION/DOWNSLOPE AND THE
COOLER MET MOS WEST WHERE EXPECTING MORE CLOUDS/SHRA EARLY. OTRW
MOSTLY 80S WEST AND LOW/MID 90S ALONG/EAST OF THE BLUE RIDGE.

&&

.SHORT TERM /MONDAY NIGHT THROUGH THURSDAY/...
SHOWER AND THUNDERSTORM ACTIVITY WILL CONTINUE TO BE SCATTERED
ACROSS THE REGION ON MONDAY EVENING AS A COLD FRONT CONTINUES TO
DESCEND SOUTHWARD FROM THE OHIO RIVER VALLEY. WHILE THIS ACTIVITY
WILL DIMINISH AFTER MIDNIGHT AS THE FRONT CONTINUES THROUGH OUR
REGION...WILL STILL EXPECT SPOTTY SHOWERS TO LINGER THROUGH SUNRISE
ON TUESDAY.

BY TUESDAY MORNING...THE COLD FRONT WILL HAVE PUSHED INTO NORTHERN
NORTH CAROLINA. SHALLOW HIGH PRESSURE WILL BUILD INTO OUR REGION
BEHIND THE FRONT...BRINGING SLIGHTLY COOLER AND DRIER AIR WITH IT.
SHOWER AND THUNDERSTORM ACTIVITY WILL BE CONFINED TO THE SOUTHERN
THIRD OF THE REGION...IN THE VICINITY OF THE FRONT...BUT THIS
ACTIVITY WILL BE SPOTTY AT BEST. EXPECT MORE OF THE SAME FOR
WEDNESDAY...AS HIGH PRESSURE SLIDES EASTWARD...BUT REMAINS THE
DOMINANT FEATURE OF OUR FORECAST REGION.

ON THURSDAY...HIGH PRESSURE BEGINS TO MOVE OUT OF OUR AREA...
ALLOWING SOUTHERLY WINDS TO BRING ATLANTIC MOISTURE BACK INTO OUR
REGION. WE ALSO BEGIN TO SEE THE UPPER LEVEL RIDGE...WHICH WAS
RESPONSIBLE FOR OUR EXCESSIVE HEAT OVER THE PAST FEW DAYS...TO BUILD
BACK TOWARD OUR AREA FROM THE WEST. THE PRESENCE OF THE RIDGE WILL
LEAD TO ANOTHER WARMUP ACROSS OUR REGION BEGINNING THURSDAY
AFTERNOON...AS WELL AS A RETURN TO AFTERNOON SHOWERS AND
THUNDERSTORMS.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
THE UPPER LEVEL RIDGE REMAINS IN PLACE ACROSS OUR REGION ON THURSDAY
EVENING GOING INTO FRIDAY...AND WE MAY SEE A RETURN TO HEAT ADVISORY
CONDITIONS ACROSS PORTIONS OF THE PIEDMONT AND SOUTHSIDE VIRGINIA
FOR FRIDAY AND POSSIBLY SATURDAY AFTERNOONS AS HIGH TEMPERATURES
REACH INTO THE UPPER 90S IN THESE AREAS. WE CAN ALSO EXPECT SPOTTY
SHOWER AND THUNDERSTORM ACTIVITY ON FRIDAY...WITH A FEW STRONG
THUNDERSTORMS...HOWEVER RAINFALL CHANCES WILL INCREASE SIGNIFICANTLY
ON SATURDAY EVENING AS A COLD FRONT MOVES INTO OUR AREA FROM THE
UPPER OHIO RIVER VALLEY REGION. AT THIS TIME...THE COLD FRONT IS
EXPECTED TO BECOME STATIONARY ACROSS THE SOUTHERN HALF OF OUR
FORECAST REGION...HELPING TO KEEP OUR TEMPERATURES MAINLY IN THE 80S
TO NEAR 90S FOR SUNDAY...AND KEEPING AN INCREASE CHANCE OF RAIN IN
THE FORECAST HEADING INTO THE NEXT WORKWEEK.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
MAIN THREAT AGAIN WITH THE POTENTIAL TO SEE SCATTERED CONVECTION
MOVE IN THE VICINITY OF ANY OF THE AIRPORTS THRU THIS EVENING AS
STORMS POP UP AND MOVE SLOWLY EAST. BEST AREA FOR MORE ORGANIZED
COVERAGE SEEMS TO BE OVER THE SW ATTM WITH TSRA HAVING A HARD TIME
DEVELOPING OUT TO...AND EAST OF THE BLUE RIDGE PER WESTERLY FLOW
ALOFT. LATEST SHORT TERM MODEL GUIDANCE SUGGESTS MORE COVERAGE
UNZIPPING ALONG THE WEST SIDE OF THE BLUE RIDGE...THEN SLOWLY
SAGGING EAST LATER BEFORE FADING OUT OVER THE SE THIS EVENING.
THEREFORE WILL INCLUDE A VCTS MENTION ALONG THE KBLF TO KROA
CORRIDOR AND INCLUDE CB ELSW WHERE CHANCES APPEAR TO BE LESS. OTRW
MAINLY VFR UNDER SCT-BKN CU FIELDS OUTSIDE CONVECTION THIS
AFTERNOON WITH WEST TO NW SFC WINDS AROUND 10 KTS OR LESS.

THE RIDGE BREAKS DOWN TONIGHT INTO MONDAY WITH A FRONT MOVING IN.
WILL LIKELY STILL HAVE SOME LEFTOVER SHRA/TSRA SE THIS EVENING AND
PERHAPS NW EARLY ON AND AGAIN LATE AS ANOTHER UPSTREAM TSRA
COMPLEX MAKES A RUN BUT WONT INCLUDE ANY ADDED CB/VCTS MENTION
ATTM. THINK SLIGHTLY LOWER DEWPOINTS AND LIGHT WEST WINDS MAY
AGAIN COMBO WITH HIGH/MID CLOUDS TO LIMIT WIDESPREAD IFR IN
FOG/STRATUS. HOWEVER LOW CONFIDENCE SO ONLY INCLUDING SOME
REDUCTIONS IN VSBY TO BRIEF IFR/MVFR LATE TONIGHT IN THE VALLEY
LOCATIONS AND COULD BE WORSE IF RAINFALL ENDS UP MORE WIDESPREAD
THIS AFTERNOON.

THE FRONT SHOULD BRING A BETTER THREAT OF TSRA TO MOST OF THE
AREA MONDAY AND COULD SEE SOME EARLY CONVECTION DEVELOP SE WVA
MONDAY MORNING. HOWEVER MAIN TIMING LOOKS TO BE MONDAY AFTERNOON
ESPCLY FROM THE BLUE RIDGE SOUTH AND EAST WHERE BETTER INSTABILITY
WILL EXIST. ACTUAL FRONT PUSHES THROUGH MONDAY NIGHT AND 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 BY TUESDAY AFTERNOON
THRU LATE WEEK.
