Damaging Winds in North Carolina, July 24 to 25, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
126 PM EDT TUE JUL 24 2012

.SYNOPSIS...
HIGH PRESSURE ALOFT WILL GRADUALLY SHIFT FROM THE CENTRAL U.S.
INTO THE SOUTHEAST U.S. THROUGH THE END OF THE WEEK. NORTHWEST
FLOW WILL REMAIN FIRMLY ENTRENCHED ON THE NORTH SIDE OF THE HIGH
FROM THE UPPER MIDWEST INTO THE MID-ATLANTIC REGION. A SERIES OF
DISTURBANCES WILL TRACK ACROSS THE REGION IN THIS NORTHWEST
FLOW...IMPINGING ON A WARM TO HOT AND HUMID AIR MASS AND CONTINUE
THE DAILY THREAT FOR SHOWERS AND THUNDERSTORMS.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 109 PM EDT...
SEVERE THUNDERSTORM WATCH 510 IN EFFECT UNTIL 8 PM FOR ENTIRE CWA.
UPDATED ISC GRIDS AND FORECAST FOR WATCH.

AS OF 1209 PM EDT TUESDAY...

WILL BE DOING A SPECIAL SOUNDING THIS AFTERNOON. MODIFIED POPS FOR
LATEST MODEL TRENDS.

AS OF 1021 AM EDT TUESDAY...
SPC HAS ADVERTISED...IN SWODY1...THE SLIGHT RISK FOR SEVERE
THUNDERSTORMS FOR THE ENTIRE CWA THIS AFTERNOON INTO TONIGHT. THE
MAIN THREATS ARE FOR DAMAGING WINDS...HAIL AND HEAVY DOWNPOURS.
DAMAGING WINDS MAY BE EXPECTED WITH THESE STORMS GIVEN THE STRONG
INSTABILITY IN CONJUNCTION WITH STEEP LOW-LEVEL LAPSE RATES. WILL
MAINTAIN THE HIGHEST POPS AND ENHANCED WORDING IN THE WEST.

RAISED POPS IN THE NORTHWEST FOR CONVECTION AS SEEN ON KFCX 88D
LOOP. THIS MORNING WRF-ARW-RNK AND WRF-NMM-SPC DEVELOPED NUMEROUS
SHOWERS AND THUNDERSTORMS IN THE WEST BY 18Z THEN MOVING THE
CONVECTION SOUTHEAST INTO THE PIEDMONT. ANOTHER THUNDERSTORM
COMPLEX DROPS QUICKLY SOUTH ACROSS WESTERN PORTIONS OF CWA FROM
23Z-03Z THIS EVENING INTO TONIGHT. RAISED HIGH TEMPERATURES WITH
WARM START THIS MORNING AND LIMITED CLOUD COVER IN THE EAST. WILL
MAKE ADDITIONAL CHANGES AS DAY PROGRESSES.

AS OF 450 AM EDT TUESDAY...

MAIN CONCERN AGAIN THIS PERIOD WILL THE THREAT FOR THUNDERSTORMS
THIS AFTERNOON AND TONIGHT. AN IMPRESSIVE LATE JULY DISTURBANCE
WILL TRACK IN NORTHWEST FLOW ALOFT FROM THE OHIO VALLEY TOWARD
THE MID-ATLANTIC REGION TODAY. THIS SYSTEM WILL REACH THE WV/VA
REGION DURING PEAK HEATING. MODELS IN GOOD AGREEMENT OF A
THUNDERSTORM COMPLEX...POTENTIALLY AN MCS...DEVELOPING ACROSS
OH/WV DURING THE MORNING...TRANSLATING S-SSW THROUGH THE
AFTERNOON/EARLY EVENING HOURS. THE UPPER FLOW IS SLIGHTLY MORE
AMPLIFIED TODAY THAN IT WAS MONDAY...HINTING AT A BETTER BACK
BUILDING POTENTIAL FOR THE THUNDERSTORM ACTIVITY. CONSEQUENTLY...THE
FOCUS BULLSEYE FOR CONVECTION TODAY APPEARS TO BE ALONG AND WEST OF
THE I-77 CORRIDOR...WITH THE BRISTOL-ABINGDON AREA APPEARING TO BE IN
THE CENTER OF ANY POTENTIAL MCS. DRIER AIR BEGINS TO ADVECT SW INTO
THE NORTHERN PART OF THE CWA TOWARD EVENING. WITH THIS THINKING IN
MIND...HAVE ADVERTISED LIKELY TO CATEGORICAL POPS GENERALLY FROM
BLF-MKJ...W AND SW...WITH CHC POPS TO THE EAST. THE LOWEST POPS ARE
ACROSS THE PIEDMONT REGION. SPC HAS A SLIGHT RISK ADVERTISED FOR THE
ENTIRE CWA...BUT AGAIN THINKING IS THAT THE MAIN THREAT FOR SVR WILL
BE ACROSS OUR FAR S WV...SW WV...AND NW NC COUNTIES. IF THE MCS
BECOMES MORE ORGANIZED THAN CURRENTLY EXPECTED...WE COULD BE DEALING
WITH ANOTHER DERECHO AND A MORE WIDESPREAD DAMAGING WIND EVENT FOR
AREAS EAST OF THE ALLEGHANYS AS WELL. AS SUCH...SPC IS HINTING AT A
POTENTIAL MODERATE RISK IF THIS BECOMES EVIDENT LATER IN THE DAY.
THE HAIL THREAT SHOULD BE MOSTLY CONFINED TO AREAS WEST OF I-77
GIVEN CURRENT THINKING. CONSIDERING ALL OF THESE FACTORS...HAVE
CONFINED MENTION OF SVR IN THE GRIDS/ZONES TO THE AREAS MOSTLY WEST
OF I-77 FOR THIS AFTERNOON/EVENING.

NOT VERY CONFIDENT ABOUT MAX TEMPS TODAY...WITH PERSISTENCE NOT
PARTICULARLY HELPFUL. WIDESPREAD AFTERNOON CONVECTION MON PUT A LID
ON HEATING ACROSS MUCH OF THE CWA. ABUNDANT CLOUD COVER ACROSS ALL
BUT THE PIEDMONT AND CONVECTIVE POTENTIAL SHOULD ALSO LIMIT
HEATING TODAY AS WELL...BUT THE PIEDMONT AREAS SHOULD SEE
CONSIDERABLY MORE SUN AND THUS A GOOD 5 DEGREES WARMER THAN ON
MON. HAVE STAYED ON THE COLD SIDE OF MAV/MET MOS...BUT A GOOD 5
DEGREES WARMER THAN MON.

ANOTHER CONCERN TODAY WILL BE WIND. A SIGNIFICANT LATE JULY LOW-
LEVEL WESTERLY JET IS EVIDENT. IN FACT...THE HIGHER ELEVATIONS
ALREADY SEEING 10KT OR BETTER WINDS EVEN AT THIS HOUR. A SURE SIGN
OF A WINDY DAY. 850MB WINDS ARE 25-30KTS OR BETTER MUCH OF THE
DAY...AND WITH HEATING...THESE WINDS WILL MIX DOWN TO THE GROUND.
THIS ALSO AROUSES EVEN MORE CONCERN FOR DAMAGING WINDS WITH
THUNDERSTORMS.

OVERNIGHT AND INTO EARLY WED...MODELS IN GOOD AGREEMENT AGAIN THAT
LEFT OVER MCS CONVECTION WILL EVOLVE INTO A WARM ADVECTION
CONVECTIVE REGIME...WITH SHRA/TSRA ACTIVITY SPREADING BACK TO THE
NE TOWARD THE NEW RIVER VALLEY/BCB/ROA TOWARD MORNING. THUS...HAVE
LEFT LOW CHC POPS IN FOR THESE AREAS OVERNIGHT...WITH AGAIN THE
MAIN FOCUS OF THIS ACTIVITY ALSO REMAINING WEST OF I-77 THROUGH
THE NEAR TERM. ALTHOUGH UNUSUAL FOR SUCH TO OCCUR...THIS PATTERN
CERTAINLY APPEARS POSSIBLE GIVEN THE MOIST...UNSTABLE AIR
REMAINING IN PLACE ACROSS THE REGION AND CONTINUED UNSTABLE NW
FLOW ALOFT. CLOUDS AND HIGH DEWPOINTS WILL AGAIN LIMIT COOLING
TONIGHT...WITH MOST AREAS AOA 70F ONCE AGAIN. SLIGHTLY
COOLER/DRIER AIR WILL FILTER INTO THE FAR NORTHERN PARTS OF THE
CWA...SO A FEW MORE 60S CAN BE EXPECTED FROM LWB-LYH...NORTHWARD.

&&

.SHORT TERM /WEDNESDAY THROUGH FRIDAY/...
AS OF 430 AM EDT TUESDAY...

WEAK COLD FRONT WILL SETTLE ACROSS THE EXTREME SW PORTION OF THE
CWA THEN MOVE BACK NORTH OF THE REGION INTO WEDNESDAY NIGHT. THE
EXTRA CLOUDS ALONG THE BOUNDARY WILL CREATE A DIFFERENTIAL HEATING
BOUNDARY WHICH SHOULD BE THE CATALYST FOR SHOWERS AND STORMS
MAINLY ACROSS THE SW ON WEDNESDAY. THE BLOWTORCH OPENS UP ON
THURSDAY WITH H85 TEMPS IN THE LOW +20S AND A DOWNSLOPING WARMING
WIND...HAVE FORECASTED 100F FOR ROA AND DAN. LIKE THE END OF
JUNE...SEEMS AS IF THE 2M TEMPS FROM THE MODELS PER HPC HAVE BEEN
RUNNING A LITTLE COOL...THUS WENT A DEGREE OR TWO ABOVE GUIDANCE
FOR MAX T. RECORD FOR JUL 26 AT ROA IS 101F FROM 1930 AND AT DAN
IS 99F FROM 1987. DRY AND WARM ALOFT SUCH THAT STORMS SHOULD
REMAIN ISOLATED TO SCATTERED WITH THE BEST CHANCE ALONG THE
SOUTHERN BLUE RIDGE. DEEP MIXING WITH WINDS GUSTING TO 20 MPH AT
TIMES OFF THE RIDGES SHOULD ALLOW THE DEWPOINT AT ROA TO MIX BELOW
GUIDANCE...SUCH THAT HEAT ADVISORY CRITERIA MAY NOT BE MET.
HOWEVER...A SLIGHT SOUTHERLY COMPONENT ACROSS THE PIEDMONT AND
SOUTHSIDE MAY KEEP DEWPOINTS THERE CLOSE TO 70F ALL DAY...WHICH
WOULD PUT APPARENT TEMPS INTO HEAT ADVISORY CRITERIA. WILL KEEP
HWO MENTION. STORMS MAY DEVELOP WELL OUT AHEAD OF A COLD FRONT
MOVING THROUGH THE OHIO VALLEY ON FRIDAY BUT THE MODEL QPF FIELDS
DO HINT THAT MUCH OF THIS CONVECTION WILL CRUMBLE UPON CROSSING
THE MOUNTAINS. IN ADDITION...MODELS MAY ALSO BE INDICATING THAT IT
IS TOO WARM ALOFT/CAPPED THAT FAR EAST OF THE COLD FRONT FOR A
LINE OF CONVECTION TO SURVIVE INTO THE ROANOKE VALLEY OR PIEDMONT.
DEPENDING UPON THE TIMING OF THE STORMS AND CLOUDS...FRIDAY MAY BE
NOT TOO MUCH COOLER THAN THURSDAY...ALTHOUGH H85 TEMPS ARE A
COUPLE DEGREES COLDER ON FRIDAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
AS OF 1110 AM EDT TUESDAY...

AMPLIFIED HIGH LATITUDE PATTERN REMAINS THIS PERIOD WITH OUR AREA
SEEING A TROUGH DIGGING ACROSS THE MID ATLANTIC PUSHING A FRONT
THROUGH INTO THE CAROLINAS BY SAT NIGHT. THE QUESTION REMAINS
WHETHER THIS FRONT WILL MAKE IT THIS FAR SOUTH GIVEN THE SUMMER
PATTERN. MODELS SHOW ENOUGH AGREEMENT THAT LEAST THE NRN HALF OF THE
FORECAST AREA WILL SEE LOWER DEWPOINTS/HUMIDITY ARRIVING THE 2ND
HALF OF THE WEEKEND...BUT HEIGHTS START BUILDING AGAIN BY NEXT WEEK.
WILL KEEP THE TEMPS WARM BUT SEASONAL AFTER FRONTAL PASSAGE SAT
NIGHT. THE COLD FRONT SHOULD HAVE ENOUGH FORCING FOR SCATTERED
CONVECTION BUT THE FLOW SHOWS POTENTIAL FOR LEE SIDE DRYING.

THE OVERALL FORECAST WILL KEEP POPS AT A MINIMUM SUN-MON WITH
ISOLATED MTN CONVECTION THEN ANOTHER SHORTWAVE LOOKS TO MOVE INTO
THE AREA BY TUESDAY BUT WILL STILL KEEP POPS IN THE SLIGHT CHANCE
AREA.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
AS OF 1220 AM EDT TUESDAY...

THUNDERSTORMS AND WINDS WILL HINDER AVIATION OPERATIONS THIS
AFTERNOON INTO TONIGHT. AMPLIFYING UPPER FLOW WITH CENTRAL TO MS
VALLEY UPPER RIDGE AND DEEPENING NE U.S. UPPER TROUGH WILL ALLOW
FLOW TO VEER TO MORE NW ACROSS THE REGION THIS TAF VALID PERIOD.

SHORTWAVE WILL TRACK SOUTHWARD ACROSS THE REGION THIS AFTERNOON INTO
THIS EVENING. THIS UPPER DISTURBANCE WILL ENHANCE THUNDERSTORM
DEVELOPMENT. THE BEST POTENTIAL FOR DAMAGING WIND GUSTS REMAINS
ACROSS THE WEST...ESPECIALLY WEST OF I-77. BEST CHANCE OF A
THUNDERSTORM AT A TAF SITE WILL OCCUR AT BLF. BUT...ALL TAF SITE
HAVE THE POTENTIAL FOR THUNDERSTORMS THIS AFTERNOON INTO TONIGHT.

OTHER CONCERN TODAY WILL BE GUSTY WEST WINDS AS STRONG WESTERLY
LOW-LEVEL JET...FOR LATE JULY...ASSOCIATED WITH UPPER
DISTURBANCE...TRACKS ACROSS THE AREA AND MIXES DOWN TO THE SFC.
WINDS ARE GUSTING AT THE HIGHER ELEVATIONS. AS USUAL...ROA WILL
BE THE MOST IMPACTED WITH THESE WINDS...WITH AFTERNOON AND EVENING
WINDS SUSTAINED OF 15KTS WITH GUSTS OF 25-30KTS NOT OUT OF THE
QUESTION. ELSEWHERE...EXPECT MOSTLY 10-12KTS WITH GUSTS OF
17-20KTS. GUSTY WINDS ARE POSSIBLE NEAR ANY THUNDERSTORM.
WINDS WILL DIMINISH CONSIDERABLY AFTER 00Z...BUT REMAIN WNW
THROUGH TAF VALID PERIOD.

WARM ADVECTION PATTERN SETS UP FROM SW TO NE OVERNIGHT WITH RETURN
FLOW AND MOISTURE. CONSEQUENTLY...HAVE ADVERTISED BKN MID LAYER
CLOUDS AND CARRIED VCSH MUCH OF THE NIGHT WEST OF LWB-ROA-DAN.
OUTSIDE TSRA AREAS THROUGH TAF VALID PERIOD...VFR SHOULD BE THE RULE
WITH CIGS AOA 050 AND VSBYS AOA 7SM.

LONG TERM AVIATION OUTLOOK FROM EARLIER DISCUSSION...

NW FLOW ALOFT LOOKS TO PERSIST THROUGH WEDNESDAY...RESULTING IN
ADDED BOUTS OF SHRA/TSRA DURING THE PERIOD. UPPER RIDGE BUILDING
IN MAY TEND TO HOLD TSRA TO THE NORTH ON THURSDAY BEFORE ANOTHER
WEAK COLD FRONT DRIFTS IN FROM THE NORTH LATER FRIDAY INTO
SATURDAY. THIS BOUNDARY WILL AGAIN BRING BETTER CHANCES FOR
SHRA/TSRA AND PERIODIC SUB-VFR CONDITIONS BY WEEKS END. OTHERWISE
EXPECTING VFR CONDITIONS OUTSIDE OF ANY PERIODS OF
THUNDERSTORMS...AND CONTINUED LATE NIGHT FOG WEDNESDAY THROUGH
SATURDAY.
