Area forecast discussion, Jul 18, 1:46 PM EDT, 1 hour 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
146 PM EDT THU JUL 18 2013

.SYNOPSIS...
HIGH PRESSURE WILL MAINTAIN HOT AND HUMID CONDITIONS THROUGH
TOMORROW. A COLD FRONT WILL MOVE SOUTHWARD INTO THE AREA...WHICH
WILL STALL OVER THE CAROLINAS AND KEEP THE DAILY THREAT OF
SHOWERS AND THUNDERSTORMS INTO THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 1140 AM EDT THURSDAY...

TEMPERATURES IN THE PIEDMONT ARE ON PACE WITH THE MAV
GUIDANCE...SO HIGHS WERE BUMPED UPWARD ABOUT A DEGREE. CLOUD COVER
CONTINUES TO LINGER OVER SOUTHEAST WEST VIRGINIA AND NORTH OF
ROANOKE...BUT IT SHOULD GRADUALLY FADE DURING THE NEXT FEW HOURS.
HIGHS WERE BUMPED DOWNWARD A DEGREE NEAR LEWISBURG DUE TO THE
PERSISTENT LOW CLOUDS. RADAR HAS SHOWN A COUPLE SHOWERS POP UP IN
AMHERST AND NELSON COUNTIES...SO POPS HAVE BEEN RAISED A LITTLE IN
ANTICIPATION OF MORE SCATTERED ACTIVITY BEGINNING SOON.

AS OF 1020 AM EDT THURSDAY...

TEMPERATURES ARE RISING QUICKLY INTO THE 80S OVER THE PIEDMONT.
WITH MOSTLY SUNNY SKIES AND A HUMID AIR MASS...HEAT INDEX VALUES
SHOULD APPROACH 105 DEGREES THIS AFTERNOON...AS TEMPERATURES
CLIMB INTO THE LOWER TO MID 90S AND DEWPOINTS STAY IN THE LOWER TO
MID 70S. ALTHOUGH THE CRITERIA FOR TIME IN A HEAT ADVISORY IS 3
HOURS...IMPACTS MAY BE A LITTLE MORE THAN NORMAL FOR HEAT
EXHAUSTION DUE TO THE RATHER COOL START TO THIS SUMMER. THUS...A
HEAT ADVISORY WAS ISSUED FOR THE VIRGINIA PIEDMONT EAST OF
DANVILLE AND LYNCHBURG FROM NOON THROUGH 6 PM EDT.

LOW LEVEL CONVERGENCE IS STILL DEPICTED WEST OF THE BLUE RIDGE IN
THE MODELS...BUT NOT MUCH QPF IS SHOWN IN THE LATEST NAM AND RAP
SOLUTIONS. THE HIGHEST POPS WERE PLACED OVER FAR SOUTHWEST
VIRGINIA...SOUTHEAST WEST VIRGINIA...AND THE NORTHWEST NORTH
CAROLINA MOUNTAINS FOR THIS AFTERNOON AND EVENING. STORMS IN THIS
AREA COULD BECOME SEVERE DUE TO A THREAT OF DAMAGING WINDS...AND
POTENTIALLY HEAVY RAINFALL MAY RAISE A LOCALIZED FLASH FLOOD
CONCERN. ALTHOUGH THE BEST CONVERGENCE AND LIFT HAS MOVED WELL
AWAY FROM THE PIEDMONT...THIS HOT AND HUMID AIR MASS WITH UP TO
3000 J/KG OF CAPE IN THE FORECAST MODEL SOUNDINGS AND A WEAK
NORTHEAST FLOW...COULD STILL SPARK A COUPLE ISOLATED STORMS.

AS OF 325 AM EDT THURSDAY...

AS WE HEAD INTO TONIGHT...MODELS SHOWING SOME WEAK DISTURBANCES
MOVING WEST TO EAST ACROSS VA/NC...SO KEEPING SOME SCATTERED TO
ISOLATED COVERAGE AT LEAST INTO MIDNIGHT...WITH SOME OVERNIGHT IN
THE WEST. WITH HUMID AIRMASS IT IS HARD TO COMPLETELY RULE OUT
SHOWERS OR STORMS LASTING INTO THE LATE NIGHT.

FOR HIGHS TODAY MAINTAINED SIMILAR TO PREVIOUS FORECAST WITH MID
TO UPPER 80S MOUNTAINS TO LOWER TO MID 90S EAST. TONIGHT...LOWS
ARE GOING TO BE SIMILAR TO THIS MORNING WITH MID TO UPPER 60S
MOUNTAINS AND LOWER 70S EAST.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/...
AS OF 315 AM EDT THURSDAY...

DURING THIS PORTION OF THE FORECAST PERIOD...SHOWERS AND STORMS WILL
TREND MORE NUMEROUS AND MORE ORGANIZED WITH THE APPROACH AND
SUBSEQUENT ARRIVAL OF A COLD FRONT. WE ARE EXPECTING THE FRONT TO
ARRIVE SUNDAY INTO SUNDAY NIGHT. EACH DAY TEMPERATURES WILL BE
TRENDING SLIGHTLY COOLER THANKS TO MORE CLOUD COVER AND
PRECIPITATION FRIDAY AND SATURDAY...AND THEN ADDITIONALLY BECAUSE OF
AIRMASS CHANGE BY SUNDAY NIGHT WITH THE FRONT TO OUR SOUTH.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
AS OF 1140 AM EDT WEDNESDAY...

BY THIS TIME UPPER RIDGE IS GONE AND TROFFING HAS DEVELOPED OVER THE
NORTHEAST UNITED STATES. LONG WAVE TROF REMAINS OVER THE EAST
THROUGH TUESDAY. GFS CONTINUES TO SHOW A MORE AMPLIFIED UPPER RIDGE
IN THE WEST AND MOVES THE SURFACE FRONT FURTHER SOUTH IN THE
EAST...WHILE THE ECMWF IS LESS AMPLIFIED WITH THE UPPER PATTERN AND
NOT AS FAR SOUTH WITH THE SURFACE FRONT. TAKING A BLEND OF THESE TWO
SOLUTIONS AS RECOMMENDED BY WPC...THE SURFACE FRONT STALLS ACROSS
THE CAROLINAS AND TENNESSEE VALLEY THROUGH WEDNESDAY. DUE TO THE
CHANCE OF SHOWERS AND THUNDERSTORMS BEING IN THE FORECAST FOR A
NUMBER OF DAYS...WILL HIGHLIGHT THREAT OF HEAVY RAIN IN THE
HAZARDOUS WEATHER OUTLOOK.

WHILE 850 MB TEMPERATURES DO NOT CHANGE MUCH...THE CLOUDS AND CHANCE
OF PRECIPITATION WILL LEAD TO NEAR NORMAL TO SLIGHTLY BELOW
TEMPERATURES.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
AS OF 145 PM EDT THURSDAY...

VFR CONDITIONS WITH LIGHT WINDS SHOULD PERSIST THROUGH THIS
AFTERNOON...BUT SOME ISOLATED SHOWERS AND THUNDERSTORMS WILL FIRE
ALONG AND WEST OF THE BLUE RIDGE. VCTS WAS INSERTED FOR
LWB/BLF/BCB/ROA AND LEFT OUT AT LYH/DAN DUE TO LACKING LOW LEVEL
CONVERGENCE IN THE PIEDMONT. AFTER SUNSET...CONVECTION SHOULD
WANE...BUT PATCHY FOG SHOULD DEVELOP AFTER MIDNIGHT. GIVEN THE
TREND OF THE LAST FEW NIGHTS AND THE MOIST GROUND...CONFIDENCE IS
GOOD FOR IFR/LIFR FOG AT LWB AND BCB. MODEL GUIDANCE IS LESS
CONFIDENT FOR THE DEVELOPMENT OF DENSE FOG AT THE OTHER SITES...SO
MVFR/IFR FOG WAS UTILIZED. THE EXCEPTION WAS ROA...WHERE MENTION
OF FOG WAS OMITTED FOR NOW DUE TO MORE OPTIMISTIC GUIDANCE THERE.

VFR CEILINGS AND VISIBILITIES SHOULD RESUME BY FRIDAY MORNING.
HOWEVER...A DAILY THREAT OF AFTERNOON SHOWERS AND THUNDERSTORMS
WILL CONTINUE THROUGH THIS WEEKEND...AS A COLD FRONT MOVES
SOUTHWARD OVER THE AREA. FLYING WEATHER APPEARS MOST PESSIMISTIC
DURING SATURDAY EVENING THROUGH SUNDAY EVENING WHEN THE FRONT
CROSSES OVERHEAD...AND PROVIDES MVFR/IFR CONDITIONS FROM SHOWERS
AND THUNDERSTORMS. LONG RANGE MODELS SHOW THE COLD FRONT STALLING
OVER THE CAROLINAS BY MONDAY...WHICH WOULD KEEP THE THREAT OF
AFTERNOON CONVECTIVE ACTIVITY THROUGH EARLY NEXT WEEK.
