AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
402 AM EDT WED MAY 27 2009
.SYNOPSIS...
DEEP TROPICAL MOISTURE WILL CONTINUE TO STREAM NORTH INTO THE REGION
THROUGH THURSDAY. THIS IN COMBINATION WITH A WEAK FRONT TO THE NORTH
WILL PRODUCE ROUNDS OF SHOWERS AND THUNDERSTORMS THROUGH FRIDAY
MORNING. DRIER WEATHER SHOULD MAKE A RETURN BEHIND A PASSING COLD
FRONT OVER THE WEEKEND.
&&
.NEAR TERM /THROUGH TONIGHT/...
SHOWERS AGAIN REMAIN TENACIOUS OVER THE FAR SW THIS MORNING AS
BANDS CONTINUE TO REDEVELOP UNDER WEAK UPSLOPE FLOW AIDED BY DEEP
TROPICAL RH AND NOCTURNAL JET. EXPECT THIS SCENARIO TO PERSIST
INTO AT LEAST DAYBREAK ESPCLY WITH SOME LINKAGE TO WEAK S/W SEEN
ON VAPOR LOOP COMING ACROSS EASTERN TN. HOWEVER UNDER LACK OF
INSTABILITY APPEARS HEAVIEST RAIN WONT BE ABLE TO GO TOO FAR
NORTH/EAST EARLY ON SO TRIMMING BACK PART OF THE WATCH TO MAINLY
INCLUDE THE BLUE RIDGE THRU 12Z. MAY ALSO NEED TO THROW IN THE NW
NC MOUNTAINS INTO THE WATCH BEFORE RELEASE IF CURRENT TRAINING
BANDS CONTINUE. OTRW COMPLEX SCENARIO PERSISTS TODAY WITH WEAK LOW
OFF THE CAROLINAS...BACKDOOR BOUNDARY ACROSS THE NE CWA AND NEXT
UPSTREAM COLD FRONT SLOWLY APPROACHING FROM THE WEST BY TONIGHT.
HOWEVER CONNECTION WITH THE DEEPER TROPICAL RH FROM THE SE WILL
SLOWLY WANE DURING THE DAY AS FLOW SLOWLY VEERS MORE SOUTHERLY AND
UPPER FOCUS SHIFTS TO THE WEST WITH WEAK S/W PASSING AHEAD OF THE
ARRIVING PREFRONTAL SHRA LATE. THEREFORE ADJUSTED POPS UP TO
ACCOUNT FOR EARLY SHRA WEST/SW AND THEN KEPT OVERALL LIKELYS WEST
PER WRF AND CHANCE SE WHERE COVERAGE SHOULD BE MORE ISOLATED TO
THE WEST OF THE OFFSHORE LOW. LOWERED TEMPS SOME IN THE EAST GIVEN
MORE EAST/NE FLOW WHILE THE WEST LIKELY WARMER WITH SOME LATE
MORNING/AFTERNOON BREAKS SIMILAR TO TUE.
TRAJECTORIES FINALLY TURN MORE SW ALOFT OVERNIGHT IN ADVANCE OF
THE UPSTREAM 5H TROF AND ASSOCIATED COLD FRONT THAT SHOULD BE
NEARING THE OHIO RIVER BY THU MORNING. GUIDANCE KEEPS WHATS LEFT
OF SHRA AXIS OVER THE WEST DURING THE EVENING THEN FADES IT
OVERNIGHT WITH LOSS OF HEATING AND LACK OF S/SE FLOW THATS BEEN
KEEPING LATE NIGHT BANDING GOING. HOWEVER LOOKS LIKE ENOUGH
INSTABILITY AND STILL VERY MOIST PWATS IN PLACE TO LINGER SOME
CHANCE POPS OVERNIGHT WITH HIGHEST IN THE EVENING MAINLY WEST/SW
CORRIDOR. TRIMMED LOWS DOWN SLIGHTLY BUT MAINLY LOW/MID 60S FOR
NOW.
&&
.SHORT TERM /THURSDAY THROUGH FRIDAY/...
THURSDAY AND THURSDAY NIGHT NIGHT WILL BEGIN A WEATHER TRANSITION
PERIOD WITH AN INCOMING COLD FRONT FROM THE WEST. THE BULK OF THE
HEAVIER SHOWERS WILL EITHER BE WITH THE REMNANT TROPICAL LOW ACROSS
THE OHIO VALLEY...AND/OR OFF THE VA/NC COAST WITH THE COASTAL
LOW...AND/OR ALONG THE GULF WITH A WAVE DEVELOPING ALONG THE
SOUTHERN END OF THE FRONT.
A LINE OF CONVECTION ASSOCIATED WITH THE FRONT WILL TRAVEL
EAST ACROSS OUR AREA DURING THE AFTERNOON AND OVERNIGHT HOURS.
SPS HAS PLACES A SLIGHT RISK TO OUR WEST ACROSS SE KY TO
SRN ALABAMA. ATTM FOR US WITH FRONTAL PASSAGE...THE MAIN THREAT
IS HEAVY RAIN AND LOCALIZE FLOODING. LOOKS LIKE BEST INSTABILITY AND
DYNAMICS WILL BE LOCATED TO OUR WEST.
ON THURSDAY PLAYED TEMPERATURES CLOSE TO MAV GUID. HIGHS WILL VARIED
FROM THE UPPER 70S TO MID 80S. OVERNIGHT LOWS WILL REMAIN MUGGY WITH
READINGS FROM AROUND 60 TO THE UPPER 60S.
A FEW LINGERING SHOWERS ARE POSSIBLE ON FRIDAY AND WILL BE DEPENDANT
ON HOW FAR SOUTH THE BOUNDARY DRIFTS. THE WAVE ALONG THE GULF MAY
SLOW THE FRONTS SOUTHERN PROGRESSION DURING THE DAY FRIDAY. AS A
RESULT...ELECTED TO INCREASE POPS ACROSS SOUTHERN PORTIONS. WENT
WITH ADJMAVBC GUID FOR HIGHS FROM THE MID 70S TO THE MID 80S.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A FEW LINGERING SHOWERS ARE POSSIBLE ON FRIDAY AND WILL BE DEPENDANT
ON HOW FAR SOUTH THE BOUNDARY DRIFTS. THE WAVE ALONG THE GULF WILL
LIKELY SLOW THE FRONTS SOUTHERN PROGRESSION DURING THE DAY FRIDAY.
AS THE WAVE MOVES OFF THE NC COAST...COOLER DRIER CONDITIONS WILL
PREVAILS THROUGH THE WEEKEND. THE CHANCE FOR RAIN WILL INCREASE
MONDAY AFTERNOON ESPECIALLY ALONG THE EASTERN AND SOUTHERN SLOPES OF
THE BLUE RIDGE. THE DEVELOPMENT OF ANY STORMS ON MONDAY WILL DEPEND
ON HOW QUICKLY THE AREA WILL BECOME SATURATED. IF SATURATION IS
GOOD ENOUGH...SCATTERED PULSE STORM ARE LIKELY MONDAY AND TUESDAY
AFTERNOON.
TEMPERATURES THROUGH THE PERIOD WILL BE AROUND NORMAL. HUMIDITY
LEVELS WILL BE SIGNIFICANTLY LOWER THROUGH THIS WEEKEND.
&&
.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
AVIATION CONCERNS SIMILAR TO LAST NIGHT GIVEN SE FLOW AND
SUBSEQUENT LOWER CIGS OVERNIGHT INTO WED MORNING. ATTM...GETTING
SOME NE TO EAST COMPONENT TO THE WIND INTO LYH AND THIS HAS
DROPPED CIGS BELOW 1KFT. ATTM...DO NOT SEE MUCH IMPROVEMENT HERE
UNTIL MID MORNING WED GIVEN THE FRONT NEARBY SO LEFT CIGS AROUND 5
HUNDRED FEET OVERNIGHT. SHOULD SEE THIS OCCUR AT ROA/DAN AS WELL
OVERNIGHT. WILL KEEP SHOWERS IN THE TAFS...BUT COVERAGE OF HEAVIER
SHOWERS WILL BE HARD TO PINPOINT AT THIS TIME. BLF/LWB WILL STAY
MAINLY MVFR OVERNIGHT WITH SOME IFR POSSIBLE AT BLF BEFORE THE
FLOW TURNS TO THE SOUTH TOWARD MORNING.
AS THE FLOW TURNS SOUTH AT ALL SITES BEFORE MIDDAY
WEDNESDAY...CIGS IMPROVE TO MVFR AND THEN VFR BY AFTERNOON.
SHOWERS WILL BE A THREAT ONCE AGAIN ALONG WITH THE ISOLATED TO
SCATTERED THUNDERSTORM. FOR NOW CB HAS BEEN INCLUDED IN THE CLOUD
GROUPS ALONG WITH VICINITY MENTION IN SPOTS.
WE WILL REMAIN IN A WET PATTERN INTO FRIDAY WITH PERIODS OF
INCREASED CHANCES OF SHRA/TSRA. PROLONGED PERIODS OF SUB- VFR
CIGS/VSBYS ARE EXPECTED ESPCLY THRU THURSDAY BEFORE SOME DRYING
DEVELOPS BEHIND A PASSING COLD FRONT FOR THE END OF THE WEEK INTO
SUNDAY.
&&
.HYDROLOGY...
THE PATTERN REMAINS CONDUCIVE TO LOCALIZED HEAVY RAINS IN BANDS
OF SHOWERS/AND OR ISOLATED TSTMS. CONTINUED OVERNIGHT TRAINING OF
SHRA ALONG THE BLUE RIDGE HAS RESULTED IN ANOTHER 1-3 INCHES OF
RAIN IN ISOLATED SPOTS. FFG IS FAIRLY HIGH IN THE PIEDMONT AND
FOOTHILLS OF VA...GENERALLY 2.5 IN 1 HOUR TO 3.5 IN 3 HRS AND
GIVEN LESS COVERAGE OVERNIGHT THERE APPEARS FLOOD THREAT HAS
BECOME LESS. IN NW NC AND ALONG AND WEST OF THE BLUE RIDGE IN SW
VA...WHERE LARGE CLUSTERS OF HEAVY RAIN ARE LESS LIKELY...FFG IS
LOWER BUT THERE IS STILL A THREAT OF SMALLER AREAS WITH HEAVY RAIN
ABOVE FLASH FLOOD GUIDANCE ESPCLY NW NC WHERE BANDS PERSIST..
