AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
320 PM EDT SAT AUG 30 2008

.SYNOPSIS...
A WEAK COLD FRONT WILL MOVE SLOWLY THROUGH THE AREA TONIGHT. BY
SUNDAY NIGHT...STRONG HIGH PRESSURE WILL BE BUILDING DOWN THE EAST
COAST BRINGING DRIER AND COOLER AIR INTO THE REGION MONDAY AND
TUESDAY.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
SCATTERED SHOWERS MAY CONTINUE INTO THE EVENING AS FRONTAL BOUNDARY
SLIPS ACROSS THE REGION. WITH HIGH PWATS IN PLACE AND SLOW-MOVING
STORMS MAY SEE SOME HEAVY RAIN AMOUNTS AND LOCALIZED FLOOD PROBLEMS
IN SOME STORMS. FOG/LOW STRATUS A DECENT LIKELIHOOD ESPECIALLY IN
RIVER VALLEYS AND AREAS WHERE PRECIPITATION OCCURS.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
SURFACE HIGH AND UPPER-LEVEL RIDGE BUILDING OVER THE EASTERN US
DURING THE DAY WILL LESSEN THE COVERAGE OF SHOWERS ACROSS THE CWA ON
SUNDAY BUT STILL SOME WIDELY SCATTERED SHOWER ACTIVITY POSSIBLE AS
LOW-LEVEL MOISTURE IS SLOW TO SCOUR OUT AND DECENT INSTABILITY
DEVELOPS UNDER STRONG SUN...ESPECIALLY OVER THE SOUTHERN HALF OF THE
CWA. NOT MUCH CHANGE IN TEMPS AS THICKNESSES ARE LOWER ONLY SLIGHTLY
LOWER WITH HIGHS WITHIN A FEW DEGREES OF CLIMO. KEPT THE LOW POPS IN
THE SOUTHERN PORTION OF FA AND PLAYED LOW TEMPERATURES CLOSE TO
MET GUD.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
A WEDGE DEVELOPS ON MONDAY...BUT MODELS ARE RATHER DRY WITH IT.
HOWEVER...BOTH THE NAM/GFS ARE PRINTING OUT A LITTLE QPF EARLY
MONDAY IN THE SOUTH...IF THIS VERIFIES IT WILL BE CLOUDY AND COOLER
ESPECIALLY ALONG THE SOUTHERN BLUE RIDGE. ADDED SOME LIGHT POPS
ACROSS THE SOUTH. MODELS TYPICALLY DO A POOR JOB WITH SUCH A THIN
LAYER OF HIGHER RH CLOSE TO THE GROUND THIS FAR OUT...ESPECIALLY
WITH A FEW DISTURBANCES ARRIVING OFF THE COASTAL PLAIN. H85
ADJUSTMENT WITH +14C AND A GOOD EAST WIND SUGGEST COOLER MOS
NUMBERS ARE BEST.

ALL MODELS DEVELOP A STRONG MID LEVEL RIDGING OVER ERN CONUS
TUESDAY AND WEDNESDAY WITH ITS AXIS SHIFTING EASTWARD OVER THE MID
ATLC REGION. WHILE THE OVERALL PATTERN IS SIMILAR THERE ARE ENOUGH
DETAIL DIFFERENCES TO IMPACT THE TRACKS OF TROPICAL SYSTEMS GUSTAV
AND HANNA MAINLY MID AND LATE PERIOD. REFER TO LATEST NHC ADVISORIES
FOR DETAIL INFORMATION.

HPC 7 DAY COORDINATES IS SLOWER THAN BOTH THE EC AND GFS...GIVEN
THE LARGE SPREAD AND UNCERTAINTY...HOLDS HANNA OVER FLORIDA...WELL
SOUTH OF THE AREA. INCREASED CLOUD COVER AND ADDED SOME CHCY POPS
BOTH FRIDAY AND SATURDAY GIVEN EASTERLY FLOW OFF THE ATLANTIC.

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
WEAK COLD FRONT CURRENTLY ANALYZED FROM CENTRAL PA SW ACROSS WV
INTO FAR SW VA WILL MAKE VERY SLOW EASTWARD PROGRESS THIS
AFTERNOON. BEST CHANCE FOR SHOWERS/TSTMS WILL BE IN THE LWB
AREA...SCATTERED CONVECTION POSSIBLE ACROSS THE CWA...BUT NOT HIGH
ENUF POPS TO WARRANT INCLUSION IN THE TAFS. IF STORMS DO
DEVELOP...THEY WILL BE SLOW MOVERS AND COULD CAUSE RESTRICTIONS AS
LOW AS IFR.

OVERNIGHT...FAVORABLE CONDITIONS AGAIN FOR FOG/STRATUS DEVELOPMENT
AS DRIER AIR BEHIND THE FRONT DOES NOT MOVE IN UNTIL LATER SUNDAY.
FOG FORMATION WILL DEPEND THE MOST ON SKY COVER.

ANY FOG/STRATUS THAT DEVELOPS MAY HANG IN LONGER ON SUNDAY AS
THERE WILL BE A LIGHT NORTHEAST TO EASTERLY FLOW DURING THE DAY.
BY SUNDAY AFTERNOON...THERE MAY BE ENOUGH HEATING FOR SCATTERED
SHOWERS/TSTMS- BEST CHANCE WILL BE FROM ROA SOUTHWEST ALONG THE
BLUE RIDGE. SUNDAY NIGHT THE FLOW BECOMES MORE EAST TO
SOUTHEAST...AND WITH A MOIST BOUNDARY LAYER...EXPECT LOW CLOUDS
AND FOG TO AGAIN DEVELOP ALONG AND EAST OF THE BLUE RIDGE. THIS
WILL LIKELY AFFECT ROA...LYH AND POSSIBLY DAN. AFTER SUNDAY
NIGHT...WITH THE EXCEPTION OF MOUNTAIN VALLEY FOG DURING THE
OVERNIGHTS...VFR CONDITIONS WILL PREVAIL MONDAY AND INTO THE
MIDDLE OF NEXT WEEK...HIGH PRESSURE BUILDING ACROSS THE MID
ATLANTIC REGION.

&&

.RNK WATCHES/WARNINGS/ADVISORIES...
