AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
758 PM EDT SUN MAY 3 2009

.SYNOPSIS...
A STATIONARY FRONT OVER THE AREA WILL BE THE FOCUS FOR SHOWERS AND
THUNDERSTORMS TONIGHT AND MONDAY. A STRONG UPPER LEVEL DISTURBANCE
WILL MOVE ALONG THE FRONT EARLY MONDAY...RESULTING IN AREAS OF
MODERATE TO HEAVY RAIN.

&&

.NEAR TERM /THROUGH MONDAY/...
LIGHT SPORADIC SHOWERS WILL CONTINUE TO FALL ACROSS MOST OF THE AREA
THIS AFTERNOON AND EVENING...ALONG AND WEST OF THE BLUE RIDGE.
ACROSS THE NW NC FOOTHILLS/PIEDMONT AND INTO SOUTHSIDE
VA...INSTABILITIES HAVE COME UP THIS AFTERNOON WITH LESS CLOUD COVER
AND SCATTERED SHOWERS/ISOLATED THUNDERSTORMS WILL BE POSSIBLE
THROUGH THE EARLY EVENING. NOT EXPECTING ANY SEVERE WEATHER BUT
MODERATE TO LOCALIZE HEAVY RAIN IS POSSIBLE.

THROUGH THE EVENING...SHOWER COVERAGE WILL DIMINISH SOME BUT NOT
COMPLETELY WITH SOME EASTERN SLOPES HAVING DRIZZLE. WIDE SPREAD RAIN
SHOWERS WILL RE-ENTER THE AREA AFTER MIDNIGHT AS A COMPLEX LOW
PRESSURE SYSTEM TRACKS ALONG THE FRONT FROM THE TENNESSEE VALLEY AND
OVER THE AREA MONDAY MORNING. HEAVY RAINFALL CAN BE EXPECTED ACROSS
THE AREA...ESPECIALLY THE MOUNTAINS. ONE FLY IN THE OINTMENT THAT COULD
REDUCE SIGNIFICANT RAINFALL AMOUNTS AND ANY FLOOD THREAT IS THE
CONVECTION FIRING IN THE SOUTHERN MISSISSIPPI VALLEY THIS AFTERNOON.
IF THIS COMPLEX REMAINS ACTIVE AND STAYS ALONG THE GULF COAST
OVERNIGHT...QPF AMOUNTS MAY BE TO HIGH. HPC HAS SE WV/EXTREME SW VA
IN A SLIGHT RISK FOR EXCESSIVE RAINFALL WITH OVER 2 INCHES OF RAIN
POSSIBLE FROM THIS EVENING UNTIL MONDAY AFTERNOON. WITH CONVECTION
DOWN SOUTH...CURRENT FORECAST ONLY HAS ABOUT AN INCH. ABOUT A HALF
OF AN INCH (LOCALIZED 1.25 INCHES) OF RAIN HAS FALLEN ACROSS THE
MOUNTAINS IN THE PAST 24 HOURS. WITH SPORADIC SHOWERS TODAY...MOST
RAINFALL HAS DRIED UP OR CONSUMED BY SPRING VEGETATION. THEREFORE WILL
HOLD OFF AND ANY FLOOD WATCHES IN THE WEST AND WILL HIGHLIGHT IN
HWO.

ATMOSPHERE IS SATURATED WITH DEEP MOIST SOUTHWEST FLOW...DEW POINTS
HAVE BEEN COMING UP ALL DAY. I DO NOT FORESEE DYNAMICALLY COOLING
FROM RAIN OVERNIGHT AND THEREFORE WENT A CATEGORY ABOVE GUIDANCE ON
OVERNIGHT LOWS AND DEW POINTS...ESPECIALLY IN THE EAST. DEPENDING ON
HOW QUICKLY THE RAIN EXITS TOMORROW...TEMPERATURES WILL LIKELY BE
ABOUT 5 DEGREES BELOW NORMAL.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
ON TUESDAY THE REMNANTS OF THE STATIONARY FRONT MAY STILL BE IN THE
SOUTHERN COUNTY WARNING AREA. THIS WOULD KEEP HIGHS IN THE 50S AND
60S ON THE NORTH SIDE OF THE FRONT. MAIN PLAN WAS TO LOWER TEMPS MON
NIGHT THROUGH TUESDAY NIGHT. LOOKS LIKE THERE MIGHT BE ENOUGH OF A
WEDGE ESPECIALLY ON TUESDAY NORTH OF THE FRONT FOR CENTRAL AND NRN
VA/SE WV TO BE SOCKED IN WITH STRATUS AND FOG...NOT MUCH CHC OF
MEASURABLE PRECIPITATION AND LOTS OF FOG WITH THE LIGHT LOW LEVEL
WINDS MONDAY NIGHT AND TUESDAY.

SHORT WAVE TROF AXIS EVENTUALLY MOVES EAST OF THE FORECAST AREA ON
TUESDAY NIGHT. THIS ALLOWS 500 MB HEIGHTS AND 850 MB TEMPERATURES TO
BEGIN RISING.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
BY WEDNESDAY THE FRONT HAS WASHED OUT AND ANY SURFACE WEDGING IS
GONE...SO WILL STAY WITH WARMER MAXIMUM TEMPERATURES.

ZONAL PATTERN TO BEGIN THIS TIME FRAME THAT GRADUALLY TRANSITIONS TO
MORE RIDGING IN THE SOUTHWEST UNITED STATES AND A BROAD TROF IN THE
NORTHEAST. MODELS HAVE BEEN CONSISTENT BRINGING A SHORT WAVE AND
ASSOCIATED COLD FRONT THROUGH THE MID ATLANTIC REGION SO HAVE KEPT
THE HIGHEST PROBABILITY OF RAIN ON WEDNESDAY NIGHT AND THURSDAY.
TEMPERATURES WILL BE NEAR NORMAL WITH NO MAJOR DEVIATION FROM
GUIDANCE NECESSARY AT THIS TIME.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
A QUASI STATIONARY FRONT CONTINUES TO WAVER NORTH AND SOUTH ACROSS THE
REGION. THIS WILL CONTINUE TO BRING PERIODS MVFR TO IFR CIGS/VSBYS
IN SHOWERS AND LOW CLOUDS...WITH THE IFR CONDITIONS PRIMARILY
NORTH OF THE FRONT AT ROA...LYH AND LWB. A STRONG LOW PRESSURE
WILL MOVE ALONG THE FRONT AND ACROSS THE REGION MONDAY. THIS WILL
BRING A LARGE AREA OF MODERATE TO HEAVY RAIN OVER THE CENTRAL
APPALACHIANS THROUGH EARLY AFTERNOON. AS THE LOW PRESSURE MOVES
EAST OF THE AREA MONDAY AFTERNOON...WEST WINDS BEHIND IT WILL
BRING A BRIEF PERIOD WITH HIGHER CIGS/VSBYS BY LATE MONDAY
AFTERNOON.

MONDAY NIGHT...LOW LEVEL NORTHEAST FLOW WILL PUSH THE FRONT INTO
NORTH CAROLINA...AND THERE IS A GOOD CHC OF MORE IFR CONDITIONS
DEVELOPING. THESE LOWER CIGS/VSBYS WILL SLOWLY LIFT ON TUESDAY AS
THE FRONT GRADUALLY WASHES OUT.

TUESDAY NIGHT THROUGH FRIDAY...THE WEATHER PATTERN REMAINS
UNSETTLED WITH ANOTHER FRONT ARRIVING AND SLOWING DOWN OVER THE
AREA BY WEDNESDAY NIGHT. THIS WILL KEEP SHOWERS AND POSSIBLY TSTMS
AROUND THROUGH THE PERIOD. PERIODS OF MVFR ARE LIKELY...AND IFR IS
POSSIBLE...IN THE VCNTY OF ANY SHOWER OR STORM.

&&

.RNK WATCHES/WARNINGS/ADVISORIES...
