Area forecast discussion, Apr 25, 3:24 PM EDT, 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
324 PM EDT FRI APR 25 2014

.SYNOPSIS...
A COLD FRONT WILL MOVE EAST ACROSS THE REGION THIS EVENING
BRINGING AN END TO THE ONGOING SHOWERS AND STORMS. HIGH PRESSURE
WILL MOVE ACROSS THE MID ATLANTIC AND SOUTHEAST STATES THIS
WEEKEND INTO EARLY NEXT WEEK. A SLOW MOVING COMPLEX STORM SYSTEM
WILL AFFECT THE REGION BY THE MIDDLE OF NEXT WEEK.
&&

.NEAR TERM /THROUGH SATURDAY/...
AS OF 1045 AM EDT FRIDAY...

A NEGATIVELY TILTED SHORTWAVE TROUGH OVER THE OHIO AND TENNESSEE
VALLEYS THIS MORNING WILL SHIFT EASTWARD ACROSS THE APPALACHIANS
DURING THE AFTERNOON BEFORE MOVING OFFSHORE AFTER 00Z/8PM THIS
EVENING. AT THE SURFACE...LOW PRESSURE CENTERED OVER THE WESTERN
OHIO VALLEY WILL LIFT NORTHEAST ALONG THE LOWER GREAT LAKES...AND
A TRAILING COLD FRONT EXTENDING SOUTHWARD FROM THE LOW WILL MOVE
EWD ACROSS THE APPALACHIANS INTO THE VA/NC PIEDMONT BY 00Z/8PM
THIS EVENING. NUMEROUS SHOWERS AND SCATTERED THUNDERSTORMS ARE
EXPECTED TO DEVELOP AHEAD OF THIS FEATURE...WITH SEVERE STORMS
POSSIBLE FROM THE VA/NC PIEDMONT EASTWARD INTO THE TIDEWATER OF
VIRGINIA AND NORTH CAROLINA.

SHOWER AND SCATTERED THUNDERSTORMS WILL SPREAD EAST INTO THE
FOOTHILLS AND PIEDMONT THIS AFTERNOON. UPPER TROUGH IS VIGOROUS
WITH LOTS OF SPIN EVIDENT IN THE WATER VAPOR IMAGERY. 500 MB
TEMPERATURES SHOWED A DECENT COLD POOL AND LAPSE RATES ALREADY
LARGE ENOUGH TO AID IN DYNAMIC LIFT.

CONCERN IS THIS AFTERNOON AS THE EASTERN MID ATLANTIC HEATS UP IN
ADVANCE OF THIS FEATURE...CAPE INCREASING INTO THE 1000-1500 J/KG
RANGE FROM THE PIEDMONT AND POINTS EAST. HIGH SHEAR ENVIRONMENT
WILL EXIST PER 40 KT LOW LEVEL JET AHEAD OF SYSTEM. IN ADDITION
DIRECTIONAL SHEAR WILL ALSO EXIST PER NEGATIVE ORIENTATION OF THE
UPPER TROF AND BACKING LOW LEVEL FLOW. 0-3KM STORM RELATIVE HELICITY
IS AROUND 200 M2/S2. THIS RAISES CONCERN FOR POTENTIAL SUPERCELLS
AS STORMS EVOLVE OVER ERN VA/NC LATER THIS AFTERNOON. ATTM THINK
GREATEST THREAT FOR SVR STORMS WILL BE EAST OF THE HIGHWAY 29
CORRIDOR. HIGHLIGHTED AS SUCH IN THE HAZARDOUS WEATHER OUTLOOK AND
ADDED GUSTY WINDS AND SMALL HAIL POSSIBILITY INTO THE
FORECAST...WITH WINDOW OF THREAT FROM 2-5PM...STORMS MOVING EAST
OF OUR COUNTY WARNING AREA AFTER 5PM.

ENTIRE SYSTEM IS EXPECTED TO MOVE OFFSHORE TONIGHT...PRESSURE
RISES RESULTING IN BREEZY CONDITIONS OVERNIGHT PER 30-45KT 85H
CROSS BARRIER WIND FLOW. TREND WILL BE FOR CLEARING SKIES...BUT
SINCE THIS SYSTEM IS OF PACIFIC ORIGIN...COLD AIR LACKING...
OVERNIGHT LOWS ARE EXPECTED TO REMAIN ABOVE FREEZING.
&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF 230 PM EDT FRIDAY...

WEAK HIGH PRESSURE WILL BEGIN TO BUILD IN FROM THE NORTH SAT
NIGHT AS A RESIDUAL WEAK BOUNDARY WASHES OUT AND SHORTWAVE
RIDGING STARTS TO TAKE CONTROL. MAY SEE A RENEGADE -SHRA ACROSS
THE EXTREME NW SAT EVENING OTRW MAINLY CLEAR OVERNIGHT. OMEGA
BLOCK ALOFT GAINS AMPLITUDE THE REST OF THE WEEKEND INTO EARLY
NEXT WEEK WITH A COMPLICATED SCENARIO GIVEN A WARM FRONT TO THE
SOUTH...HIGH PRESSURE WEDGING DOWN THE MOUNTAINS...AND MOISTURE
INCREASING UNDER THE SHARP RIDGING ALOFT. THIS LOOKS TO MAINLY
PLAY OUT SUNDAY NIGHT INTO MONDAY WITH DRY AIR HOLDING THE LOW
LEVELS DRY UNTIL LATER SUNDAY NIGHT AND ESPCLY MONDAY WHEN
GUIDANCE BRINGS A FAINT MID LEVEL WAVE UP UNDER THE RIDGE ALOFT.
THIS SHOULD ALLOW FOR A GRADUAL INCREASE IN CLOUDS SUNDAY...THEN
BECOMING MOSTLY CLOUDY SUNDAY NIGHT WITH SLOWLY INCREASING ISENT
LIFT AS THE LOW LEVEL FLOW BECOMES MORE EAST/SE. RAIN CHANCES PICK
UP ON MONDAY AS A LOBE OF DEEPER MOISTURE ARRIVES INTO THE
DEVELOPING WEDGE ALTHOUGH COVERAGE LOOKS DISORGANIZED FOR THE MOST
PART. WILL RUN WITH MOSTLY CHANCE POPS ON MONDAY GIVEN ENOUGH
MOISTURE AND VEERING ALOFT FOR SOME LIGHT PRECIP.

TEMPS TO REMAIN MILD INTO SUNDAY NIGHT WITH HIGHS MOSTLY IN THE
70S SUNDAY PROVIDED ENOUGH INSOLATION...THEN COOLER PER ONLY 60S
WITHIN THE WEDGE AREA IN THE CENTRAL/EASTERN SECTIONS AND 70-75
PERIMETER SOUTH AND SW ZONES.
&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 1230 PM EDT FRIDAY...

ACTIVE WEATHER PERIOD IN STORE AS STRONG UPPER LEVEL LOW PRESSURE
DEVELOPS OVER THE CENTRAL STATES AND THEN SPIRALS VERY SLOWLY NE
REACHING THE WESTERN GREAT LAKES BY THE END OF THE WEEK. THIS WILL
KEEP AN INCREASING FLUX OF DEEP MOISTURE INTO THE AREA THROUGH AT
LEAST MID WEEK BEFORE THE TRAILING COLD FRONT FINALLY MOVES OVER AND
TO THE EAST THURSDAY INTO FRIDAY. DEVELOPING WEDGE ACROSS THE REGION
EARLY ON WILL GET DEEPLY ENTRENCHED MONDAY NIGHT AND ESPCLY TUESDAY
AS THE INTIAL SURGE OF LIGHT RAIN CROSSES AND FORMS A WEAK WAVE
ALONG THE COASTAL WARM FRONT. THIS COOL POOL SHOULD KEEP THE
BOUNDARY TO THE SOUTH AND EVENTUALLY ALONG THE APPLACHIANS BEFORE
PERHAPS WARM ADVECTION PUNCHES IT OUT LATER WEDNESDAY AHEAD OF A
FRONT ALOFT PRESSING IN FROM THE WEST. OVERRUNNING IN ADVANCE OF
THIS BOUNDARY LIKELY TO KEEP PERIODS OF RAIN GOING TUE INTO TUE
NIGHT THEN POSSIBLY A MORE ENHANCED BAND OF HEAVIER SHOWERS/STORMS
WED WEST AS THIS FEATURE PUSHES EAST PER GFS/EC BLEND. PENDING LATER
RUNS...THIS COULD BRING SOME WATER ISSUES TO SPOTS DESPITE CURRENT
DRYNESS PER LATEST ENSEMBLE OUTPUT. ALSO BOUNDARY LIFTING NORTH
COULD POSE SOME SEVERE THREAT AS WELL PENDING HOW FAST THE WEDGE
LIFTS OUT BY WED EVENING. OTRW BUMPING POPS FROM CHANCE MONDAY
NIGHT TO LIKELYS TUE AND CATEGORICAL INTO WED AFTERNOON.

ACTUAL SURFACE FRONT LOOKS TO FINALLY CROSS THE MOUNTAINS THU BUT
LACKING MOISTURE BY THEN SO KEEPING SOME CHANCE POPS. SHOULD DRY OUT
FURTHER IN THE WAKE OF THE FRONT ON FRIDAY WITH ANY ISOLATED SHRA
CONFINED MOSTLY TO THE UPSLOPE AREAS OF THE FAR NW AT BEST.

TEMPS WILL BE TRICKY UNDER THE WEDGE WITH POTENTIAL FOR A VERY COOL
DAY ON TUE AND MUCH OF WED BEFORE SEEING READINGS SURGE FROM SOUTH
TO NORTH LATE WED AFTERNOON. THUS PLAN TO STAY WELL BELOW MOS/HPC
ESPCLY ON TUE AND ACROSS THE NORTH WED. SHOULD RETURN TO NORMAL OR
ABOVE HIGHS THU THEN COOLER POST FRONTAL FRI WITH MOST IN THE 60S
TO LOW 70S PIEDMONT.
&&

.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
AS OF 130 PM EDT FRIDAY...

SHOWERS AND THUNDERSTORMS WILL TO INCREASE IN COVERAGE AHEAD OF
AN APPROACHING COLD FRONT. WIDESPREAD MVFR CEILINGS CAN BE
EXPECTED TODAY WITH SCATTERED TO NUMEROUS SHOWERS AND EMBEDDED
THUNDERSTORMS CONTINUING THROUGH 22Z/6PM. ISOLATED IFR CONDITIONS
ARE ALSO POSSIBLE IN THE HEAVIER STORMS. THE SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO CLEAR THE AREA BY 22Z/6PM WITH A
RETURN TO VFR CONDITIONS THIS EVENING...AND SATURDAY. BEHIND THE
FRONT...FOR ABOUT A 24 HOUR PERIOD...WINDS WILL BE GUSTY OUT OF
THE NORTHWEST...DIMINISHING BY SUNSET SATURDAY.

EXTENDED AVIATION DISCUSSION...

VFR CONDITIONS SHOULD PREVAIL BOTH SATURDAY AND SUNDAY.
CLOUD COVER WILL STEADILY INCREASE BY MONDAY...AS A LOW PRESSURE
SYSTEM SLOWLY ARRIVES FROM THE WEST. CONDITIONS MAY DROP BELOW VFR
WHEN SCATTERED SHOWERS MOVE OVER THE MID ATLANTIC DURING LATE
MONDAY...AND CHANCES FOR MVFR ARE EVEN BETTER ON TUESDAY DUE TO
PROLONGED CLOUDS AND RAIN.
