AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
528 AM EDT MON APR 23 2012
.SYNOPSIS...
A DEEP AREA OF LOW PRESSURE WILL TRACK NORTHWARD FROM THE
MID-ATLANTIC INTO NEW ENGLAND TODAY...ACCOMPANIED BY STRONG...GUSTY
NORTHWEST WINDS...UNSEASONABLY COLD TEMPERATURES...AND A CHANCE OF
ACCUMULATING SNOW ACROSS THE APPALACHIANS. MILDER...YET STILL BELOW
NORMAL AIR...WILL RETURN TO THE REGION BY MID-WEEK AS A SERIES OF
WEAKER DISTURBANCES TRACK ACROSS THE REGION FROM THE
NORTHWEST...POTENTIALLY BRINGING SHOWERS AND THUNDERSTORMS TO THE
REGION DURING THE LATER HALF OF THE WEEK.
&&
.NEAR TERM /UNTIL 8 AM TUESDAY MORNING/...
AS OF 540 AM EDT MONDAY...
THE WELL ADVERTISED EAST COAST LOW/NOREASTER CONTINUES TO BRING THE
EXPECTED WEATHER TO THE REGION. BAROCLINIC LEAF/DEFORMATION ZONE
CONTINUES TO EXPAND SOUTHWARD INTO SE/EC WV...INCLUDING GREENBRIER
COUNTY. 20-30 DBZ ECHOES PERSISTING/EXPANDING ACROSS NW GREENBRIER
COUNTY THIS HOUR. ALTHOUGH NO GROUND TRUTH VERIFICATION FROM THIS
REGION AS OF YET...IT IS A GOOD BET WITH TEMPS AOB 34F THAT WE ARE
GETTING MODERATE TO HEAVY SNOW AND ACCUMULATIONS AS EXPECTED. WARM
GROUND SHOULD LIMIT TRAVEL PROBLEMS...BUT AS ADVERTISED TREES AND
POWER LINES MAY BE AN ISSUE WITH THE WEIGHT OF THE HEAVY WET SNOW.
HAVE SHOWN CATEGORICAL SN TRANSITIONING TO -SHSN BY EARLY AFTERNOON
ACROSS THE WINTER WX ADVISORY AREA. FOR THE REMAINDER OF THE
CWA...-SHSN EXPECTED HIGHER ELEVATIONS OF VA/NC...WITH LITTLE
ACCUMULATION ON THE DOWNSLOPE SIDE. FURTHER EAST ACROSS THE
PIEDMONT...PCPN HAS ENDED AND DO NOT EXPECT ANY MORE THOSE AREAS.
-SHSN ACTIVITY SHOULD BEGIN TO WIND DOWN AFT 00Z...BUT MAY PERSIST
OVERNIGHT ACROSS MAINLY THE UPSLOPE AREAS OF NW GREENBRIER COUNTY.
WILL NOT CHANGE TIMING OF WSW AT THIS TIME. WIND WILL ALSO BE AN
ISSUE TODAY...BUT SPEEDS OF 50+ SEEMED A LITTLE EXCESSIVE AND NOT
QUITE IN LINE WITH NEIGHBORING CWAS. HAVE DROPPED MAX GUSTS DOWN TO
45. HAVE USED 850MB TECHNIQUE FOR MAX TEMPS TODAY AND MODEL BLEND
FOR MIN TEMPS...USED A MODEL BLEND...WHICH RESULTED IN FREEZING
TEMPS ACROSS THE NC MOUNTAINS/SW VA MOUNTAINS AND ALL OF THE WV
COUNTIES. THUS...HAVE ISSUED A FREEZE WARNING FOR THESE AREAS FOR
04Z-13Z TUE. A FREEZE WATCH/FREEZE WARNING MAY ALSO BE NEEDED IN
SOME OF THESE SAME AREAS AND POTENTIALLY EVEN PIEDMONT AREAS WED
MORNING...ALTHOUGH 850MB TEMPS LESS SUPPORTIVE OF SUCH. LIMITING
FACTOR TUE MORNING WILL BE WIND. FROST SHOULD NOT BE AN ISSUE EXCEPT
IN VERY ISOLATED SPOTS.
&&
.SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/
AS OF 330 AM EST MONDAY...
BY TUESDAY MORNING...THE LOW WILL CONTINUE TO PUSH AWAY FROM OUR
AREA...HAVING ENTERED SOUTHERN CANADA. HOWEVER...WILL STILL SEE THE
LOWS INFLUENCE IN THE FORM OF A TIGHT PRESSURE GRADIENT ACROSS THE
REGION...RESULTING IN WIND SPEEDS DURING THE AFTERNOON BETWEEN 15
MPH AND 20 MPH ACROSS THE MOUNTAINS...WITH GUSTS AS HIGH AS 35
MPH...ESPECIALLY ALONG THE RIDGELINES. RAIN WILL ALSO REMAIN IN THE
FORECAST HEADING INTO THE EVENING AS A FRONTAL BOUNDARY WILL
STRETCH FROM THE HIGH PLAINS THROUGH THE NORTH CAROLINA MOUNTAINS...
AND OFF OF THE CAROLINA COAST. WEAK UPPER LEVEL DISTURBANCES WILL
PASS ALONG THIS BOUNDARY TUESDAY EVENING THROUGH LATE WEDNESDAY
EVENING...TRIGGERING SHOWERS MAINLY FOR THE THE NORTH CAROLINA
MOUNTAINS AND THE MOUNTAIN EMPIRE...BUT WILL NOT RULE OUT ANY
RAINFALL ANYWHERE ACROSS THE REGION.
ON THURSDAY MORNING...ANOTHER LOW PRESSURE SYSTEM WILL EXIT OUT OF
THE CENTRAL PLAINS...AND WILL PUSH ACROSS THE GREAT LAKES. BY THIS
TIME...SOUTHERLY WINDS WILL BECOME REESTABLISHED...AS THIS LOW DRAGS
A COLD FRONT TOWARD OUR AREA FROM THE NORTHWEST. WITH WARM MOIST AIR
FILTERING BACK INTO THE AREA...AFTERNOON TEMPERATURES CAN BE
EXPECTED TO CLIMB INTO THE LOW TO MID 70S EAST...AND INTO THE MID
TO UPPER 60S WEST. THE MAIN CONCERN FOR THURSDAY HOWEVER WILL BE
THE POTENTIAL FOR STRONG TO POSSIBLY SEVERE THUNDERSTORM ACTIVITY
DURING THE AFTERNOON AND EVENING AS THE COLD FRONT APPROACHES OUR
AREA. FORECAST MODELS ARE HINTING AT MODERATE ATMOSPHERIC
INSTABILITY DURING THE AFTERNOON AS AN UPPER LEVEL DISTURBANCE
PUSHES ACROSS WEST VIRGINIA. WITH A FEW DAYS TO GO BEFORE THIS
SYSTEM PASSES ACROSS OUR AREA...WILL SIMPLY CONTINUE TO MONITOR
THE DEVELOPMENT OF THIS STORM SYSTEM.
&&
.LONG TERM /FRIDAY THROUGH SUNDAY/...
AS OF 330 AM EST MONDAY...
EXPECT DRIER CONDITIONS FRIDAY INTO FRIDAY NIGHT WITH THE SFC HIGH
MOVING FROM THE GREAT LAKES INTO THE MID ATLANTIC. THE FLOW WILL BE
NORTHEAST AND KEEP IT COOL...ALTHOUGH CLOUD COVER WILL BE LIMITED
WITH DRIER AIR WORKING IN FROM THE NORTH. THIS SETUP COULD POSE SOME
PROBLEMS IN TERMS OF CLOUD COVER IN THE LOW LAYERS...IF MOISTURE CAN
BE TRANSPORTED IN MORE OFF THE ATLANTIC AND GET STUCK IN A NEAR SFC
INVERSION...BUT GIVEN ITS FAR OUT IN THE EXTENDED...WILL EASE OFF ON
THIS SCENARIO.
WITH THE AMPLIFICATION IN THE RIDGE TO THE WEST GOING INTO THE
WEEKEND...THE FRONTAL BOUNDARY SHOULD WORK BACK NEWD TOWARD THE
CENTRAL APPALACHIANS BY THE END OF NEXT WEEKEND. THE MOISTURE SHOULD
INCREASE...BUT MODELS SHOW LIGHT QPF...AND THINKING IS FOR GOING
WITH SLIGHT CHANCE TO LOW CHANCE POPS IN THE WEST SATURDAY WITH SOME
UPPER ENHANCEMENT/WAA MOVING ACROSS...WITH LESS CHANCE INTO SUNDAY
AS THE RIDGE WILL BE PUSHING MORE INTO THE APPALACHIANS...WITH A
QUICK MOVING FRONT SHIFTING SOUTHEAST INTO THE MID ATLANTIC AS
ANOTHER SHORTWAVE DIGS AROUND THE TROUGH OVER THE NORTHEAST.
STILL QUESTIONS IN TERMS OF CLOUD COVER/TEMPS GIVEN SOLUTIONS FROM
THE MODELS BEYOND THURSDAY...SO CONFIDENCE IN THE FORECAST IS LOW AT
THIS TIME. HOWEVER...OVERALL SETUP FAVORS LITTLE CHANCE OF A
SIGNIFICANT RAINFALL.
TEMPS DURING THE PERIOD SHOULD BE SEASONAL.
&&
.AVIATION /09Z MONDAY THROUGH FRIDAY/...
AS OF 145 AM EDT MONDAY...
MUCH OF THE CWA CURRENTLY LOCATED BETWEEN DEPARTING MAIN RAIN SHIELD
FROM COASTAL LOW...ALONG THE DELMARVA...AND DEVELOPING BAROCLINIC
LEAF/DEFORMATION ZONE WV. MVFR CIGS CONFINED MAINLY TO HIGHER
ELEVATIONS OF SW VA AND IFR CIGS CONFINED TO WV COUNTIES. -DZ NOTED
BCB WESTWARD WITH UP EVIDENT AT BLF. EXPECT SOUTHWARD DEVELOPMENT OF
BAROCLINIC LEAF INTO BLF/LWB/BCB THROUGH THE EARLY MORNING
HOURS...WITH PCPN IN THESE AREAS -DZSN CHANGING TO -SHSN AROUND
DAYBREAK. EXPECT -SHSN WITH BKN-OVC MVFR CIGS BLF/LWB/BCB THROUGH
18Z...THEN BEGIN TO TAPER OFF WITH MORE BREAKS IN THE OVC DEVELOPING
AS COASTAL LOW PULLS NE AWAY FROM THE REGION. APPROACHING NW FLOW
SHORT WAVE WILL SPREAD CI ACROSS THE SW HALF OF THE CWA BY 00Z. ROA
WILL LIKELY REMAIN MOSTLY PCPN FREE THROUGH TAF VALID PERIOD WITH
PERIODS OF MVFR CIGS EARLY MORNING THROUGH MID-AFTERNOON IN ANY
-SHRA THAT MAKE IT THAT FAR SE BEFORE DISSIPATING. FOR
LYH-DAN...EXPECT MOSTLY VFR CIGS THROUGH TAF VALID PERIOD WITH NO
MEANINGFUL PCPN. VSBYS MOSTLY VFR...EXCEPT MVFR IN -DZ/-SHSN/-SHRA
LWB-BLF-BCB AT TIMES THROUGH 18Z...MAINLY PRIOR TO 15Z THOUGH. WINDS
WILL BE THE OTHER MAIN ISSUE THROUGH TAF VALID PERIOD...ESPECIALLY
AFTER 13Z WITH NW-WNW WINDS 15-20KTS INCREASING TO 20-25KTS
15Z-18Z...WITH GUSTS RANGING FROM 30KTS LWB TO NEAR 40KTS ROA. WINDS
WILL BE A MAJOR ISSUE FOR ANY GENERAL/COMMERCIAL AVIATION TODAY AT
ALL TAF SITES...BUT MOST NOTABLY ROA/BCB/BLF.
AS OF 645 PM EDT SUNDAY...
UPPER TROF FINALLY LIFTS OUT A BIT TUESDAY ALLOWING WINDS TO
WEAKEN BUT STILL GUSTY WITH IMPROVING CIGS TO MAINLY VFR. FORECAST
REMAINS LOW CONFIDENCE FROM MID WEEK ON WITH POTENTIAL TO SEE
MORE CLUSTERS OF SHRA/TSRA DROP IN FROM THE NW WED INTO THU AS
ANOTHER COLD FRONT SAGS IN FROM THE NORTH. EXACTLY WHERE THE FRONT
ENDS UP IN QUESTION BUT MAY PUSH FAR ENOUGH SOUTH TO BRING VFR
BACK BY THE END OF THE WEEK AT THIS POINT.
