High Wind in Virginia, March 12 to 13, 2014

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
725 PM EDT WED MAR 12 2014

.SYNOPSIS...
A VERY STRONG LOW PRESSURE CENTER AND ITS ASSOCIATED COLD FRONT WILL
PASS THROUGH THE MID-ATLANTIC STATES BY THIS EVENING. AN UPPER LEVEL
TROUGH WILL MOVE ACROSS THE AREA TONIGHT...THEN CANADIAN HIGH
PRESSURE WILL BUILD THROUGH THURSDAY NIGHT AND MOVE OFF THE COAST
FRIDAY. ANOTHER WEAK DISTURBANCE MOVES THROUGH TO START THE WEEKEND.
FOR THE SECOND HALF OF THE WEEKEND...HIGH PRESSURE WILL BUILD OVER
THE GREAT LAKES WHILE ANOTHER UPPER DISTURBANCE PASSES THROUGH THE
MID-ATLANTIC.

&&

.NEAR TERM /THROUGH THURSDAY/...
MUCH OF THE SEVERE THUNDERSTORM WATCH WAS CANCELLED WITH THE COLD
FRONT ALREADY PASSING THRU.

A STRONG PRESSURE SURGE BEHIND THE FRONT HAS BEEN ACCOMPANIED BY
WIDESPREAD WIND GUSTS OF GREATER THAN 45 MPH SO FAR. SEVERAL OBS
HAVE BEEN ON THE HIGH END OF WIND ADVISORY...THOUGH ONE PK WND
GUST REACHED HIGH WIND WARNING CRITERIA...MRB OF 61 MPH.

PREVIOUS DISCUSSION...
SEVERE THUNDERSTORM WATCH #28 HAS BEEN ISSUED FOR COUNTIES EAST OF
THE BLUE RIDGE EXCLUDING THE CENTRAL FOOTHILLS...WHERE THE NARROW
LINE OF CONVECTION ALONG THE FRONT HAS ALREADY PASSED THRU. PER
LATEST RADAR TRENDS AND HRRR SIM REFLECTIVITY FORECAST...EXPECT
THIS LINE TO INTENSIFY A BIT OVER THE NEXT COUPLE OF HRS AS IT
REACHES THE I-95 CORRIDOR AND CHESAPEAKE BAY. THE LINE SHOULD
CLEAR THE CHSPK BAY BETWEEN 730 PM AND 830 PM.

983/984 MB SFC LOW IS NOW IN SRN PA AND THIN CONVECTIVE LINE HAS
EVOLVED FROM THAT LOW SWD ACROSS WV...FAR SWRN VA...AND ERN TN.
CLOUDS ARE TRYING TO BREAK AHEAD OF THIS LINE BUT ARE HAVING
TROUBLE AT THE MOMENT NORTH OF THE VA/NC BORDER. EVEN WITH THE
CLOUD COVER...TEMPS AND DEWPOINTS HAVE SURGED...WITH TEMPS IN THE
MID/UPPER 60S AND DEWPOINTS IN THE 50S SOUTH OF THE FRONT. AN
EARLIER WIND SURGE LED TO 40-50 KNOT GUSTS IN LOUDOUN AND
MONTGOMERY COUNTIES...BUT THIS APPEARS TO HAVE SINCE SUBSIDED. THE
FRONT WILL PASS THROUGH THIS EVENING...USHERING IN MARKEDLY COLDER
AIR.

LETS GO THREAT BY THREAT. FIRST...THE STORM THREAT FOR THIS
AFTERNOON. THE LINE WILL CROSS THE CWA BETWEEN 3 PM AND 8 PM. SO FAR
THERE HAS BEEN LITTLE LIGHTNING IN THIS ACTIVITY AND WIND GUSTS HAVE
NOT REALLY BEEN ANY MORE SIGNIFICANT THAN THE GRADIENT WIND.
REGARDLESS...THIS ACTIVITY IS MOVING INTO A SLIGHTLY WARMER
ENVIRONMENT AS IT GETS HERE...SO IT WILL HAVE TO BE MONITORED. AND
AS WE HAVE SEEN...THE WINDS ARE STRONG ENOUGH ALREADY AS IT IS.

NEXT IS THE WIND THREAT. A WIND ADVISORY STARTS AT 6 PM AND HAS BEEN
EXPANDED TO INCLUDE THE ENTIRE FORECAST AREA. WINDS ARE ALREADY
WIDESPREAD GUSTING TO 25 TO 35 KNOTS AND THIS WILL PICK UP EVEN
FURTHER SINCE THE PRESSURE GRADIENT IS ACTUALLY STRONGER BEHIND THE
FRONT. SOME OF THE GUIDANCE INDICATES WIND GUSTS EXCEEDING 50 KNOTS
THIS EVENING...ESPECIALLY AT HIGHER ELEVATIONS. THEREFORE...THE
POTENTIAL FOR A SHORT-LEAD-TIME UPGRADE TO HIGH WIND WARNING DOES
EXIST BEHIND THE FRONT. WINDS WILL STAY QUITE GUSTY THROUGH THE
MORNING HOURS ON THURSDAY AND THEN VERY GRADUALLY SUBSIDE DURING THE
AFTERNOON.

SHARPLY COLDER TEMPERATURES AND WIND CHILLS ARE ANOTHER THREAT.
TEMPS SHOULD DROP 30-40 DEGREES IN ABOUT FOUR HOURS AS THE FRONT
PASSES...WITH LOWS TONIGHT RANGING FROM THE SINGLE DIGITS IN THE
HIGHLANDS...TO 20-25 EAST OF THE BLUE RIDGE. BETWEEN A LACK OF
RAIN...AND PLENTY OF WIND...THERE PROBABLY WILL NOT BE MUCH IN THE
WAY OF ICING PROBLEMS FOR THE MORNING COMMUTE. WIND CHILLS WILL BE
NO HIGHER THAN THE SINGLE DIGITS AREAWIDE...AND BELOW ZERO IN MANY
LOCATIONS IN THE HIGHLANDS AND NORTHERN MARYLAND. WIND CHILLS COULD
APPROACH 20 BELOW ZERO IN SPOTS IN THE HIGHLANDS. TEMPERATURES WILL
REMAIN NEAR OR BELOW FREEZING IN MOST AREAS ON THURSDAY.

UPSLOPE SNOW WILL DEVELOP WEST OF THE ALLEGHENY FRONT THIS EVENING
AND CONTINUE THROUGH MUCH OF THE NIGHT. CURRENT THINKING IS MAYBE A
COUPLE OF INCHES OF SNOW...BUT THAT AMOUNT COULD VARY GREATLY
DEPENDING ON THE LENGTH OF TIME SNOW OCCURS AND HOW QUICKLY TEMPS
FALL BELOW FREEZING BEHIND THE FRONT. A WINTER WEATHER ADVISORY
CANNOT BE RULED OUT FOR THESE AREAS. ELSEWHERE...SNOW CHANCES APPEAR
SMALL...IF ANY.

FOR DETAILS ON THE MARINE/COASTAL FLOOD/FIRE WEATHER THREATS...SEE
THEIR RESPECTIVE SECTIONS OF THIS DISCUSSION.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY/...
WINDS WILL DIMINISH THURSDAY EVENING AS HIGH PRESSURE MOVES
OVERHEAD. THE LIGHTER WINDS AND A MOSTLY CLEAR SKY SHOULD ALLOW
TEMPERATURES TO PLUMMET THURSDAY EVENING...WITH OVERNIGHT LOWS
GENERALLY AROUND 20 EXPECTED...EXCEPT 20 TO 25 IN THE INNER CITIES.

MILDER WEATHER IS EXPECTED FRIDAY AS COLD HIGH PRESSURE DEPARTS TO
THE EAST AND SOUTHERLY RETURN FLOW SETS UP. HIGHS IN THE 50S TO NEAR
60 ARE EXPECTED.

A COLD FRONT WILL APPROACH THE AREA FROM THE GREAT LAKES FRIDAY
NIGHT INTO SATURDAY...BUT AT THIS TIME DOES NOT APPEAR TO HAVE MUCH
MOISTURE WITH IT. THE BEST CHANCE OF PRECIPITATION WILL BE OVER THE
POTOMAC HIGHLANDS WHERE A FEW RAIN OR SNOW SHOWERS ARE POSSIBLE.
COLDER AIR LAGS BEHIND THE FRONT...SO SATURDAY SHOULD BE ANOTHER
MILD DAY WITH HIGH TEMPERATURES SIMILAR TO THAT OBSERVED ON FRIDAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
SUNDAY WILL LIKELY BE THE NICEST DAY OF THE LONG TERM PERIOD WITH
HIGH TEMPS NEAR 50 DEGREES...NEAR NORMAL FOR THIS TIME OF YEAR...AND
PARTLY SUNNY SKIES. HIGH PRESSURE OVER THE GREAT LAKES WILL KEEP
LIGHT WINDS OUT OF THE NORTH DURING THE DAY. THE FRONTAL BOUNDARY
THAT CROSSED OUR AREA SATURDAY WILL STALL OFF OF THE EAST COAST
SUNDAY NIGHT AND MODAL AGREEMENT IS VERY LOW ON WHAT WILL HAPPEN
NEXT.

UPPER LEVEL TROUGHING OVER THE GREAT LAKES SHOULD ENCOURAGE THE
FORMATION OF A LOW PRESSURE WAVE ALONG THE STALLED BOUNDARY OVER THE
GULF COAST. THIS WAVE SHOULD MOVE UP THE EAST COAST AS THE UPPER
LEVEL TROUGH LIFTS THROUGH THE BEGINNING OF THE WORKWEEK. TRACK AND
TIMING OF THIS COASTAL LOW IS STILL VERY UNCERTAIN...AS THERE IS
VERY HIGH VARIABILITY WITHIN ENSEMBLE MEMBERS OF GLOBAL MODELS.
TRACK WILL PLAY A LARGE ROLL IN PTYPE AND LOCAL IMPACTS. ASSUMING
THAT LOW TRACKS UP THE COAST AND WE REMAIN IN THE COLD SECTOR OF THE
STORM...WINTRY PRECIP IS A REALISTIC EXPECTATION. HAVE FORECAST
HIGHS NEAR 40 AND LOWS IN THE UPPER 20S FOR NEXT WEEK WITH LOW END
CHANCE POPS THROUGH THE ENTIRE BEGINNING OF THE WORKWEEK. HAVE
STARTED PTYPE AS RAIN AND INCLUDED POSSIBILITY OF SNOW OVERNIGHT
MONDAY TO ACCOUNT FOR UNCERTAINTY OF LOW TRACK AND DYNAMICS.

&&

.AVIATION /23Z WEDNESDAY THROUGH MONDAY/...
THIN LINE OF SHRA/POSSIBLE TSRA WILL MOVE THROUGH THE TERMINALS
BETWEEN 20 UTC AND 23 UTC. RELATIVELY BRIEF VSBY/CIG RESTRICTIONS
ARE LIKELY AS THIS LINE PASSES. BIG STORY FOR AVIATION WILL BE THE
GUSTY AND PERSISTENT WIND. WINDS OUT OF THE SOUTH WILL SHIFT OUT OF
THE WEST AND THEN NORTHWEST AS THE FRONT PASSES...AND LIKELY BECOME
EVEN GUSTIER THAN THEY HAVE BEEN. WIND GUSTS OVER 40 KTS ARE LIKELY
AT TIMES. WINDS WILL GRADUALLY SUBSIDE ON THURSDAY. ASIDE FROM THE
CONVECTIVE LINE...VFR CIGS/VSBYS ARE EXPECTED.

VFR CONDITIONS ARE EXPECTED THURSDAY NIGHT THROUGH SATURDAY...WITH
THE EXCEPTION OF TERMINALS OVER THE POTOMAC HIGHLANDS WHERE SUB-VFR
CONDITIONS ARE POSSIBLE IN RAIN OR SNOW SHOWERS. GUSTY NORTHWEST
WINDS OF 15 TO 20 KNOTS WITH GUSTS TO 25 KNOTS ARE EXPECTED THURSDAY
EVENING...BECOMING LIGHT AND VARIABLE AFTER MIDNIGHT. SOUTHERLY
WINDS AROUND 10 KNOTS ARE EXPECTED FRIDAY INTO FRIDAY NIGHT WITH
GUSTS TO 20 KNOTS POSSIBLE. WINDS THEN BECOME WEST AROUND 10 KNOTS
SATURDAY.

&&

.MARINE...
EXPANDED THE GALE WARNING TO ALL WATERS...STARTING EARLIER AND
ENDING LATER. GUSTS OVER 30 KNOTS ARE ALREADY HAPPENING AND WILL
CONTINUE AND EVEN INTENSIFY AS THE FRONT PASSES. GALE-LEVEL GUSTS
WILL CONTINUE THROUGH MOST OF THURSDAY...ESPECIALLY OVER THE MORE
OPEN WATERS OF THE LOWER TIDAL POTOMAC AND MARYLAND CHESAPEAKE BAY.

WINDS WILL GRADUALLY SUBSIDE DURING THE LATE AFTERNOON THURSDAY.

SCA CONDITIONS ARE EXPECTED THURSDAY EVENING IN A GUSTY NORTHWEST
FLOW. A BRIEF LULL IN WINDS IS FORECAST THROUGH FRIDAY
MORNING...WITH GUSTY SOUTHERLY FLOW BRINGING ANOTHER ROUND OF SCA
WINDS FRIDAY AFTERNOON AND EVENING...BEFORE WINDS SLACKEN OFF
OVERNIGHT FRIDAY NIGHT INTO SATURDAY MORNING.

A SMALL CRAFT ADVISORY MAY BE NECESSARY BEGINNING SUNDAY NIGHT AS
A COASTAL LOW MAY MOVE NEAR THE AREA.

&&

.FIRE WEATHER...
ABUNDANTLY DRY AIR WILL ACCOMPANY THE ARCTIC AIRMASS INVADING THE
AREA ON THURSDAY...WITH DEW POINTS BELOW ZERO EXPECTED. THIS WILL
RESULT IN RELATIVE HUMIDITY VALUES BOTTOMING OUT AT 20 TO 25 PERCENT
THURSDAY AFTERNOON...ESPECIALLY EAST OF THE BLUE RIDGE. THE DRY AND
WINDY CONDITIONS MAY RESULT IN AN ENHANCED FIRE SPREAD POTENTIAL. A
FIRE WEATHER WATCH HAS BEEN ISSUED FOR ALL OUR VIRGINIA COUNTIES
EAST OF THE BLUE RIDGE IN COORDINATION WITH NEIGHBORING OFFICES AND
FIRE OFFICIALS. THE REMAINDER OF THE AREA WILL BE FURTHER CONSIDERED
FOR SPS AND POTENTIAL FIRE WEATHER HEADLINES TONIGHT OR TOMORROW.

&&

.TIDES/COASTAL FLOODING...
COASTAL FLOOD ADVISORY HAS EXPIRED. WITH THE ANNAPOLIS BUOY
REMAINING JUST BELOW THRESHOLD DURING THE AFTN HIGH TIDE... COASTAL
FLOODING ELSEWHERE UNLIKELY.

WATER LEVELS WILL SHARPLY DECREASE FOLLOWING FRONTAL PASSAGE...AND
A NEGATIVE ANOMALY OVER ONE FOOT IS LIKELY BY THURSDAY AFTERNOON.
