DISCUSSION
AS OF 225 PM EST SUNDAY...
KEY MESSAGE 1... COLD WEATHER ADVISORIES ARE IN EFFECT TONIGHT
THROUGH MID MORNING MONDAY OVER MUCH OF NORTHEAST NC AND EASTERN
VA, INCLUDING THE VA EASTERN SHORE. WIND CHILLS AROUND ZERO
TONIGHT WILL LINGER THROUGH MID-MORNING MONDAY. ADDITIONALLY,
SNOW ACROSS THE THE EASTERN TIDEWATER AREA INTO NORTHEAST NC
WILL RESULT IN SLIPPERY ROAD CONDITIONS THROUGH MONDAY MORNING.
~976MB SFC LOW PRESSURE CONTINUES TO DEEPEN WELL OFFSHORE OF
THE MID- ATLANTIC COAST THIS AFTERNOON AS IT MOVES NE AND AWAY
FROM THE COAST. SNOW REPORTS OF 2-5" WERE COMMON ACROSS FAR
SOUTHERN VA INTO SOUTHERN CHESAPEAKE/VB, WITH 5-8 AND LOCALLY AS
HIGH AS 10-12".
WIND HEADLINES HAVE BEEN ALLOWED TO DROP OFF, BUT WIND GUSTS OF
20-30MPH STILL LINGER ALONG THE COAST. EVEN AS WINDS DIMINISH,
ANOTHER COLD NIGHT IS AHEAD TONIGHT. LOWS IN THE LOW TO MID
TEENS ARE FORECAST (AND IN THE SINGLE DIGITS ACROSS NE NC).
COLD WEATHER ADVISORIES HAVE BEEN ISSUED FOR MUCH OF HAMPTON
ROADS AND NE NC, INCLUDING THE VA EASTERN SHORE. HAVE DECIDED
NOT TO EXTEND WINTER WEATHER ADVISORIES FOR BLACK ICE/SLIPPERY
ROAD CONDITIONS WHERE SNOWPACK WILL REMAIN LOCKED IN OVERNIGHT.
HOWEVER, DID ACCOUNT FOR SLIPPERY ROADS IN THE COLD WEATHER
ADVISORY.
KEY MESSAGE 2...A FRONT PASSING THROUGH THE AREA MID WEEK MAY
BRING A PERIOD OF LIGHT RAIN/SNOW TO THE AREA. THE LATEST
GUIDANCE SUGGESTS SNOW ACCUMULATIONS OF AN INCH OR LESS.
REMAINING DRY AND MAINLY CLEAR/SUNNY TOMORROW INTO TUESDAY
MORNING, WITH INCREASING CLOUDS TUESDAY AFTERNOON AND EVENING
AHEAD OF A WEAK SHORTWAVE TROUGH AND ITS ASSOCIATED COLD FRONT
DROPPING THROUGH THE LOCAL AREA. HIGH PRESSURE DROPS OUT OF THE
CANADIAN PRAIRIES MONDAY NIGHT/TUESDAY, AND WILL REMAIN TO OUR
NNW. LOW PRESSURE DEVELOPS OVER THE PLAINS AND LIFTS INTO THE
OHIO VALLEY. THESE SYNOPTIC DETAILS LEND THEMSELVES TO
DEVELOPING W-SW WINDS AND MODERATING TEMPERATURES OVER THE LOCAL
AREA. GIVEN THE MARGINAL TEMPERATURES, THE RELATIVELY WEAK
OVERRUNNING MOISTURE, AND GULF MOISTURE TRANSPORT/FORCING
DISPLACED WELL TO OUR W-NW, IT'S NOT SURPRISING THAT BOTH THE
NBM AND THE GRAND ENSEMBLE IN GENERAL ARE SHOWING MINIMAL WINTRY
IMPACTS FOR OUR AREA AT THIS TIME WITH THIS SYSTEM. SINCE THE
SYSTEM STILL LOOKS A BIT WEAKER, NOT SEEING MUCH EVIDENCE OF A
PROMINENT WARM NOSE YET THAT WOULD MAKE FZRA MORE OF A CONCERN.
THEREFORE, STILL LOOKING LIKE MOST OF THE AREA WOULD SEE
PREDOMINATELY LIGHT RAIN, PERHAPS WITH A FEW SNOWFLAKES AT THE
START, AND SOME LIGHT SNOW POSSIBLE ON THE BACK SIDE OF THE
DEPARTING SYSTEM. ANY MEASURABLE SNOW WOULD LIKELY BE CONFINED
TO THE NORTHERN COUNTIES, BUT CANNOT RULE OUT AN CHANGE OVER TO
SNOW FOR THE REST OF THE AREA DURING THE BRIEF WINDOW AS THE
SYSTEM DEPARTS. 12Z/1 GEPS STILL SHOWING SOME LOW-END
PROBABILITIES OF 1-2" SNOW, WITH THE REMAINING ENSEMBLES COMING
EVEN LESS BULLISH. HAVE MAINTAINED LOW QPF VALUES <0.10" AND
SOME LIGHT SNOW ACCUMULATIONS < 1" FOR WEDNESDAY FOR NOW AND
WILL CONTINUE TO WATCH THE EVOLUTION OF THIS SYSTEM.
KEY MESSAGE 3...AFTER TEMPERATURES BRIEFLY MODERATE FOR THE
MIDWEEK PERIOD, ANOTHER INFLUX OF ARCTIC AIR WILL BRING SHARPLY
COLDER TEMPERATURES LATE THIS WEEK INTO NEXT WEEKEND.
COLD HIGH PRESSURE BUILDS EAST ON THE HEELS OF THE DEPARTING
SYSTEM, USHERING IN ANOTHER COLD AIRMASS FOR THE LATE WEEK
PERIOD INTO NEXT WEEKEND. ANOTHER CLIPPER SYSTEM FRIDAY NIGHT
AND SATURDAY WILL USHER IN A REINFORCING SHOT OF COLDER AIR,
BRINGING ANOTHER VERY COLD (THOUGH MAINLY DRY!) WEEKEND INTO
EARLY NEXT WEEK.
AVIATION /00Z MONDAY THROUGH FRIDAY/
AS OF 615 PM EST SUNDAY...
VFR CONDITIONS PREVAIL THROUGH THE 00Z TAF PERIOD. REMOVED THE
MENTION OF GUSTS AT ALL TERMINALS BUT COULD SEE A FEW GUSTS AT
SBY AND ORF THROUGH THE EVENING HOURS. SOME GUSTS 15-20 KT ARE
POSSIBLE AS MIXING GETS UNDERWAY ON MONDAY. LLWS IS INDICATED
AT RIC AND SBY THROUGH 06Z.
OUTLOOK: VFR CONDITIONS PERSIST THROUGH TUESDAY. INCREASING
CLOUDS TUESDAY MORNING AND AFTERNOON. THERE IS A CHANCE FOR
REDUCED CIGS AND SOME LIGHT RAIN OR SNOW LATER TUE NIGHT THROUGH
WED NIGHT. HOWEVER, CONFIDENCE REMAINS LOW AT THIS TIME.
MARINE
AS OF 230 PM EST SUNDAY...
KEY MESSAGES:
- ALL STORM WARNINGS HAVE BEEN REPLACED WITH GALE WARNINGS AS
OF THIS AFTERNOON.
- LIGHT TO MODERATE FREEZING SPRAY IS POSSIBLE THROUGH THIS EVENING.
- LIGHTER WINDS AND CALMER MARINE CONDITIONS EXPECTED FOR MOST
OF THIS UPCOMING WEEK, THOUGH MARGINAL SCAS ARE POSSIBLE
THURSDAY MORNING.
STRONG (~979 MB) LOW PRESSURE IS CENTERED ABOUT 500 MILES E OF
COASTAL VA THIS AFTERNOON, WITH WINDS TRENDING DOWN AS THE
PRESSURE GRADIENT SLACKENS. STORM WARNINGS HAVE BEEN REPLACED WITH
GALE WARNINGS AS OF THIS AFTERNOON'S UPDATE. HOWEVER, STILL SEEING
OCCASIONAL GUSTS OVER 40 KT IN THE SOUTHERN COASTAL WATERS. SCAS ARE
IN EFFECT FOR THE UPPER RIVERS. THE OVERALL TREND THROUGH THE REST
OF TODAY INTO TONIGHT WILL BE CONTINUED DECREASING WINDS, THOUGH
GUSTS TO 25-30 KT WILL PROBABLY LINGER THROUGH MONDAY MORNING. MUCH
LIGHTER WINDS ARE EXPECTED MONDAY AFTERNOON THROUGH WEDNESDAY AS
HIGH PRESSURE SETTLES SOUTH OF THE REGION. A WEAK AREA OF LOW
PRESSURE AND AN ASSOCIATED COLD FRONT THEN LOOK TO MOVE THROUGH
LATER WEDNESDAY. CAA BEHIND THE FRONT COULD LEAD TO MARGINAL SCA
CONDITIONS (WITH NORTHERLY WINDS) WEDNESDAY NIGHT INTO THURSDAY
MORNING. A STRONG COLD FRONT COULD BRING SCA OR GALE CONDITIONS BY
NEXT WEEKEND.
FREEZING SPRAY REMAINS A CONCERN THROUGH THIS EVENING. HOWEVER, THE
ICE ACCRETION RATE SHOULD FALL INTO THE "LIGHT" OR "MODERATE"
CATEGORY, AS OPPOSED TO THE "HEAVY" SEEN LAST NIGHT. THEREFORE, THE
HEAVY FREEZING SPRAY WARNINGS HAVE BEEN CANCELLED IN LIEU OF
FREEZING SPRAY ADVISORIES. THESE ARE IN EFFECT THROUGH 00Z/7 PM
THIS EVENING. ELEVATED SEAS WILL ALSO TREND DOWNWARD AS WE HEAD INTO
TONIGHT, BUT WILL REMAIN 6-9 FT THROUGH MONDAY MORNING. SUB-5 FT
SEAS RETURN BY MONDAY NIGHT AND GENERALLY PREVAIL THROUGH THE END OF
THE WEEK. A SIMILAR DOWNWARD TREND IS EXPECTED WITH THE WAVES IN THE
CHESAPEAKE BAY.
CLIMATE
WRAP-UP PNS FOR SNOW AND WIND REPORTS HAVE BEEN ISSUED. SEE PNSAKQ.
NORFOLK WILL LIKELY REMAIN BELOW FREEZING ONCE AGAIN TODAY. ASSUMING
IT DOES SO, IT WILL MARK 5 CONSECUTIVE DAYS BELOW FREEZING. THIS
IS THE LONGEST STRETCH SINCE JAN 8-13, 1981 (6 DAYS).
