DISCUSSION
AS OF 238 AM EST SUNDAY...
KEY MESSAGE 1...REMAINING MILD AND MOSTLY DRY TODAY. HOWEVER, TEMPERATURES
ARE LIKELY TO ABRUPTLY FALL INTO THE 40S AND 50S SUNDAY
AFTERNOON ALONG THE COAST OF EASTERN VIRGINIA AND THE LOWER
EASTERN SHORE.
A STRONG HIGH IS SITUATED OVER THE NORTHERN PLAINS, A WEAKER HIGH
PLANTED ACROSS THE SOUTHEAST, AND A COASTAL TROUGH NOW WELL
OFFSHORE. THE PRESSURE GRADIENT IS NEGLIGIBLE BETWEEN THESE
FEATURES, AND LIGHT WINDS AND GENERALLY CLEAR SKIES ARE PREVAILING.
A FEW LAND-BASED OBS ARE REPORTING PATCHY FOG, WITH ANY DENSER FOG
BEING OBSERVED MAINLY ACROSS NE NC AND OUR SOUTHERN PIEDMONT
COUNTIES. TEMPERATURES RANGE FROM THE UPPER 30S TO LOWER 40S, WHICH
IS RIGHT AROUND TO JUST ABOVE NORMAL FOR THIS TIME OF YEAR.
TODAY WILL FEATURE SOUTHWEST FLOW AHEAD AND ANOTHER CHANCE FOR MORE
"SPRING-LIKE" TEMPERATURES AS WE START METEOROLOGICAL SPRING AHEAD
OF AN APPROACHING BACKDOOR COLD FRONT. AS THE FRONT DROPS THROUGH
THE AREA, SOME OF THE CAMS HAVE BEEN INDICATING THAT A FEW SHOWERS
MIGHT DEVELOP GENERALLY ACROSS SOUTH-CENTRAL AND SOUTHEAST VA/NE NC
LATER TODAY, SO HAVE KEPT SLIGHT CHANCE POPS IN THIS AREA. BEHIND
THE BACKDOOR COLD FRONT, TEMPS ABRUPTLY DROP INTO THE 40, WHICH
COULD BE QUITE THE SHOCK IN THE WAKE OF SUNDAY'S SPRING-TIME HIGHS.
THIS WILL OCCUR IN CONJUNCTION WITH BREEZY NORTHERLY FLOW, WHERE
WINDS WILL LIKELY GUSTS UP TO AROUND 20 MPH (20-25 MPH ALONG THE
COAST). COOLER OVERNIGHT SUNDAY WITH LOWS IN THE UPPER 20S TO LOWER
30S.
KEY MESSAGE 2...LIGHT SNOW AND SLEET OR FREEZING RAIN MONDAY NIGHT INTO
TUESDAY MORNING IS POSSIBLE, BUT PROBABILITIES FOR ANY
ACCUMULATION CONTINUE TO TREND DOWN.
A MORE UNSETTLED PATTERN WILL START NEXT WEEK OFF, WITH ADDITIONAL
CHANCES FOR PRECIPITATION, SOME OF WHICH MAY BE WINTER WEATHER. HIGH
PRESSURE ACROSS THE GREAT LAKES REGION ON SUNDAY WILL GRADUALLY
SLIDE EASTWARDS OVER THE NORTHEAST AND WEDGE DOWN ACROSS THE MID-
ATLANTIC. HAVE DROPPED TEMPERATURES CLOSER TO MOS GUIDANCE AS NBM
TEMPERATURES WERE MUCH HIGHER AND NOT ACCOUNTING FOR THE CAD SET UP
THAT IS LIKELY ON MONDAY. AS FOR ANY POSSIBLE WINTRY PRECIPITATION,
THE HIGH WILL INITIALLY BE IN A TYPICALLY FAVORABLE LOCATION FOR A
FOR POSSIBLE WINTER WEATHER, BUT THE DEPTH OF THE COLD AIR AND HOW
QUICKLY THE HIGH SHIFTS OFFSHORE WILL BE VERY IMPORTANT IN
DETERMINING THE PRECIP TYPE AS A SERIES OF SHORTWAVES MOVE THROUGH
ALOFT MONDAY INTO EARLY TUESDAY. SNOW OR EVEN SLEET AND POTENTIALLY
SOME LIGHT FREEZING RAIN ARE POSSIBLE OVER PORTIONS OF THE AREA LATE
MONDAY INTO EARLY TUESDAY. WHILE THERE STILL REMAINS DISAGREEMENT
BETWEEN SOME OF THE GLOBAL MODELS, THE OVERALL CONSENSUS IS THAT THE
HIGH TO OUR NORTH WILL BE VERY PROGRESSIVE, SO THE COLDER AIR DOES
NOT STAY IN PLACE LONG ACROSS THE AREA. DUE TO DROPPING PROBS FOR
BOTH SNOW AND ICE ACCUMULATIONS AND VERY MARGINAL TEMPERATURES
EXPECTED DURING THE EVENT, HAVE BASICALLY REMOVED ANY ACCUMULATION
OF WINTRY WEATHER. WHILE THERE IS A LOW CHANCE FOR SOME ICE
ACCUMULATIONS, IT WILL LIKELY BE LIMITED TO THE TREE TOPS AND WILL
LIKELY NOT LEAD TO ANY IMPACTS. AS THERE IS STILL SOME UNCERTAINTY
REGARDING THIS EVENT, WE WILL CONTINUE TO MONITOR THIS SYSTEM FOR
ANY CHANGES IN AMOUNTS/EVOLUTION/TIMING AND ADJUST THE FORECAST AS
NECESSARY.
KEY MESSAGE 3...A SIGNIFICANT WARMING TREND IS LIKELY STARTING
THE MIDDLE OF NEXT WEEK THROUGH THE WEEKEND.
AFTER THE COOLER START TO THE WEEK, WARMER WEATHER IS ON THEY WAY.
ENSEMBLE GUIDANCE IS DEPICTING A LARGE UPPER RIDGE OVER THE EASTERN
U.S, WITH 850 MB TEMPERATURE ANOMALIES WELL ABOVE AVERAGE. IF THIS
SET-UP COMES TO FRUITION, TEMPERATURES WILL RISE TO WELL ABOVE
NORMAL, WITH HIGHS POTENTIALLY REACHING THE LOWER TO MID 70S BY LATE
NEXT WEEK AND LOWS ONLY DROPPING INTO THE UPPER 40S TO NEAR 50F. BY
THE WEEKEND, SOME GUIDANCE IS EDGING VERY CLOSE TO THE 80F MARK FOR
INLAND AREAS. THIS WEEK WILL BE THERE FIRST TIME THAT RICHMOND WILL
HAVE SEEN HIGHS >=70F SINCE RIGHT BEFORE THANKSGIVING. THE LAST TIME
THAT 70F WAS NOT REACHED DURING METEOROLOGICAL WINTER WAS DURING THE
2009-2010 WINTER. WHILE THERE IS GOOD AGREEMENT ON THE OVERALL
SYNOPTIC PATTERN, THERE IS ALWAYS A CHANCE THAT THE COLDER AIRMASS
ASSOCIATED WITH THE BACKDOOR COLD FRONT OVER STAYS ITS WELCOME AND
KEEPS TEMPERATURES COOLER THAN FORECAST. HOWEVER, WITH THE STRENGTH
OF THE RIDGE AND THE CONTINUED VERY GOOD ENSEMBLE CONSENSUS, THIS
SCENARIO IS LOOKING MORE AND MORE UNLIKELY, SO HAVE CONTINUED TO
MAINTAIN WELL ABOVE NORMAL TEMPERATURES LATE WEEK AND INTO THE
WEEKEND. A SERIES OF WEAK FRONTS BRING LOW-END CHANCES FOR SHOWERS
TOWARD THE END OF NEXT WEEK AS WELL, BUT WIDESPREAD RAINFALL IS NOT
EXPECTED.
AVIATION /07Z SUNDAY THROUGH THURSDAY/
AS OF 1240 AM EST SUNDAY...
ECG AND PHF ARE ALREADY OBSERVING THE DEVELOPMENT OF SOME PATCHY FOG
THIS MORNING, SO HAVE INCLUDED BR IN THOSE TAFS THROUGH AROUND OR
JUST AFTER SUNRISE. CANNOT COUNT OUT FOG DEVELOPMENT AT THE OTHER
SITES, SO WE WILL CONTINUE TO MONITOR VIS OVER THE NEXT FEW HOURS
AND AMEND IF NECESSARY. OTHERWISE, GENERALLY LIGHT SOUTHWEST WINDS
WILL CONTINUE THROUGH THE AFTERNOON BEFORE SHIFTING TO THE N/NE AND
INCREASING AS A BACKDOOR COLD FRONT MOVES THROUGH THE AREA. GUSTS OF
AROUND 20 KTS ARE EXPECTED FOR A FEW HOURS THIS
AFTERNOON/EVENING IN THE WAKE OF THE FRONT, BUT WILL TREND
DOWNWARDS OVERNIGHT. THERE IS A CHANCE FOR A FEW SHOWERS ALONG
THE FRONT, MAINLY AT THE SOUTHERN TERMINALS, BUT CONFIDENCE IS
TOO LOW TO INCLUDE ANY MENTION OF THEM AT THIS TIME.
OUTLOOK: HIGH PRESSURE BUILDS DOWN INTO THE REGION SUNDAY NIGHT
INTO MONDAY AS SEVERAL DISTURBANCES PASS THROUGH. THESE ARE
LIKELY TO BRING ADDITIONAL PERIODS OF LIGHT PRECIP FOR THE
BEGINNING OF NEXT WEEK AND POTENTIAL FLIGHT RESTRICTIONS. A
BRIEF PERIOD OF WINTRY PRECIPITATION IS POSSIBLE AT RIC/SBY
MONDAY NIGHT INTO TUESDAY.
MARINE
AS OF 250 PM EST SATURDAY...
KEY MESSAGES:
- SUB-SCA CONDITIONS WITH RELATIVELY LIGHT FLOW FROM HIGH PRESSURE
OVER THE AREA THROUGH SUNDAY MORNING.
- SCAS HAVE BEEN ISSUED FOR THE CHESAPEAKE BAY, COASTAL WATERS,
LOWER JAMES RIVER AND CURRITUCK SOUND AS A BACKDOOR COLD FRONT FROM
STRONG HIGH PRESSURE TO THE NE CROSSES THE WATERS SUNDAY AFTERNOON.
LATEST WX ANALYSIS SHOWS HIGH PRESSURE OVER THE AREA THIS AFTERNOON
WITH A LINGERING UPPER TROUGH, WITH SUBSEQUENT SURFACE STATIONARY
FRONT, OFFSHORE TO THE SE. THE HIGH PRESSURE OVER THE AREA ALLOWS
FOR RELATIVELY LIGHT N/NE WINDS AROUND 5-10 KT. WAVES AND SEAS ARE
CURRENTLY ~1 FT IN THE CHES. BAY AND 2-3 FT IN THE COASTAL WATERS.
WINDS WILL BECOME S/SW TONIGHT STILL AROUND 5-10 KT AHEAD OF THE
NEXT COLD FRONT APPROACHING FROM THE N. MARINE FOG/ LOW STRATUS
CLOUDS COULD DEVELOP OVERNIGHT ACROSS THE COASTAL WATERS AND CHES.
BAY AS DEWPOINTS REACH NEAR WATER TEMPS (MID TO UPPER 30S) WITH
LIGHT WINDS. WILL CONTINUE TO MONITOR TRENDS AND CAMERAS FOR THE
POSSIBILITY OF NEEDING MARINE DENSE FOG ADVISORIES.
BEGINNING SUNDAY AFTERNOON FOR THE MIDDLE CHES. BAY AND NORTHERN
COASTAL WATERS, THE BACKDOOR COLD FRONT DROPS ACROSS THE LOCAL
WATERS. MODELS CONTINUE TO SHOW A STRONG (~1040 MB), PROGRESSIVE
HIGH PRESSURE TO THE NORTH OF THE AREA PUSHING CAA OVER THE WATERS,
AS WELL AS FAIRLY STRONG PRESSURE RISES, SUNDAY AFTERNOON INTO
MONDAY MORNING. LATEST CAM MODELS TRENDS THE COLD FRONT MOVING
THROUGH THE AREA SLIGHTLY FAST, NOW WITH BACKDOOR FRONT CROSSING THE
MIDDLE CHES. BAY AND NORTHERN COASTAL WATERS SUNDAY AFTERNOON, AND
CROSSING THE NC COASTAL WATERS SUNDAY EVENING. ELEVATED N/NE WINDS
AROUND 15-20 KT AND GUSTS TO 25 KT ARE EXPECTED THROUGH MONDAY
MORNING. AN INITIAL BURST WITH THE FRONT COULD HAVE GUSTS UP TO 30
KT. THE UPPER RIVERS ARE MORE MARGINAL, DUE TO THE WIND DIRECTION.
SEAS WILL INCREASE TO 4-5 FT N AND 5-7 FT S, AND WAVES TO 3-4 FT,
PEAKING LATE SUNDAY INTO EARLY MONDAY MORNING. WITH THIS, SMALL
CRAFT ADVISORIES HAVE BEEN ISSUED FOR THE CHESAPEAKE BAY, COASTAL
WATERS, LOWER JAMES RIVER AND CURRITUCK SOUND, WITH STAGGERING START
TIMES FROM N TO S BEGINNING SUNDAY AFTERNOON. 5 FT SEAS WILL LIKELY
LINGER INTO MONDAY AFTERNOON IN THE SOUTHERN WATERS. THEN, BENIGN
MARINE CONDITIONS RETURN FOR THE WEEK.
