AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
758 PM EST SAT DEC 6 2025
SYNOPSIS
HIGH PRESSURE BECOMES CENTERED ACROSS THE REGION TONIGHT, WITH
AREAS OF FOG AND FREEZING FOG POSSIBLE. PRIMARILY DRY CONDITIONS
ARE EXPECTED SUNDAY, BUT A WEAK LOW PRESSURE SYSTEM BRINGS A
CHANCE FOR RAIN AND SNOW MONDAY. MAINLY DRY FOR TUESDAY THROUGH
THURSDAY, WITH SHOWER CHANCES INCREASING WITH THE NEXT COLD
FRONT LATE IN THE WEEK.
NEAR TERM /THROUGH SUNDAY/
AS OF 800 PM EST SATURDAY...
KEY MESSAGES:
- FREEZING FOG IS EXPECTED INLAND TONIGHT, DRY AND A BIT WARMER
SUNDAY.
A FREEZING FOG ADVISORY HAS BEEN ISSUED FOR OUR WESTERN TIER OF
COUNTIES AS OF 8 PM EST. TEMPERATURES WILL CONTINUE TO DROP THIS
EVENING, FALLING BACK INTO THE 20S TONIGHT. THIS COMBINED WITH
WIDESPREAD VISIBILITIES OF 1/4 SM (OR LESS) WILL LEAD TO THE
POTENTIAL FOR SLIPPERY CONDITIONS TONIGHT INTO SUNDAY MORNING,
ESPECIALLY ON BRIDGES, ELEVATED SURFACES, OR UNTREATED ROADWAYS.
EXPECT THE FOG TO CONTINUE TO SPREAD EAST OVER THE NEXT FEW
HOURS AND AN EXPANSION OF THE ADVISORY TO THE EAST IS LIKELY.
PREVIOUS DISCUSSION: THE LATEST WX ANALYSIS SHOWS A RATHER WEAK
PRESSURE GRADIENT OVER THE LOCAL AREA, WITH WIDESPREAD LOW
CLOUDS HANGING ON EAST OF THE BLUE RIDGE. TEMPERATURES HAVE
REMAINED QUITE COLD IN THE THE PIEDMONT, IN THE LOW-MID 30S
WHICH IS ABOUT 10 DEGREES BELOW NBM FORECASTED READINGS AS OF 3
PM. SOMEWHAT WARMER AIR IS IN PLACE ACROSS SE VA/NE NC
(TEMPERATURES IN THE 40S).
CHALLENGING FORECAST TONIGHT WITH RESPECT TO FOG/FREEZING FOG
AS THE MODELS CONTINUE TO STRONGLY SUGGEST THAT IT BECOMES
WIDESPREAD ALONG AND W OF I-95 AFTER MIDNIGHT, WHILE THE LATEST
CONDITIONS HAVE BEEN MUCH SLOWER TO ALLOW FOR ANY CLEARING OVER
THE CWA (WHICH LEADS TO LOWER CONFIDENCE). FOR NOW, WILL STILL
SHOW SOME CLEARING THIS EVENING, WITH LIGHT WINDS CONDUCIVE TO
RADIATIONAL COOLING LATER TONIGHT. NAM AND GFS BUFKIT SOUNDINGS
CONTINUE TO DEPICT BOUNDARY LEVEL SATURATION WITH THE POTENTIAL
FOR MORE WIDESPREAD AND DENSE FOG/FREEZING FOG. LOWS TONIGHT
FALL INTO THE 20S FOR MOST OF THE AREA WITH LOW 30S NEAR THE
BAY/COAST. AFTER MORNING FOG/FREEZING FOG, SUNDAY WOULD
EVENTUALLY SEE PARTIAL SUNSHINE. ESPECIALLY SOUTH, ALONG WITH
MILDER TEMPERATURES RISING INTO THE LOW-MID 40S NORTH, WITH
LOWER 50S SE.
SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/
AS OF 310 PM EST SATURDAY...
KEY MESSAGES:
- WEAK LOW PRESSURE OFF THE SE COAST WILL BRING A CHANCE FOR
RAIN/SNOW CHANGING TO SNOW MONDAY.
- DRY AND COLD TUESDAY.
HIGH PRESSURE WILL BE OFFSHORE SUNDAY NIGHT, ALLOWING LOW LEVEL
FLOW TO BECOME SOUTHERLY AHEAD OF AN APPROACHING COLD FRONT.
MEANWHILE, WEAK LOW PRESSURE LIFTS ENE OFF THE COAST OF NORTHERN
FLORIDA, GRADUALLY STRENGTHENING OFF THE SE COAST ON MONDAY. ALL
OF THE MODELS HAVE TRENDED FARTHER NORTH WITH THE PRECIP CHANCES
MONDAY, WITH A SIMILAR TEMPERATURE PROFILE TO PREVIOUS RUNS.
AS A SHORT WAVE ALOFT TRAVERSES THE REGION ON MONDAY, EXPECT AT
LEAST A CHC FOR PRECIP FOR MOST OF THE CWA (GENERALLY HIGHEST
POPS ACROSS THE SOUTH). DEEP LAYER MOISTURE IS STILL SOMEWHAT
LIMITED BEHIND THE SURFACE COLD FRONT, BUT THE TRENDS ARE WETTER
SO WOULD NOT RULE OUT THE POTENTIAL FOR QPF AMOUNTS TO ~0.25"
AND THINK THE NBM IS BEHIND ON THE TRENDS. WITH ~1030 MB SFC
HIGH PRESSURE SLIDING EAST FROM THE GREAT LAKES INTO NY/PA
DURING THE DAY MONDAY, THERE WILL BE A GOOD FEED OF COLD AIR
INTO THE MID-ATLANTIC, WITH VERY COLD AIR ALOFT. LATEST 12Z/06
GEFS/GEPS/ENS HAVE TRENDED SIGNIFICANTLY UPWARD AND NOW SHOW
20-60% CHANCES FOR AT LEAST 1" SNOWFALL ACROSS CENTRAL AND SOUTH
CENTRAL VA (ASSUMING A 10:1 SLR) WHICH MAY ACTUALLY END UP
BEING MORE LIKE 15:1 LATER IN THE DAY. WILL MENTION THE WINTER
WX POTENTIAL MONDAY IN THE HWO FOR NOW AND CONTINUE TO MONITOR
MODEL TRENDS OVER THE NEXT FEW CYCLES AS THIS WILL BEAR WATCHING.
HIGH TEMPS MONDAY TOP OUT IN THE MID 30S NW TO THE LOW 40S SE
(BUT IF MOISTURE LINGERS MON EVENING EVEN SE ZONES HAVE SOME
SNOW POTENTIAL).
VERY COLD AIR MOVES INTO THE REGION MONDAY NIGHT WITH LOWS IN
THE MID TO UPPER TEENS INLAND, MAINLY LOW TO MID 20S NEAR THE
COAST. HIGH PRESSURE OVER THE REGION ON TUESDAY WILL BECOME
CENTERED SOUTH OF THE AREA LATE IN THE DAY. MOSTLY SUNNY, BUT
COLD TUESDAY WITH HIGHS IN THE MID/UPPER 30S NW TO THE MID 40S
SE.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
AS OF 320 PM EST SATURDAY...
- MILDER WEDNESDAY AND THURSDAY.
- ANOTHER FRONT CROSSES THE REGION LATE IN THE WEEK WITH COLDER
TEMPS AND PRECIP POTENTIAL.
MEDIUM RANGE MODELS AND ENSEMBLES ARE IN DECENT AGREEMENT THAT
MIDWEEK SHOULD BE MILDER AS A DEEP UPPER TROUGH AMPLIFIES
ACROSS CENTRAL CANADA, WITH LOW PRESSURE TRACKING THROUGH THE
GREAT LAKES. THIS ALLOWS FOR AN INCREASING SW LOW LEVEL FLOW
WED, WITH HIGHS INTO THE 50S FOR MOST. REMAINING RELATIVELY MILD
WED NIGHT AND THURSDAY, WITH INCREASING RAIN CHANCES THURSDAY
NIGHT/FRIDAY AS THE NEXT SYSTEM IMPACTS THE REGION. PRECIP
POTENTIALLY CHANGES OVER TO A RAIN/SNOW MIX BEFORE ENDING FRIDAY
NIGHT. SATURDAY LOOKS DRY AND COLD AS HIGH PRESSURE BUILDS IN
FROM THE NW.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
AS OF 655 PM EST SATURDAY...
IFR CIGS ARE BEGINNING TO CREEP IN FROM THE NW (WITH RIC ALREADY
SEEING IFR CIGS) TO START OFF THE 07/00Z TAF PERIOD. AT THE
REMAINING TERMINALS, THERE IS A MIX OF MVFR TO VFR CIGS.
CONDITIONS DETERIORATE FROM NW TO SE THROUGHOUT THE NIGHT, WITH
WIDESPREAD IFR TO LIFR CIGS DEVELOPING OVER THE PIEDMONT. SBY
AND PHF LIKELY SEE A PERIOD OF IFR CIGS AROUND OR AFTER 06Z,
CONTINUING THROUGH ~14Z. AT RIC, IFR CIGS GRADUALLY DIMINISH TO
LIFR TONIGHT, WITH IFR/LIFR CIGS LINGERING THROUGH MUCH OF
SUNDAY AM. FINALLY, FOR THE SE TERMINALS (ORF/ECG), LOWER
CONFIDENCE IN IFR, THOUGH WE MAY SEE A BRIEF PERIOD OF IFR CIGS
DEVELOP BETWEEN 08 AND 14Z. IN REGARDS TO VSBYS, EXPECT FOG TO
DEVELOP OVER THE PIEDMONT AND WORK INTO RIC ~04Z. TEMPERATURES
FALL BELOW FREEZING AT RIC TONIGHT, WHICH WILL LIKELY LEAD FZFG
STARTING AROUND 08Z AND CONTINUING INTO SUNDAY AM. VSBYS MAY
DROP TO AS LOW AS 1/4 SM OR LESS, BUT DID NOT GO QUITE THAT LOW
JUST YET DUE TO THE WIDESPREAD CLOUD COVER. THE REMAINDER OF THE
SITES MAY ALSO SEE PATCHY TO AREAS OF FOG, WITH KPHF HAVING THE
NEXT BEST CHANCES...LOWER CONFIDENCE AT SBY AND AT THE SE
TERMINALS. CONDITIONS IMPROVE AFTER 14Z SUNDAY, THOUGH IFR CIGS
MAY TRY TO LINGER INTO EARLY SUNDAY AFTERNOON AT RIC. WINDS WILL
GENERALLY BE LIGHT AND VARIABLE THROUGH THE TAF PERIOD.
OUTLOOK: PRIMARILY VFR CONDITIONS RETURN BY SUNDAY NIGHT.
ANOTHER SYSTEM MONDAY MORNING MAY BRING DEGRADED FLIGHT
CONDITIONS TO THE TERMINALS.
MARINE
AS OF 300 PM EST SATURDAY...
- BENIGN MARINE CONDITIONS THROUGH SUNDAY.
- ANOTHER ROUND OF SCAS EXPECTED EARLY MONDAY AS A STRONG COLD FRONT
MOVES ACROSS THE LOCAL WATERS, WITH A BRIEF PERIOD OF GALE FORCE
GUSTS POSSIBLE.
- ANOTHER SYSTEM MAY BRING DEGRADED MARINE CONDITIONS TO THE AREA
WEDNESDAY THROUGH THE END OF THE WEEK.
WEAK HIGH PRESSURE IS SPREAD ACROSS THE SOUTHEAST, WITH AN AREA OF
LOW PRESSURE WELL OFFSHORE THIS AFTERNOON. THIS SET-UP HAS LED TO A
WEAK GRADIENT ACROSS THE LOCAL WATERS. MARINE OBSERVATION SITES ARE
MEASURING WINDS OF 5-10 KTS AND WAVES OF AROUND 1 FT IN THE BAY AND
SEAS RANGING BETWEEN 3-4 FT IN THE OCEAN. THE AFOREMENTIONED HIGH
WILL SLIDE NORTHEASTWARD ACROSS THE AREA OVER THE NEXT 24 HOURS,
LEADING TO BENIGN MARINE CONDITIONS THROUGH THE END OF THE WEEKEND.
WINDS WILL BECOME LIGHT AND VARIABLE, WITH WAVES REMAINING AROUND 1
FT AND SEAS SUBSIDING TO 2-3 FT IN THE OCEAN.
MARINE CONDITIONS WILL RAPIDLY DETERIORATE EARLY MONDAY MORNING AS A
COLD FRONT DROP THROUGH THE AREA. WINDS WILL REACH HIGH-END SCA
CONDITIONS FOR A MAJORITY OF THE DAY AND THROUGH THE FIRST PART OF
MONDAY NIGHT. THIS WILL OCCUR AS HIGH PRESSURE BUILDS SOUTHWARD
ACROSS THE REGION AND AN AREA OF LOW PRESSURE SKIRTS NORTHEAST OFF
THE CAROLINA COAST. WITH THE TIGHTENED GRADIENT IN PLACE, COMBINED
WITH STRONG CAA EXPECTED IN THE WAKE OF THIS FRONT, THERE WILL
LIKELY BE A PERIOD OF GALE-FORCE GUSTS ACCOMPANYING AT LEAST THE
INITIAL PUSH OF THIS DRIER, COLDER AIR. GUIDANCE HAS TRENDED UPWARDS
SOME IN THE SOUTHERN WATERS, THOUGH OUR IN-HOUSE WIND PROBS REMAIN
>50% FOR GALE FORCE GUSTS. THIS UPWARDS TREND IS THE RESULT OF A
SLIGHTLY CLOSER PLACEMENT OF THE LOW TO THE CAROLINA COAST AS
OPPOSED TO A LOW FURTHER OFFSHORE. THERE IS STILL SOME UNCERTAINTY
IN THE EXACT LOCATION OF THE LOW AT THIS TIME, AND WE WILL CONTINUE
TO IRON OUT THE EXACT DETAILS OVER THE NEXT FEW FORECAST CYCLES.
WITH THE LOWER CONFIDENCE AND THE POSSIBLE BRIEF NATURE OF THIS WIND
SURGE, HAVE HELD OF ON A GALE WATCH FOR NOW. HIGH PRESSURE IS
FORECAST TO BUILD ACROSS THE AREA LATE MONDAY NIGHT THROUGH TUESDAY,
AND WINDS WILL QUICKLY DIMINISH IN RESPONSE. THIS REPRIEVE FROM
WINDS WILL BE FLEETING AS ANOTHER SYSTEM APPROACHES THE REGION ON
WEDNESDAY. WINDS WILL BEGIN TO INCREASE WEDNESDAY MORNING AS A WARM
FRONT LIFTS ACROSS THE REGION, FOLLOWED BY ANOTHER STRONG COLD
FRONTAL PASSAGE BY LATE WEEK.
AS WINDS INCREASE ON MONDAY, WAVES WILL RAPIDLY BUILD TO 3-5 FT IN
THE BAY (HIGHEST AT THE MOUTH OF THE BAY) AND SEAS WILL BUILD TO 6-8
FT IN THE OCEAN. DESPITE AN EXPECTED DOWNTREND IN WINDS LATE MONDAY
NIGHT THROUGH TUESDAY, SEAS WILL BE SLOWER TO SUBSIDE AND WILL
LIKELY REMAIN NEAR OR JUST BRIEFLY DROP BELOW SCA CRITERIA BEFORE
BUILDING AGAIN WITH THE SECOND WIND SURGE FORECAST FOR WEDNESDAY.
