AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
214 AM EDT SUN JUL 6 2025
SYNOPSIS
MAINLY DRY CONDITIONS ARE EXPECTED THIS EVENING AS HIGH
PRESSURE BUILDS IN FROM THE NORTH, WITH LOWER HUMIDITY EXPECTED.
TROPICAL STORM CHANTAL ALONG THE SOUTHEAST COAST LIKELY MOVES
INLAND ACROSS THE CAROLINAS ON SUNDAY, BRINGING SHOWERS AND A
FEW EMBEDDED STORMS, PRIMARILY TO THE SOUTHERN HALF OF THE
AREA. BEHIND THE STORM, VERY WARM AND HUMID CONDITIONS ARE
EXPECTED FOR THE LATTER HALF OF NEXT WEEK, WITH MAINLY HIT OR
MISS TYPE AFTERNOON AND EVENING SHOWERS AND STORMS POSSIBLE
EACH DAY.
NEAR TERM /UNTIL 6 AM THIS MORNING/
AS OF 740 PM EDT SATURDAY...
KEY MESSAGE:
- A FEW SHOWERS POSSIBLE THIS AFTERNOON AND EVENING OVER NE NC.
- INCREASING CLOUDS TONIGHT WITH LOWS 63-75 (WARMEST FAR SE
COAST).
LATEST ANALYSIS CONTINUES TO SHOW BROAD 1023MB SFC HIGH
PRESSURE CENTERED JUST OFFSHORE OF THE DELMARVA, RIDGING BACK SW
INTO THE LOWER MID-ATLANTIC. TO THE SOUTH, TROPICAL STORM
CHANTAL IS POSITIONED OFF THE SC/GA COAST. ALOFT, HEIGHTS
CONTINUE TO INCREASE SLOWLY, AS AN UPPER LEVEL RIDGE CONTINUES
TO BUILD OVER THE NORTHERN AND CENTRAL APPALACHIANS. LIGHT E-SE
FLOW ALOFT CONTINUES TO SLOWLY INCREASE PW VALUES FROM <1" TO
1.5 TO 2" BY SUNDAY MORNING.
TEMPERATURES AS OF 730 PM RANGED FROM THE UPPER 70S TO LOWER 80S
UNDER A PARTLY TO MOSTLY SUNNY SKY (GREATER CLOUD COVER ACROSS
NE NC). THERE ARE A FEW SCATTERED SHOWERS NOTED ACROSS NE NC
ASSOCIATED WITH CONVECTIVE BANDS FROM TS CHANTAL. CLOUD COVER
INCREASES FROM THE SOUTH OVERNIGHT INTO SUN MORNING, AS TS
CHANTAL DRIFTS SLOWLY TOWARD THE SC COAST. REMAINING MAINLY DRY
THIS EVENING, THOUGH AS MORE EFFICIENT TRANSPORT TROPICAL
MOISTURE STARTS TO STREAM NNE INTO THE AREA AND PWS STREAM BACK
AOA 1.5"-2", EXPECT MORE CONSIDERABLE CLOUD COVER WITH SHOWER
CHANCES CONTINUING ACROSS NE NC TONIGHT INTO THE DAY SUN. EARLY
MORNING LOWS RANGE FROM THE MID 60S NW TO THE MID 70S SE.
SHORT TERM /6 AM THIS MORNING THROUGH MONDAY NIGHT/
AS OF 245 PM EDT SATURDAY...
KEY MESSAGE:
- MOISTURE AND PRECIP CHANCES INCREASE SUNDAY INTO MONDAY AS
TROPICAL STORM CHANTAL LIFTS NORTHWARD.
- MAIN THREATS FROM CHANTAL WILL BE LOCALLY HEAVY RAINFALL,
ESPECIALLY HAMPTON ROADS AND NORTHEAST NC AND INCREASED RISK
FOR RIP CURRENTS.
HUMIDITY AND RAIN CHANCES RETURN TO THE AREA SUNDAY, AS
TROPICAL MOISTURE MOVES BACK IN WITH THE SE FLOW AHEAD OF
CHANTAL. THE SYSTEM IS EXPECTED TO MOVE OVER LAND IN SC BY
SUNDAY AFTERNOON. AT THAT POINT, THE SYSTEM QUICKLY WEAKENS
TO A BROAD AREA OF LOW PRESSURE AND PROGRESSES N UP THE COAST
THROUGH MONDAY BEFORE WASHING OUT.
SCATTERED SHOWERS LOOK TO DEVELOP ACROSS E NC SUNDAY MORNING,
WITH SHOWERS/STORMS TO THEN SPREAD ACROSS THE AREA IN THE
AFTERNOON, BUT CONCENTRATED MAINLY ACROSS THE COASTAL PLAIN.
NOT EXPECTING MUCH IN THE WAY OF SEVERE STORMS, BUT WITH PWATS
RISING TO 2 TO 2.5" OVER MUCH OF THE AREA (HIGHEST SE), ANY
SHOWERS WILL BE CAPABLE OF LOCALLY HEAVY DOWNPOURS. ALL BUT THE
EASTERN SHORE ARE NOW IN AN ERO FOR TOMORROW (SUNDAY).
NOCTURNAL STABILIZATION SHOULD DIMINISH AREAL COVERAGE OF
SHOWERS AND STORMS ONCE AGAIN, AT LEAST INITIALLY SUNDAY NIGHT.
HOWEVER, AS THE WEAKENING CIRCULATION CONTINUES NORTH AND CONTINUES
TO PULL IN TROPICAL MOISTURE, POPS INCREASE IN COVERAGE ALL
OVER AGAIN LATE SUNDAY NIGHT AND MONDAY. HEAVY RAINFALL REMAINS
THE MAIN SENSIBLE WX THREAT. THERE REMAINS A STRONG MODEL
SIGNAL FOR IVT OF 600-800+ KG/M/S LIFTING ACROSS THE COASTAL
PLAIN LATE SUNDAY NIGHT AND MONDAY MORNING (95-98% PERCENTILE OF
CLIMO). GIVEN RECENT RAINS OF EARLIER THIS WEEK, THIS COULD
EASILY RESULT IN ADDITIONAL ISOLATED TO SCATTERED INSTANCES OF
FLASH FLOODING, AND COMMUNITIES EAST OF I-95 ALONG THE COASTAL
PLAIN SHOULD CONTINUE TO MONITOR THE RAINFALL FORECAST CLOSELY
IN THE COMING DAY OR SO. THE MARGINAL ERO IS NOW IN PLACE FOR
THE ENTIRE AREA ON DAY 3 (MONDAY). PRECIP LOOKS TO MOSTLY COME
TO AN END WITH THE LOSS OF DAYTIME HEATING MONDAY NIGHT, BUT A
FEW SHOWERS COULD LINGER BY THE COAST OVERNIGHT. HIGHS ON BOTH
SUN AND MON WILL BE IN THE UPPER 80S. LOWS BOTH NIGHTS WILL BE
IN THE LOW- MID 70S.
LONG TERM /TUESDAY THROUGH SATURDAY/
AS OF 245 PM EDT SATURDAY...
KEY MESSAGES:
- BECOMING HOT AND HUMID TUESDAY THROUGH THE END OF THE WEEK
WITH MAINLY AFTERNOON/EVENING STORM CHANCES.
AS THE REMNANTS OF CHANTAL DEPART THE REGION, THE REST OF THE
WEEK LOOKS SEASONABLY WARM AND RATHER HUMID, WHILE REMAINING
UNSETTLED, DUE TO WEAK TROUGHINESS LINGERING ACROSS THE MID-
ATLANTIC AND A COLD FRONT APPROACHING FROM THE NORTHWEST BY LATE
IN THE WEEK. STORMS WILL LIKELY BE DIURNAL IN NATURE WITH
CHANCES EACH AFTERNOON AND EVENING. WILL SEE SCATTERED ACTIVITY
TUES- WED, POTENTIALLY BECOMING A LITTLE MORE WIDESPREAD THURS-
FRI AS THE FLOW ALOFT INCREASES AHEAD OF THE APPROACHING FRONT.
HIGHS WILL BE IN THE LOW 90S TUES AND WED, THEN PERHAPS A
COUPLE DEGREES COOLER TO END THE WEEK WITH INCREASED CLOUDS AND
MORE WIDESPREAD SHOWERS. THE RETURN OF TEMPS IN THE 90S AND THE
HUMIDITY ALSO MEANS A RETURN TO HEAT INDICES RIGHT AROUND 100
DEGREES. HAVE UNDERCUT HEAT INDICES A BIT ONCE AGAIN, WITH THE
IDEA THAT BL REMAINS MIXED ENOUGH TUE-WED TO BREAK WIDESPREAD
UPPER 70S TD VALUES CURRENTLY SUGGESTED BY THE NBM.
AVIATION /06Z SUNDAY THROUGH THURSDAY/
AS OF 150 AM EDT SUNDAY...
VFR PREVAILS ACROSS THE TERMINALS TO START THE 06Z TAF PERIOD.
CLOUD COVER WILL INCREASE ACROSS THE AREA THROUGH THE PERIOD AS
TS CHANTAL MAKES LANDFALL OVER SC AND THE REMNANTS DRIFT N
TOWARD THE LOCAL AREA. BY MID AFTERNOON, THE TERMINALS (EXCEPT
PERHAPS SBY) SHOULD BE UNDER BKN CLOUD COVER. CIGS LOOK TO
REMAIN VFR THROUGH ~12Z, THEN DROPPING TO MVFR FOR ECG/ORF/PHF.
COULD SEE A BRIEF RETURN TO VFR THIS EVENING BEFORE CIGS DROP
FOR ALL TERMINALS OVERNIGHT. A FEW ROUNDS OF SCATTERED
SHOWERS/STORMS LATER THIS MORNING THROUGH TOMORROW WILL MEAN
MULTIPLE OPPORTUNITIES TO IMPACT TERMINALS. ECG WILL BE THE
FIRST TO SEE PRECIP AS RAIN MOVES IN FROM THE S. SBY LIKELY
STAYS DRY THROUGH TOMORROW MORNING. VSBYS COULD BE BRIEFLY
IMPACTED AS HEAVY RAIN IS POSSIBLE. SE WINDS INCREASE TO 10-15KT
TODAY, THEN BACK TO 5-10KT OVERNIGHT.
OUTLOOK: SCATTERED TO WIDESPREAD SHOWERS/STORMS ARE LIKELY
ACROSS ALL AREAS ON MON, WITH ADDITIONAL PERIODS OF IFR/MVFR
POSSIBLE. VERY WARM, HUMID CONDITIONS FOLLOW FOR TUE THROUGH
THU, WITH LATE DAY AND EVENING SHOWERS AND STORMS POSSIBLE,
ALONG WITH SOME EARLY MORNING GROUND FOG/STRATUS.
MARINE
AS OF 210 AM EDT SUNDAY...
KEY MESSAGES:
- THERE IS A HIGH RISK OF RIP CURRENTS ACROSS THE SOUTHERN BEACHES
TODAY.
- THE VAST MAJORITY OF MARINE IMPACTS FROM TROPICAL STORM
CHANTAL WILL REMAIN WELL TO THE SOUTH OF THE LOCAL WATERS,
BUT SCAS HAVE BEEN ISSUED FOR THE BAY AND COASTAL WATERS SOUTH
OF CAPE CHARLES FROM THIS AFTERNOON THROUGH PART OF TONIGHT.
- WINDS DIMINISH SLIGHTLY MONDAY MORNING, BUT ANOTHER ROUND OF BRIEF
SCA CONDITIONS IS POSSIBLE MONDAY AFTERNOON.
- SUB-SCA CONDITIONS PREVAIL FROM TUESDAY-FRIDAY WITH DAILY
THUNDERSTORM CHANCES.
SUB-SCA MARINE CONDITIONS PREVAIL EARLY THIS MORNING WITH WEAK HIGH
PRESSURE OFFSHORE AND TROPICAL STORM CHANTAL TO OUR SOUTH (ABOUT TO
MAKE LANDFALL IN SC). WINDS ARE ESE AT ~10 KT WITH ~3 FT SEAS AND 1-
2 FT WAVES. AFTER MAKING LANDFALL IN SC, CHANTAL IS EXPECTED TO
WEAKEN WHILE MOVING MORE TO THE N THEN NE LATER TODAY INTO TONIGHT.
THE REMNANTS OF CHANTAL LIKELY CROSS THE LOCAL AREA ON MONDAY. THE
PRESSURE GRADIENT WILL INCREASE AHEAD OF CHANTAL LATER TODAY,
ALLOWING WINDS TO BECOME SE AND INCREASE TO 15-20 KT (WITH 20-25 KT
GUSTS) BY THIS AFTERNOON. THESE ELEVATED WINDS WILL PERSIST THROUGH
THE FIRST PART OF TONIGHT BEFORE DECREASING BY A FEW KNOTS EARLY
MONDAY MORNING. LOCAL WIND PROBS FOR 18+ KT HAVE INCREASED TO 50-75%
ON THE BAY FOR A 3-6 HOUR PERIOD LATE THIS AFTN-LATE THIS EVENING.
THEREFORE, WENT AHEAD AND ISSUED SCAS FOR THE BAY/CURRITUCK SOUND
FROM 17-20Z/1-4 PM THROUGH 05Z/1 AM. ALSO, SEAS BUILD TO 3-4 FT N/4-
5 FT S BY LATE THIS AFTN, SO HAVE ISSUED SCAS FOR THE COASTAL WATERS
S OF CAPE CHARLES FROM 20Z/4 PM-08Z/4 AM. WINDS BECOME MORE
SOUTHERLY AND INCREASE ONCE AGAIN TO 15-20 KT BY MIDDAY/AFTN ON
MONDAY AS THE REMNANTS OF CHANTAL MOVES OUT OF THE AREA. THE CURRENT
ROUND OF SCAS MAY NEED TO BE EXTENDED THROUGH MONDAY, AND THE
NORTHERN THREE COASTAL ZONES MAY NEED TO BE ADDED GIVEN THAT SEAS
COULD INCREASE TO 4-5 FT WITH THE ELEVATED SOUTHERLY WINDS.
REGARDLESS, WINDS ARE FORECAST DIMINISH MONDAY NIGHT/TUESDAY AS THE
LOW SLOWLY EXITS. VARIABLE MARINE CONDITIONS RETURN TOWARD THE
MIDDLE OF NEXT WEEK WITH AFTERNOON SEA BREEZES AND DIURNAL
SHOWER/STORM ACTIVITY.
THERE IS A HIGH RISK OF RIP CURRENTS ACROSS THE SOUTHERN BEACHES
TODAY WITH A MODERATE RISK ACROSS THE NORTHERN BEACHES. THIS IS DUE
TO 3-4 FT NEARSHORE WAVES ACROSS THE SOUTHERN BEACHES AND HIGH
PERIOD SWELL WITH PERIODS UP TO 15 SECONDS POSSIBLE ACROSS ALL AREA
BEACHES. THE RIP CURRENT RISK WILL BE MODERATE TO HIGH ON MONDAY AS
WELL ACROSS ALL AREA BEACHES.
