AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
231 AM EDT FRI JUL 11 2025
SYNOPSIS
AN UNSETTLED WEATHER PATTERN IS EXPECTED TO PERSIST THROUGH
THE WEEKEND, WITH ISOLATED TO SCATTERED THUNDERSTORMS EACH DAY.
THE POTENTIAL FOR AFTERNOON THUNDERSTORMS WILL CONTINUE EARLY
NEXT WEEK.
NEAR TERM /THROUGH TONIGHT/
AS OF 230 AM EDT FRIDAY...
KEY MESSAGES:
- ISOLATED TO SCATTERED AFTERNOON/EVENING THUNDERSTORMS ARE EXPECTED
NEAR THE COAST TODAY, WITH ISOLATED STORMS AT MOST INLAND.
- LOCALIZED FLASH FLOODING IS STILL POSSIBLE TODAY.
AN UPPER TROUGH IS SLOWLY PUSHING EAST OF THE AREA EARLY THIS
MORNING AS RIDGING REMAINS IN PLACE OFF THE SE CONUS COAST. THERE
ARE NOT ANY WELL DEFINED SURFACE FEATURES LOCALLY, BUT BERMUDA HIGH
PRESSURE REMAINS OFFSHORE. TSTMS HAVE DISSIPATED, WITH A FEW
LINGERING SHOWERS IN NE NC. THE UPPER TROUGH THAT HELPED TO PROVIDE
THE NECESSARY LIFT FOR CONVECTION THE PAST TWO DAYS WILL SHIFT
OFFSHORE TODAY. THIS WILL LEAD TO HEIGHT RISES. IT WILL BE
SEASONABLE TODAY WITH HIGHS AROUND 90F AND DEW PTS IN THE LOWER-MID
70S. DESPITE THE HEIGHT RISES, THE ATMOSPHERE WILL REMAIN UNCAPPED
WITH MLCAPE RISING TO ~2000 J/KG BY THE AFTERNOON (ALONG WITH VERY
WEAK SHEAR). ISOLATED TO SCATTERED (SLOW MOVING) TSTMS WILL LIKELY
DEVELOP BY EARLY-MID AFTN ALONG SEA BREEZE BOUNDARIES NEAR THE
COAST, WITH PERHAPS AN ISOLATED STORM OR TWO INLAND. CAN'T RULE OUT
A STRONGER STORM OR TWO, WITH LOCALIZED URBAN/FLASH FLOODING
POSSIBLE. DESPITE THE LOWER DEGREE OF STORM COVERAGE, THE HREF STILL
HAS A 10% PROBABILITY OF 3" OF RAIN IN 3 HOURS NEAR THE COAST LATER
TODAY GIVEN THE VERY SLOW EXPECTED STORM MOTIONS. TSTMS QUICKLY
DISSIPATE AFTER 9-10 PM, LEADING TO WARM/HUMID WX TONIGHT WITH LOWS
IN THE LOWER-MID 70S.
SHORT TERM /SATURDAY THROUGH SUNDAY/
AS OF 230 AM EDT FRIDAY...
KEY MESSAGES:
- ISOLATED TO SCATTERED THUNDERSTORMS ARE STILL EXPECTED FROM THIS
WEEKEND AS THE UNSETTLED PATTERN CONTINUES.
- HIGHLY LOCALIZED FLOODING REMAINS A THREAT THROUGH THE WEEKEND.
THE UPPER HEIGHT RISES ARE EXPECTED TO CONTINUE THROUGH THE WEEKEND
AS RIDGING TRIES TO BUILD BACK INTO THE AREA. MEANWHILE, A VERY WEAK
BACKDOOR FRONT CROSSES THE EASTERN SHORE ON SATURDAY AND LINGERS IN
THE AREA ON SUNDAY. IT WILL BE HOTTER ON SATURDAY WITH LOW TO
LOCALLY MID 90S POSSIBLE INLAND AND MAX HEAT INDICES OF 100-104F IN
A FEW LOCATIONS. TEMPS ON SUNDAY ARE FORECAST TO BE A FEW DEGREES
LOWER THAN WHAT'S EXPECTED ON SATURDAY. DIURNALLY DRIVEN TSTMS WILL
CONTINUE EACH DAY THIS WEEKEND (LIKELY FOCUSED ALONG AND WEST OF THE
BACKDOOR FRONT) AS THE ENVIRONMENT WILL STILL BE UNCAPPED AND MOIST.
WITH THE SATURATED GROUND FROM YESTERDAY AND TODAY, LOCALIZED
FLOODING CAN'T BE RULED OUT THROUGH THE WEEKEND AS PWAT VALUES ARE
EXPECTED TO BE ABOVE THE 90TH PERCENTILE FOR THIS TIME OF YEAR.
LOCALIZED RAINFALL TOTALS OF 1-3" ARE POSSIBLE EACH DAY. A LOW-END
THREAT FOR DAMAGING WIND GUSTS EXISTS ON BOTH DAYS (MAINLY DUE TO
HIGHLY LOCALIZED DOWNBURSTS AS THE FLOW ALOFT/SHEAR WILL REMAIN VERY
WEAK).
LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
AS OF 230 AM EDT FRIDAY...
KEY MESSAGE:
- STAYING SEASONABLY WARM AND HUMID FOR MUCH OF NEXT WEEK WITH
MAINLY AFTERNOON/EVENING STORM CHANCES PERSISTING.
A MORE SEASONABLE WEATHER PATTERN IS EXPECTED TO CONTINUE FROM THE
EARLY TO MIDDLE PART OF THE WEEK. WHILE THE STRONGER WESTERLIES
REMAIN TO OUR NORTH THROUGH THE PERIOD, A SUBTLE UPPER SHORTWAVE IS
PROGGED TO CROSS THE AREA ON MONDAY. THIS WILL LEAD TO INCREASED
COVERAGE OF MAINLY AFTERNOON/EVENING TSTMS. THE MAIN CONCERN WITH
ANY STORMS ON MONDAY WILL BE FLOODING, ALTHOUGH EXACT DETAILS ARE
HARD TO PINPOINT THIS FAR OUT. THAT SHORTWAVE MOVES OFFSHORE BY TUE.
UPPER RIDGING THEN TRIES TO BUILD BACK INTO THE AREA FROM TUE-THU,
ALTHOUGH ISOLATED TO SCATTERED AFTN/EVENING TSTMS ARE POSSIBLE EACH
DAY. HIGHS NEXT WEEK WILL BE AROUND SEASONAL AVERAGES FOR THIS TIME
OF YEAR (UPPER 80S/AROUND 90F), ALTHOUGH IT MAY WARM UP A BIT BY
NEXT THURSDAY/FRIDAY (BUT VERY LIKELY NOT TO THE LEVELS THAT WE SAW
DURING OUR JUNE HEAT WAVE).
AVIATION /07Z FRIDAY THROUGH TUESDAY/
AS OF 130 AM EDT FRIDAY...
MAINLY VFR CONDITIONS PREVAIL AT THIS HOUR, WITH PATCHY IFR
STRATUS NOTED. THE IFR STRATUS IS EXPECTED TO BECOME MORE
WIDESPREAD DURING THE 07-13Z TIMEFRAME, BUT NOT CONFIDENT THAT
IT WILL BE PREVAILING FOR SEVERAL HOURS. THUS, HAVE ACCOUNTED
FOR IT W/ TEMPO GROUPS IN THE TAFS. ANY LINGERING LOW STRATUS
WILL DISSIPATE BY MID TO LATE MORNING. ISOLATED TO SCATTERED
TSTMS ARE EXPECTED NEAR THE COAST THIS AFTN/EVENING ONCE
AGAIN...WITH ONLY 20% POPS AT RIC. FOR NOW, HAVE ADDED VCSH TO
PHF/ORF/ECG TO ACCOUNT FOR THIS, AS COVERAGE WILL LIKELY BE
SLIGHTLY LESS THAN YESTERDAY. BRIEF LIFR VSBYS (DUE TO +RA) ARE
LIKELY IN ANY TSTM.
OUTLOOK: ISOLATED TO SCATTERED AFTERNOON-LATE EVENING TSTMS ARE
EXPECTED THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK, ALONG
WITH THE POTENTIAL FOR EARLY MORNING GROUND FOG/STRATUS.
MARINE
AS OF 230 AM EDT FRIDAY...
KEY MESSAGES:
- BENIGN MARINE CONDITIONS CONTINUE OUTSIDE OF LOCAL
INFLUENCES FROM AFTERNOON AND EVENING STORMS.
- MODERATE RIP CURRENT RISK FOR THE NORTHERN BEACHES TODAY.
SUB-SCA CONDITIONS ARE FORECAST TO PERSIST TODAY INTO THE WEEKEND,
AND LIKELY INTO NEXT WEEK AS WELL. HIGH PRESSURE WELL OFFSHORE AND A
WEAK SURFACE TROUGH WILL ALLOW W AND SW WINDS THIS MORNING TO BECOME
SE 5-10 KT THIS AFTERNOON. THE SURFACE TROUGH TRANSLATES OFFSHORE
THIS WEEKEND WITH FLOW BECOMING ENE OR E SATURDAY AND SUNDAY.
SOUTHERLY FLOW RETURNS NEXT WEEK. WAVES IN THE CHES BAY WILL AVERAGE
1-2 FT THROUGH THE PERIOD WITH SEAS MAINLY 2-3 FT. COVERAGE OF
AFTERNOON AND EVENING SHOWERS AND STORMS WILL BE MORE ISOLATED TODAY
INTO THE WEEKEND AS THE UPPER TROUGH AXIS MOVES INTO THE WESTERN
ATLANTIC. HOWEVER, ANY STORMS THAT DO MANAGE TO FORM WILL CONTINUE
TO POSE LOCALIZED THREATS OF GUSTY WINDS AND FREQUENT LIGHTNING.
THERE IS A MODERATE RIP CURRENT RISK FOR THE NORTHERN BEACHES
(INCLUDING OCEAN CITY) AS SOUTHEASTERN SWELL ENERGY INCREASES TODAY.
THERE IS A LOW RIP RISK FOR THE SOUTHERN BEACHES. ALL BEACHES RETURN
TO LOW RIP RISK SATURDAY AND SUNDAY. UPWELLING ALONG THE NORTHERN NC
OBX HAS ABATED SOMEWHAT WITH WATER TEMPS RISING BACK INTO THE UPPER
60S OVER THE LAST 12-24 HOURS. COOLER THAN NORMAL TEMPERATURES WILL
LIKELY CONTINUE UNTIL FLOW BECOMES ONSHORE THIS WEEKEND.
