AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
334 AM EDT WED JUN 25 2025
SYNOPSIS
A LARGE RIDGE REMAINS ACROSS THE EASTERN CONUS, BRINGING VERY HOT
CONDITIONS TO THE REGION THROUGH THE WEEK. LOW- END CHANCES FOR
AFTERNOON SHOWERS AND THUNDERSTORMS MAKE A RETURN FROM MID WEEK INTO
THE WEEKEND.
NEAR TERM /UNTIL 6 AM THIS MORNING/
AS OF 255 AM EDT WEDNESDAY...
- EXTREME HEAT WARNINGS REMAIN IN EFFECT EVERYWHERE, EXCLUDING THE
MARYLAND BEACHES WEDNESDAY.
- A FEW ISOLATED TO SCATTERED STORMS ARE POSSIBLE WEDNESDAY
AFTERNOON AND EVENING. A FEW STORMS MAY BE STRONG TO SEVERE.
EARLY THIS MORNING, THE EXPANSIVE ~596 DM UPPER RIDGE REMAINS
CENTERED JUST TO THE WEST OF THE FORECAST AREA. MEANWHILE AT THE
SURFACE, ~1022 MB HIGH PRESSURE IS CENTERED NEAR SOUTHWEST VIRGINIA.
A WEAK FRONTAL BOUNDARY IS LOCATED ON THE NORTHERN PERIPHERY OF THE
RIDGE NEAR THE SOUTHERN GREAT LAKES. ANOTHER MORNING WITH VERY WARM
TEMPERATURES WITH READINGS IN THE LOWER 80S ACROSS THE URBAN AREAS
AND ALONG THE COAST, WITH MID TO UPPER 70S ELSEWHERE. CANNOT RULE
OUT A (VERY) ISOLATED SHOWER OR THUNDERSTORM EARLY THIS MORNING, BUT
THE MAJORITY OF THE AREA STAYS DRY.
THE UPPER RIDGE REMAINS WITH US TODAY, BUT HEIGHTS DECREASE SLIGHTLY
(2-3 DM). THE WEAKENING OF THE RIDGE WILL ALSO ALLOW FOR 700 MB
TEMPS TO COOL (~9 TO 10 C), WEAKENING THE CAP OVER THE AREA COMPARED
TO THE PAST FEW DAYS. IN ADDITION, A 250 MB JET STREAK DEVELOPS
SOUTH OF THE AREA OVER THE CAROLINAS TODAY. THE COMBINATION OF THE
HOT TEMPERATURES/HIGH INSTABILITY, THE WEAKENING OF THE RIDGE, AND
THE 250 MB JET STREAK WILL LIKELY ALLOW FOR MORE SCATTERED AFTERNOON
AND EVENING THUNDERSTORMS COMPARED TO WHAT WE HAVE SEEN. GIVEN THE
HIGH INSTABILITY, ANY STRONGER STORMS WILL HAVE THE POTENTIAL TO
PRODUCE DAMAGING WIND GUSTS. SPC HAS THE AREA IN A MARGINAL RISK (1
OF 5) FOR SEVERE THUNDERSTORMS TODAY, WITH A SLIGHT RISK (2 OF 5)
LINGERING JUST TO OUR SW OVER THE CAROLINAS. TEMPERATURE-WISE, HIGHS
TODAY WILL BE FAIRLY SIMILAR TO YESTERDAY (UPPER 90S TO AROUND
100). THE HEAT COMBINED WITH DEWPOINTS IN THE LOW TO MID 70S
(LOCALLY UPPER 70S), WILL RESULT IN ANOTHER DAY WITH HEAT INDICES
OF 105 TO 110+. EXTREME HEAT WARNINGS REMAIN IN EFFECT FOR ALL AREAS
OUTSIDE OF THE MD BEACHES WHERE A HEAT ADVISORY IS IN EFFECT.
AFTERNOON STORMS MAY BRING SOME LOCALIZED "RELIEF" FROM THE HEAT.
ANY THUNDERSTORMS COME TO AN END BY ~MIDNIGHT (POSSIBLY LINGERING
LATER ACROSS THE MD EASTERN SHORE). LOWS WILL DROP BACK INTO THE LOW
TO MID 70S, WITH SOME UPPER 70S POSSIBLE CLOSER TO THE COAST.
SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY NIGHT/
AS OF 330 AM EDT WEDNESDAY...
KEY MESSAGES:
- HEAT ADVISORIES WILL LIKELY BE NEEDED FOR MUCH OF THE AREA ON
THURSDAY.
- SCATTERED SHOWERS AND THUNDERSTORMS DEVELOP ON THURSDAY AND FRIDAY
AFTERNOONS, WITH MORE COVERAGE THAN PREVIOUS DAYS. A FEW STORMS
COULD BE STRONG TO SEVERE.
AS THE UPPER RIDGE CONTINUES TO GRADUALLY WEAKEN THURSDAY,
TEMPERATURES WILL ALSO "COOL" TO THE LOW TO MID 90S (LOCALLY UPPER
90S). HEAT INDICES WILL ALSO DECREASE SLIGHTLY, RUNNING AROUND 105-
108 FOR MOST OF THE AREA, WITH MUCH OF THE EASTERN SHORE LIKELY LESS
THAN 105. HEAT ADVISORIES WILL LIKELY BE NEEDED FOR MUCH OF THE AREA
OUTSIDE OF THE EASTERN SHORE. SCATTERED AFTERNOON/EVENING
THUNDERSTORMS ARE EXPECTED, WITH EVEN HIGHER COVERAGE COMPARED TO
WEDNESDAY AS A FRONTAL BOUNDARY DROPS CLOSER TO THE LOCAL AREA.
SIMILAR TO WEDNESDAY, A FEW STORMS AGAIN HAVE THE POTENTIAL TO BE
STRONG TO SEVERE AND PRODUCE DAMAGING WIND GUSTS DUE TO CONTINUED
HIGH INSTABILITY OVER THE REGION. SPC HAS MAINTAINED A MARGINAL RISK
(1 OF 5) FOR SEVERE THUNDERSTORMS ON THURSDAY. IN ADDITION, LOCALLY
HEAVY RAINFALL WILL BE POSSIBLE AS WELL, WITH WPC PLACING ALL BUT
THE SOUTHEAST IN A MARGINAL RISK FOR EXCESSIVE RAINFALL. LOWS
THURSDAY NIGHT IN THE LOW TO MID 70S ARE EXPECTED.
BY FRIDAY, EXPECT THE BOUNDARY THAT WILL BE LINGERING TO OUR NORTH
TO SLIP INTO FAR NORTHEASTERN PORTIONS OF THE AREA IN A BACKDOOR
FASHION. THIS WILL RESULT IN SLIGHTLY COOLER TEMPERATURES,
ESPECIALLY ACROSS THE EASTERN SHORE AND NORTHERN PORTIONS OF THE
AREAS WHERE HIGHS STAY IN THE 80S. ELSEWHERE, HIGHS WILL GENERALLY
BE IN THE LOWER 90S. WE MAY SEE A FEW SPOTS (MAINLY SE) APPROACH 105
DEGREE HEAT INDICES, BUT AM NOT ANTICIPATING ANY HEAT ADVISORIES AT
THIS TIME. SCATTERED TO POTENTIALLY MORE NUMEROUS SHOWERS/STORMS
ACROSS THE NW DEVELOP FRIDAY AFTERNOON, WITH FRIDAY LIKELY HAVING
THE MOST ACTIVITY OF THE WEEK. SIMILAR TO THE PAST COUPLE OF DAYS,
STRONG WIND GUSTS OR LOCALLY HEAVY RAINFALL CANNOT BE RULED OUT WITH
THE STRONGEST STORMS.
LONG TERM /SATURDAY THROUGH TUESDAY/
AS OF 330 AM EDT WEDNESDAY...
KEY MESSAGES:
- HOT WEATHER CONTINUES INTO EARLY NEXT WEEK.
- AN UNSETTLED PATTERN DEVELOPS WITH DAILY, DIURNAL CHANCES FOR
SCATTERED STORMS.
THE FRONT THAT DROPPED INTO NORTHEASTERN PORTIONS OF THE AREA FRIDAY
LIFTS BACK TO THE NORTH ON SATURDAY. THE UPPER RIDGE REMAINS WITH US
THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK, THOUGH NOT AS STRONG
AS WHAT WE SAW EARLIER THIS WEEK. TEMPERATURES WILL REMAIN ABOVE
AVERAGE THROUGHOUT THE PERIOD WITH HIGHS GENERALLY IN THE LOW
TO MID 90S. MAX HEAT INDEX VALUES WILL RANGE FROM 100 TO 105
THIS WEEKEND INTO EARLY NEXT WEEKEND AND HEAT ADVISORIES MAY BE
NEEDED FOR A FEW SPOTS AS THE FORECAST IS FINE TUNED. SCATTERED
AFTERNOON/EVENING THUNDERSTORMS WILL BE COMMON THROUGHOUT THE
PERIOD, WITH THE BEST COVERAGE EACH DAY ACROSS THE NW. PWATS
INCREASE TO 2.0"+ FOR MUCH OF THE AREA LATER THIS WEEKEND INTO
EARLY NEXT WEEK, WHICH WILL RESULT IN A HEAVY RAIN THREAT.
AVIATION /08Z WEDNESDAY THROUGH SUNDAY/
AS OF 137 AM EDT WEDNESDAY...
VFR CONDITIONS WILL PREVAIL THROUGH THE TAF PERIOD AT ALL TERMINALS.
WHILE SOME ISOLATED CONVECTION IS POSSIBLE TOMORROW AFTERNOON
THROUGH TOMORROW NIGHT, CONFIDENCE IN TIMING AND LOCATION IS TOO LOW
TO INCLUDE IN THE TAFS FOR NOW. SURFACE WINDS WILL REMAIN LIGHT
THROUGH TOMORROW, WITH A VARIABLE WIND DIRECTION FAVORED FOR MOST OF
TODAY AND TONIGHT. SPOTTY MVFR VIS IS POSSIBLE (ESPECIALLY TOWARDS
SUNRISE), BUT COVERAGE IS EXPECTED TO BE LIMITED.
OUTLOOK: OTHERWISE, PREVAILING VFR THROUGH THE END OF THE WEEK INTO
THE WEEKEND AS HIGH PRESSURE REMAINS OVER THE REGION. LATE
AFTN/EVENING SHOWERS/TSTMS ARE POSSIBLE THU-SUN (HIGHEST CHC INLAND)
AS THE UPPER LEVEL RIDGE GRADUALLY WEAKENS.
MARINE
AS OF 255 PM EDT TUESDAY...
KEY MESSAGES:
- BENIGN MARINE CONDITIONS CONTINUE THROUGH THE END OF THE WEEK.
BENIGN MARINE CONDITIONS WILL CONTINUE THROUGH THE EXTENDED FORECAST
AS HIGH PRESSURE REMAINS DOMINANT ACROSS THE REGION. THE WIND
DIRECTION WILL BE INFLUENCED BY THE SEA BREEZE DURING THE DAY AS THE
LAND HEATS UP, THEN WILL BECOME GENERALLY VARIABLE OVERNIGHT. AS THE
HIGH STARTS TO SHIFT OFFSHORE BY MID-LATE WEEK AND INTO THE WEEKEND,
WINDS WILL SETTLE ON A S/SW WIND DIRECTION, THOUGH SEA BREEZES WILL
STILL IMPACT AREAS CLOSE TO SHORE. THE PRESSURE GRADIENT MAY TIGHTEN
MARGINALLY THURSDAY THROUGH THE WEEKEND AND A FEW GUSTS TO 20 KT ARE
POSSIBLE LATER FRIDAY AND SATURDAY. HOWEVER, WIDESPREAD SCAS APPEAR
UNLIKELY AT THIS TIME. ISOLATED TO SCATTERED STORMS ARE ALSO
POSSIBLE IN THE AFTERNOONS AND EVENINGS WEDNESDAY THROUGH THE
WEEKEND. SEAS IN THE OCEAN REMAIN AROUND 2 FT FOR THE WEEK,
INCREASING TO 2-3 FT BY FRIDAY AND SATURDAY. WAVES IN THE
CHESAPEAKE BAY AND RIVERS OF 1-2 FT OR LESS THROUGH THE PERIOD.
