AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
256 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 THURSDAY NIGHT/
AS OF 310 PM EDT TUESDAY...
KEY MESSAGES:
- 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.
BY THU, TEMPS "COOL" TO THE LOW-MID 90S (MOST IN THE MID 90S) FOR
HIGHS WITH HEAT INDICES AROUND 105-108F. THE EASTERN SHORE WILL BE A
BIT COOLER WITH HEAT INDICES AROUND 100F. AS SUCH, HEAT ADVISORIES
ARE LIKELY FOR AT LEAST A PORTION OF THE AREA WITH CURRENT GUIDANCE
SUGGESTING EVERYWHERE EXCEPT THE EASTERN SHORE. SCATTERED
AFTERNOON/EVENING STORMS WILL AGAIN BE POSSIBLE WITH 30-60% POPS
(HIGHEST ACROSS THE NW PORTION OF THE FA). A FEW STRONG TO SEVERE
STORMS ARE POSSIBLE GIVEN THE HIGH CAPE/DCAPE ENVIRONMENT. SPC
HAS MAINTAINED A MARGINAL (LEVEL 1/5) RISK FOR A FEW DAMAGING
WIND GUSTS ACROSS MOST OF THE AREA. LOWS THU NIGHT IN THE LOW-
MID 70S ARE EXPECTED.
LONG TERM /FRIDAY THROUGH TUESDAY/
AS OF 310 PM EDT TUESDAY...
KEY MESSAGES:
- HOT WEATHER CONTINUES INTO EARLY NEXT WEEK.
- AN UNSETTLED PATTERN DEVELOPS WITH DAILY, DIURNAL CHANCES FOR
ISOLATED TO SCATTERED STORMS.
ALOFT, THE RIDGE REMAINS OVER THE AREA, BUT TOO A LESSER AMPLITUDE
THAN WHAT WE ARE CURRENTLY EXPERIENCING. AT THE SURFACE, HIGH
PRESSURE REMAINS CENTERED TO THE W OF THE LOCAL AREA. THIS WILL
RESULT IN A FAIRLY STAGNANT, SUMMER PATTERN WITH DAILY HIGHS IN THE
LOW-MID 90S (MOST IN THE MID 90S) AND DAILY HEAT INDICES OF 100-
105F. IN GENERAL, MOST OF THESE DAYS LOOK TO BE BELOW HEAT ADVISORY
CRITERIA (AT LEAST ON A WIDESPREAD LEVEL). WILL NOTE THAT A BRIEF
BACKDOOR COLD FRONT MAY MOVE INTO THE NORTHERN PORTION OF THE AREA
ON FRI, ALLOWING FOR HIGHS IN THE 80S ACROSS THE EASTERN SHORE.
OTHERWISE, ISOLATED TO SCATTERED STORMS ARE POSSIBLE EACH DAY WITH
POPS OF 30-60% FRI, SUN, MON, AND TUE. THE LOWEST CHANCE OF RAIN
APPEARS TO BE SAT WITH 15-35% POPS. A FEW STRONG GUSTS ARE POSSIBLE
WITH ANY STORMS.
AVIATION /07Z 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.
