AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
1208 PM EDT WED JUN 25 2025
SYNOPSIS
THE HEAT WAVE CONTINUES THROUGH THE END OF THE WEEK FOR MUCH OF
THE AREA, BUT EASES UP SLIGHTLY AS THE CHANCE FOR MAINLY
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS INCREASES.
NEAR TERM /THROUGH FRIDAY NIGHT/
AS OF 1207 PM WEDNESDAY...
KEY POINTS:
* EXTREME HEAT WARNINGS AND HEAT ADVISORIES CONTINUE ACROSS THE
LOWLANDS AND SOUTHERN AND LOWER MOUNTAINOUS TERRAIN FOR HEAT
INDEX VALUES IN THE 100S THIS AFTERNOON.
* HEAT ADVISORIES ARE IN EFFECT ACROSS THE LOWLANDS FOR HEAT
INDEX VALUES IN THE 100S THURSDAY AFTERNOON.
* HEAT ADVISORIES ARE IN EFFECT ACROSS THE LOWLANDS FOR HEAT
INDEX VALUES IN THE 100S FRIDAY AFTERNOON.
HIGH PRESSURE AT THE SURFACE AND ALOFT WILL CONTINUE TO PROVIDE
HOT AND HUMID WEATHER CONDITIONS THROUGH THE END OF THE WEEK.
ANOTHER WARM AND MUGGY NIGHT IS ON TAP FOR TONIGHT, PROVIDING
LITTLE RELIEF FROM THE PERSISTENT HEAT. HEAT ADVISORIES AND
WARNINGS CONTINUE IN EFFECT FOR MOST OF THE AREA AS HEAT INDEX
VALUES MEANDER AROUND 103 THIS AFTERNOON. EXTREME HEAT WARNINGS
AND HEAT ADVISORIES HAVE BEEN EXTENDED INTO THURSDAY EVENING FOR
MOST PARTS OF NE KENTUCKY, SE OHIO AND MUCH OF THE LOWLANDS OF
WEST VIRGINIA, AS SIMILAR CONDITIONS ARE EXPECTED.
SIMILAR HOT AND HUMID CONDITIONS ARE ANTICIPATED ON FRIDAY, SO
ANOTHER HEAT ADVISORY HAS BEEN ISSUED FOR ALL OF THE LOWLANDS UNTIL
8 PM FRIDAY EVENING.
WITH ABUNDANT LOW LEVEL MOISTURE (PWATS AROUND 2 INCHES), AFTERNOON
HEAT AND A LACK OF DEEP LAYERED SHEAR OR ANY OTHER UPPER LEVEL
SUPPORT, ISOLATED DIURNAL CONVECTION CAN BE EXPECTED EVERY AFTERNOON
AND EVENING THROUGH FRIDAY. WATER LOADING SOUNDINGS ARE INDICATIVE
OF STRONG DOWNBURST POSSIBLE. WPC KEEPS A MARGINAL RISK FOR
EXCESSIVE RAINFALL AT LEAST FOR SOME PORTIONS OF OUR AREA EVERY DAY
THROUGH FRIDAY.
VERY WARM AND MUGGY NIGHTS WILL CONTINUE, WITH PRECIPITATION
ACTIVITY PROMOTING CHANCES FOR OVERNIGHT FOG DEVELOPMENT WHEREVER
THEY OCCUR.
EXPECT AN INCREASE IN CONVECTIVE COVERAGE EACH DAY AS A FRONTAL
BOUNDARY APPROACHES FROM THE NORTH.
SHORT TERM /SATURDAY THROUGH SUNDAY/
AS OF 1207 PM WEDNESDAY...
WEATHER CHARTS SUGGEST THE FRONT WILL NEVER MAKE IT SOUTH INTO
OUR AREA. INSTEAD, THE FRONTAL BOUNDARY LIFTS NORTH OVER THE
WEEKEND AS THE UPPER LEVEL HIGH DRIFTS EAST OF THE APPALACHIANS
BY FRIDAY NIGHT. THIS WILL ALLOW FOR SOUTHERN STREAM SHORTWAVE
TO LIFT NORTH AND PROVIDE SOME FORCING UNDER A MOIST AND
UNSTABLE ENVIRONMENT. THEREFORE, THE AREA WILL REMAIN UNSETTLED
WITH ADDITIONAL AFTERNOON SHOWERS AND THUNDERSTORMS POSSIBLE
OVER THE WEEKEND.
VERY WARM AND MUGGY NIGHTS WILL CONTINUE, WITH PRECIPITATION
ACTIVITY PROMOTING CHANCES FOR OVERNIGHT FOG DEVELOPMENT WHEREVER
THEY OCCUR.
TEMPERATURES WILL MODERATE SOME, DUE TO CLOUDINESS AND AFTERNOON COOLING
SHOWER.
LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/
AS OF 1207 PM WEDNESDAY...
BETTER CHANCES FOR SHOWERS AND STORMS ARRIVE TUESDAY WITH A COLD
FRONT. DRY WEATHER RETURNS BY MID NEXT WEEK. TEMPERATURES WILL
MODERATE SOME BEHIND THE COLD FRONT BY MID WEEK.
CENTRAL GUIDANCE KEEPS HIGHS AROUND 90 AND LOWS AROUND 70 ACROSS THE
LOWLANDS INTO EARLY NEXT WEEK, BEFORE BOTH TAIL OFF TOWARD NORMAL
HEADING INTO THE MIDDLE OF NEXT WEEK.
AVIATION /16Z WEDNESDAY THROUGH SUNDAY/
AS OF 640 AM WEDNESDAY...
VALLEY FOG WENT OCCASIONALLY IFR ALONG THE OHIO RIVER AND
TYGART VALLEY EARLY THIS MORNING, AND SITES WILL IMPROVE FROM
MVFR TO VFR RIGHT AROUND OR JUST BEFORE THE START OF THE
FORECAST, 12Z.
TODAY BRINGS THE FIRST NOTEWORTHY CHANCE FOR AFTERNOON AND
EVENING THUNDERSTORMS IN SEVERAL DAYS, AT LEAST ACROSS THE
NORTH, AS A WEAK COLD FRONT APPROACHES FROM THAT DIRECTION.
HAVE PROB30 TSRA CODED UP FOR PKB AND CKB 21-24Z.
VALLEY FOG MAY FORM AGAIN LATE TONIGHT, ESPECIALLY AT SITES
IMPACTED BY A THUNDERSTORM LATER TODAY OR THIS EVENING.
SURFACE FLOW WILL BE CALM TO LIGHT AND VARIABLE, BENEATH LIGHT,
MAINLY NORTHWEST FLOW ALOFT.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z THURSDAY...

ALTERNATE SCENARIOS: TIMING AND IMPACTS FROM THUNDERSTORMS MAY
