AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
155 AM EDT FRI JUN 27 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 CONTINUES.
NEAR TERM /THROUGH TODAY/
AS OF 8:30 PM THURSDAY...
MAIN CHANGE WAS TO UPDATE THE POPS TO REFLECT SOME HIGHER POPS
OVER CENTRAL AND SOUTHERN PARTS OF THE CWA OVER THE NEXT SEVERAL
HOURS, AND ALSO PUT IN SOME GUSTY WIND AND HEAVY RAIN WORDING
FOR THE WEATHER GRIDS THROUGH 04Z/MIDNIGHT. OTHERWISE, NO MAJOR
CHANGES WERE MADE.
AS OF 130 PM THURSDAY...
WEATHER PATTERN HAS NOT CHANGE MUCH DURING THE PAST FEW DAYS UNDER
AN INFLUENCE OF A DOME OF HIGH PRESSURE AT THE SURFACE AND AT THE
UPPER LEVELS. ENVIRONMENT CHARACTERIZED BY HIGH CAPE, HIGH PWATS,
AND LOW SHEAR MAY BE CONDUCIVE TO SEVERE DOWNBURSTS THROUGH
THIS EVENING. SPC MAINTAINS A MARGINAL RISK FOR SEVERE STORMS AS
AFTERNOON CONVECTION WILL GRADUALLY DISSIPATE THIS EVENING. THE
MAIN THREAT WILL BE DAMAGING WINDS AND HEAVY DOWNPOURS.
ANOTHER MUGGY NIGHT IS EXPECTED WITH LOWS GENERALLY IN THE LOWER 70S
LOWLANDS, RANGING INTO THE MID 70S NORTHEAST MOUNTAINS. A
RENEGADE SHOWER OR TWO, OR A STORM MAY BE POSSIBLE TONIGHT, SO
KEPT SLIGHT CHANCE POPS FOR THIS ACTIVITY THROUGH THE OVERNIGHT
HOURS. PATCHY VALLEY FOG MAY ONCE AGAIN DEVELOP ESPECIALLY OVER
AREAS THAT RECEIVE RAIN.
WITH SIMILAR ENVIRONMENTAL PARAMETERS, EXPECT SIMILAR CONVECTIVE
DEVELOPMENT FRIDAY AFTERNOON AND EVENING, PERHAPS MORE CONCENTRATED
ACROSS THE MOUNTAINS. HOT TEMPERATURES ON FRIDAY WILL REACH THE LOW
TO MID 90S ACROSS THE LOWLANDS, RANGING INTO THE MID 70S NORTHEAST
MOUNTAINS. WITH DEWPOINTS IN THE LOWER 70S EXPECTED, HEAT INDEX
VALUES WILL LIKELY REACH OR EXCEED THE 100 DEGREE MARK ACROSS
THE LOWLANDS. THEREFORE, WILL MAINTAIN A HEAT ADVISORY FOR THESE
AREAS FRIDAY THROUGH FRIDAY EVENING.
THE UPPER LEVEL HIGH/RIDGE SLIDES EAST OF THE APPALACHIANS
FRIDAY NIGHT WEAKENING ITS INFLUENCE OVER OUR AREA. THIS COULD
MAINTAIN SHOWERS AND STORM ACTIVITY GOING FRIDAY NIGHT.
ANOTHER WARM AND MUGGY NIGHT IS ON TAP FRIDAY NIGHT, PROVIDING
LITTLE RELIEF FROM THE HEAT, ESPECIALLY FOR THOSE WITHOUT THE
BENEFIT OF AIR CONDITIONING.
SHORT TERM /TONIGHT THROUGH 6 PM SATURDAY/
AS OF 130 PM THURSDAY...
ON SATURDAY, CONVECTIVE PARAMETERS WILL STILL BE PRESENT WITH HIGH
CAPE, POOR DEEP LAYERED SHEAR AND HIGH PWATS. THE INCREASINGLY
UNSTABLE CONDITIONS WILL ADD TO A PASSING SHORTWAVE ON SATURDAY,
ENHANCING CONVECTION TO STRONG TO SEVERE. SPC KEEPS THE ENTIRE AREA
UNDER A MARGINAL RISK FOR SEVERE STORMS.
SHOWERS AND STORMS WILL BE LESS INTENSE SATURDAY NIGHT AND SUNDAY,
MAINLY NEARBY A FRONTAL BOUNDARY EXPECTED TO STALL NORTH OF THE
AREA. A BRIEF SURFACE HIGH PRESSURE EMERGES AS THE FRONT LIFTS NORTH
MONDAY. HOWEVER, MODELS SUGGEST DIURNAL CONVECTION STILL POSSIBLE.
WPC HAS A MARGINAL RISK FOR EXCESSIVE RAINFALL FOR THE ENTIRE AREA
FOR MONDAY.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
AS OF 130 PM THURSDAY...
MODELS BRING A COLD FRONT CROSSING EARLY TUESDAY WITH SHOWERS
AND THUNDERSTORMS LIKELY. A HIGH PRESSURE BUILDS BEHIND THE
FRONT, PROMOTING DRIER AND COOLER WEATHER BY THE MIDDLE OF NEXT
WEEK. CENTRAL GUIDANCE KEEPS HIGHS AROUND 90 AND LOWS AROUND 70
ACROSS THE LOWLANDS BY MONDAY, BEFORE BOTH TAIL OFF TOWARD
NORMAL HEADING INTO THE MIDDLE OF NEXT WEEK.
AVIATION /06Z FRIDAY THROUGH TUESDAY/
AS OF 155 AM FRIDAY...
LATE NIGHT SHOWERS AND STORMS HAVE BEGUN TO DIMINISH AT THE TIME
OF WRITING AND SHIFTING INTO NORTH-CENTRAL WEST VIRGINIA. AS THE
OVERNIGHT HOURS MARCH ON, POTENTIAL FOR FOG WILL INCREASE,
ESPECIALLY AT TERMINALS THAT RECEIVED PRECIPITATION EARLIER THIS
EVENING. OSCILLATING SURFACE VSBYS AND CEILINGS WILL CONTINUE
UNTIL DAYBREAK. ANOTHER HOT AND MUGGY DAY WILL YIELD POTENTIAL
FOR AFTERNOON CONVECTION ACROSS THE CENTRAL APPALACHIANS ONCE
MORE. WINDS WILL REMAIN GENERALLY LIGHT THROUGH THE VALID TAF
PERIOD OUTSIDE OF ANY SHOWER OR STORM PROGGED FOR FRIDAY
AFTERNOON AND EVENING.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SATURDAY...
FORECAST CONFIDENCE: MEDIUM.
ALTERNATE SCENARIOS: FOG FORMATION TIMING AND EXTENT MAY VARY
DEPENDING ON CLOUD COVER AND RECENT RAINS.
