AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
651 AM EDT WED JUL 2 2025
SYNOPSIS
MAINLY DRY WITH LESS MUGGY CONDITIONS TODAY. INCREASINGLY HOT
HEADING INTO THE HOLIDAY WEEKEND WITH MINIMAL PRECIPITATION
CHANCES UNTIL EARLY NEXT WEEK.
NEAR TERM /THROUGH TONIGHT/
AS OF 225 AM WEDNESDAY...
WITH CLEARING SKIES, LIGHT WINDS, AND AMPLE LOW LEVEL MOISTURE FROM
EARLIER PRECIPITATION, FOG WAS FORMING ACROSS THE REGION THIS
MORNING. EXPECT THIS TO CONTINUE INTO DAYBREAK WITH SOME LOCALLY
DENSE FOG POSSIBLE, ESPECIALLY IN VALLEY LOCATIONS - HAVE ISSUED AN
SPS FOR FOGGY CONDITIONS FOR THE MORNING COMMUTE.
SUBSIDENCE ALOFT ASSOCIATED WITH THE EASTERN LIMB OF SPRAWLING HIGH
PRESSURE CENTERED OVER THE LOWER MISSISSIPPI VALLEY SHOULD SERVE TO
SUPPRESS ANY ADDITIONAL DIURNAL SHOWERY ACTIVITY OVER THE LOWLANDS
TODAY, BUT COULDN'T COMPLETELY RULE OUT AN AFTERNOON SHOWER OR
THUNDERSTORM OVER THE HIGHER TERRAIN WHERE PARCELS MAY BE ABLE TO
LOCALLY OVERCOME THE SUBSIDENCE INVERSION VIA ELEVATED HEAT SOURCE.
WHILE IT WILL FEEL A LITTLE LESS HUMID WITH THE AIRMASS CHANGE,
STRONG EVAPOTRANSPIRATION ONCE WE BREAK OUT TO FULL SUNSHINE TODAY
WILL LIKELY KEEP DEW POINTS IN THE MID TO UPPER 60S.
WITH MOIST GROUND CONDITIONS AGAIN TONIGHT, EXPECT VALLEY FOG
TO FORM AGAIN FAIRLY EARLY IN THE OVERNIGHT, ALTHOUGH SOME
MIXING OUT MAY BE POSSIBLE ACROSS THE NORTH HEADING INTO THE
MORNING COMMUTE AS GRADIENTS BEGIN TO TIGHTEN AS HIGH PRESSURE
BEGINS TO BE SUPPRESSED SOUTHWARD.
SHORT TERM /THURSDAY THROUGH SATURDAY NIGHT/
AS OF 225 AM WEDNESDAY...
QUIET CONDITIONS ARE EXPECTED HEADING INTO THE HOLIDAY WEEKEND WITH
A WEAK AND LIKELY DRY BACKDOOR COLD FRONT EXPECTED DURING THE DAY
THURSDAY. THIS WILL YIELD ANOTHER SHOT OF SLIGHTLY DRIER AIR FOR THE
4TH AND SATURDAY. CENTRAL GUIDANCE HAS A STRONG WARM-UP WITH DAYTIME
HIGHS ACROSS THE LOWER ELEVATIONS RISING BACK INTO THE UPPER 80S FOR
THE 4TH AND LOW 90S BY SATURDAY. GIVEN THE MOIST GROUND CONDITIONS,
THIS MAY BE A LITTLE AMBITIOUS WITH THE LACK OF STRONG WARM
ADVECTION.
LONG TERM /SUNDAY THROUGH TUESDAY/
AS OF 225 AM WEDNESDAY...
GLOBAL MODELS DIFFER ON HOW QUICKLY RIDGING BREAKS DOWN SUNDAY INTO
MONDAY IN ADVANCE OF AN APPROACHING COLD FRONT ON THE RELATIVELY LOW
AMPLITUDE NORTHERN STREAM, WITH CENTRAL GUIDANCE LARGELY HOLDING OFF
ANY SIGNIFICANT PRECIPITATION CHANCES UNTIL MONDAY. DESPITE HIGH
TEMPERATURES REMAINING IN THE UPPER 80S TO MID 90S, AFTERNOON MIXED
DEW POINTS GENERALLY 70 DEGREES OR LESS SHOULD KEEP INDICES BELOW
HEAT ADVISORY CRITERIA.
AVIATION /12Z WEDNESDAY THROUGH SUNDAY/
AS OF 605 AM WEDNESDAY...
CLEARING SKIES IN THE WAKE OF AN EXITING COLD FRONT HAS ALLOWED
FOG AND LOW STRATUS TO FORM ACROSS MUCH OF THE AREA THIS
MORNING. CONDITIONS ARE EXPECTED TO IMPROVE BY 13-14Z THIS
MORNING WITH A DIURNAL CUMULUS FIELD DEVELOPING BY EARLY
AFTERNOON. WHILE AN ISOLATED SHOWER CANNOT BE RULED OUT CLOSER
TO THE HIGHER TERRAIN THIS AFTERNOON, WILL KEEP ANY VCSH OR SHRA
OUT OF THE BKW/EKN TAFS FOR NOW GIVEN LIMITED CHANCES FOR
TERMINAL IMPACTS.
AT LEAST PATCHY VALLEY FOG IS EXPECTED TO FORM AGAIN TONIGHT,
ALTHOUGH TIGHTENING GRADIENTS ACROSS THE NORTH HEADING INTO
DAYBREAK MAY ALLOW FOR SOME IMPROVEMENT PRIOR TO SUNRISE.
WINDS REMAIN LIGHT FAVORING A NORTHWESTERLY DIRECTION.
AS OF 1000Z COMM LINES APPEAR TO BE DOWN AT HTS AND PKB FOR
AUTOMATED OBSERVATION TRANSMISSION - CURRENT OBSERVATIONS ARE
AVAILABLE VIA RADIO AND PHONE ATIS.
