AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
109 AM EDT SAT SEP 6 2025
SYNOPSIS
A SLOW PROGRESSING COLD FRONT WILL YIELD ONE MORE DAY OF SHOWERS
AND MOUNTAIN THUNDERSTORMS TODAY BEFORE ITS DEPARTURE. HIGH
PRESSURE RETURNS SUNDAY INTO NEXT WEEK.
NEAR TERM /THROUGH TONIGHT/
AS OF 110 AM SATURDAY...
SHOWERS AND EMBEDDED THUNDERSTORMS DRAPED ALONG A COLD FRONT
WILL CONTINUE TO GLIDE UP THROUGH THE FORECAST AREA EARLY THIS
MORNING AS THE BOUNDARY MAKES SLOW EASTWARD PROGRESS THROUGH THE
REGION. CONVECTIVE TRENDS SINCE THE START OF SHIFT HAVE SHOWN
STORMS PETERING OUT AS THEY SAIL THROUGH EASTERN KENTUCKY INTO
THE OHIO RIVER VALLEY. AFTER A FEW INSTANCES OF STRONG WINDS AND
HAIL HERE IN OUR FORECAST AREA THIS PAST EVENING, MAIN CONCERNS
NOW WITH OVERNIGHT STORMS WILL BE THE ONGOING LIGHTNING AND
HEAVIER DOWNPOURS SKIRTING OVERHEAD.
BY DAYBREAK THIS MORNING, THE FRONT IS ANTICIPATED TO BE
VENTURING INTO OUR HIGHER ELEVATION ZONES AS IT CONTINUES ITS
SLOW DEPARTURE TOWARDS THE MID-ATLANTIC REGION. ADDITIONAL
IMPULSES ATTACHED TO THE PARENT UPPER LEVEL TROUGH DRIVING THIS
COLD FRONT WILL ENCOURAGE RAIN TO CONTINUE TODAY FOR THE BULK
OF THE FORECAST AREA, WITH AFTERNOON THUNDERSTORMS DEVELOPING ALONG
AND AHEAD OF THE FRONTAL BOUNDARY. WE SHOULD SEE PRECIPITATION
CHANCES TAPER DOWN QUICKLY FROM WEST TO EAST LATE THIS
AFTERNOON ONCE THE FRONT TREKS EAST OF THE APPALACHIAN
MOUNTAINS. THE SEVERE THREAT FOR OUR AREA WILL BE CAPPED AT A
GENERAL RISK FOR THUNDERSTORMS TODAY, WITH THE BEST INSTABILITY
NOW RESIDING TO OUR EAST.
QUIETER WEATHER BEGINS TO SETTLE BACK INTO THE AREA LATE TONIGHT
AS THE FIRST SIGNS OF HIGH PRESSURE BUILD IN FROM THE NORTHWEST.
LESSENING CHANCES FOR SHOWERS WRAP UP ALONG THE SPINE OF THE
MOUNTAINS OVERNIGHT, LEAVING BEHIND ENOUGH LOW LEVEL MOISTURE IN
THE WAKE OF THE FRONT TO PRODUCE RIVER VALLEY FOG INTO SUNDAY
MORNING.
SHORT TERM /SUNDAY THROUGH TUESDAY/
AS OF 110 AM SATURDAY...
AFTER A SUCCESSION OF COLD FRONTS THAT SWEPT THROUGH THE
CENTRAL APPALACHIANS OVER THE PAST FEW DAYS, SURFACE HIGH
PRESSURE WILL TAKE CENTER STAGE FOR THE END OF THE WEEKEND AND
INTO THE START OF THE NEW WEEK. THIS FEATURE IS SLATED TO DROP
DOWN FROM THE UPPER MIDWEST ON SUNDAY AND PIVOT INTO THE OHIO
VALLEY BY MONDAY. DURING WHICH TIME, ANY LINGERING SHOWER OVER
THE MOUNTAINS WILL PETER OUT SUNDAY MORNING AS DRY AIR FILTERS
DOWN FROM THE NORTHWEST. THIS WILL BEGIN THE MULTI-DAY STRETCH
OF DRY WEATHER PROGGED FOR THE FORECAST AREA THROUGH THE REST OF
THE SHORT AND LONG TERM PERIODS.
WITH THE SURFACE HIGH RESIDING NEARLY OVERHEAD ON SUNDAY NIGHT,
SUFFICIENT RADIATIONAL COOLING MAY YIELD PATCHY FROST TO SPROUT
WITHIN OUR MOUNTAINOUS RIVER VALLEYS HEADING INTO MONDAY
MORNING. OVERNIGHT LOWS IN THESE LOCATIONS ARE ANTICIPATED TO
TOPPLE DOWN INTO THE UPPER 30S, WHILE THE REST OF THE FORECAST
AREA WILL WAKE UP TO LOWS IN THE 40S. THIS COULD ALSO BECOME THE
CASE OVERNIGHT MONDAY INTO TUESDAY FOR THE NORTHEAST WV
MOUNTAINS, BUT BECOMING CONTAINED TO THE HIGHER ZONES OF
SOUTHEAST RANDOLPH AND NORTHWEST POCAHONTAS COUNTIES AS
MODERATING TEMPERATURES BEGIN TO TAKE SHAPE WITH THE ANTICIPATED
REPOSITIONING OF THE SURFACE HIGH. OTHERWISE, DAYTIME
TEMPERATURES DURING THE SHORT TERM PERIOD ARE EXPECTED TO REMAIN
SLIGHTLY BELOW NORMAL IN THE 60S/70S FOR BOTH MONDAY AND TUESDAY
AFTERNOONS.
LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/
AS OF 110 AM SATURDAY...
HIGH PRESSURE REMAINS TRIUMPHANT THROUGH THE MAJORITY OF THE
FORECAST PERIOD, ADVERTISING MOSTLY DRY WEATHER FOR THE WORK
WEEK. THE CENTER OF THIS SURFACE FEATURE BEGINS TO SHIFT
EASTWARD THROUGHOUT THE COURSE OF THE WEEK, ALLOWING FOR A
GRADUAL MODERATION IN TEMPERATURES BACK TOWARDS NORMAL READINGS
FOR THIS TIME OF YEAR. A MOISTURE-STARVED COLD FRONT IS
CURRENTLY ANALYZED TO TRAIL DOWN FROM THE GREAT LAKES REGION
LATE IN THE WORK WEEK, BUT SHOWING NO SIGNS OF ALTERING THE
PREVAILING DRY AND SEASONABLE FORECAST PROJECTED TO ROUND OUT
THE VALID FORECAST PERIOD.
AVIATION /06Z SATURDAY THROUGH WEDNESDAY/
AS OF 1250 AM SATURDAY...
LATE EVENING CONVECTION MOVING IN FROM THE WEST WILL CONTINUE TO
PETER OUT AS WE PROGRESS THROUGH THE OVERNIGHT HOURS.
PRECIPITATION ADVANCING AHEAD OF A COLD FRONT MAY STILL POSE
OVERNIGHT RESTRICTIONS TO CENTRAL AND EASTERN TERMINALS, IN
ADDITION TO POST-FRONTAL STRATUS AND FOG THAT LOOMS INTO THE
MORNING HOURS. DUE TO THE SLOW NATURE OF THIS FROPA, CURRENT
THINKING IS THAT VSBY RESTRICTIONS SET FORTH BY FOG WILL BE SLOW
TO ERODE SATURDAY MORNING, SO HELD ONTO SUB-VFR CONDITIONS
LONGER THAN NORMAL FOR ALL TAF SITES.
THE FRONT IS ANTICIPATED TO BE DRAPED ALONG THE MOUNTAINS BY
DAYBREAK THIS MORNING, AND WILL CONTINUE TO MAKE A SLOW EASTWARD
DEPARTURE THROUGHOUT THE DAY. ADDITIONAL SHOWERS AND AFTERNOON
THUNDERSTORMS WILL GRADUALLY COME TO AN END FROM WEST TO EAST
TODAY AS HIGH PRESSURE KNOCKS ON OUR DOOR FOR LATE TONIGHT INTO
SUNDAY. ANOTHER DECENT SIGNATURE OF RIVER VALLEY FOG WAS NOTED
FOR OVERNIGHT TONIGHT, AND IS HINTED AT WITHIN THE LATEST
FORECAST PACKAGE.
LIGHT WINDS OUT OF THE WEST/SOUTHWEST IS ANTICIPATED THROUGHOUT
THE PERIOD.
