AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
830 PM EDT MON MAR 31 2025
SYNOPSIS
A COLD FRONT EXITS TO THE EAST OVERNIGHT BRINGING AN END TO THE
RAIN FOR MOST AS HIGH PRESSURE MOVES IN. LOOKING UNSETTLED
WEDNESDAY THROUGH NEXT WEEKEND.
NEAR TERM /THROUGH TUESDAY/
AS OF 826 PM MONDAY...
SHOWERS AND DRIZZLE PERSIST ACROSS THE MOUNTAINS AND PORTIONS OF
THE LOWLANDS THIS EVENING AS A COLD FRONT TRUDGES EASTWARD.
THIS ACTIVITY WILL SUBSIDE FOR MOST IN THE NEXT FEW HOURS, BUT
SOME LINGERING UPSLOPE DRIZZLE OR LIGHT RAIN SHOWERS ARE
POSSIBLE ACROSS THE HIGHEST ELEVATIONS OF THE MOUNTAINS.
THERE IS THE POSSIBILITY FOR SOME SNOW FLAKES MIXING IN ACROSS
SKI COUNTRY WITH NO ACCUMULATIONS EXPECTED. LOW CLOUDS HOWEVER
WILL REMAIN ACROSS THE MOUNTAINS AND FOOTHILLS OVERNIGHT. SOME
VISIBILITY RESTRICTIONS ARE POSSIBLE ACROSS THESE AREAS TOO WITH
LOWER CEILINGS, MIST/DRIZZLE AND TEMPERATURES DROPPING INTO THE
30S.
BREEZY TO GUSTY NW WINDS ARE BEING REPORTED BEHIND THIS FRONT AT
MULTIPLE ASOS/AWOS SITES. WINDS WILL GRADUALLY SUBSIDE LATER
TONIGHT THOUGH AS HIGH PRESSURE BUILDS IN FROM THE NW.
AS OF 220 PM MONDAY...
SHOWERS ARE STARTING TO SPROUT OVER WESTERN AND CENTRAL WV
ROUGHLY AS EXPECTED, AND THIS ACTIVITY WILL MOVE GENERALLY
NORTHEASTWARD WHILE THE OVERALL SYSTEM SLIDES EASTWARD THROUGH
THE AFTERNOON AND EVENING HOURS. TEMPERATURES ARE UPPER 60S TO
LOWER 70S OVER THE SOUTHERN COALFIELDS, WITH LOW TO MID-70S IN
THE GREENBRIER VALLEY, SO THERE MAY BE JUST ENOUGH FUEL FOR SOME
CONVECTIVE ACTIVITY TO DEVELOP. SOME OF THE HI-RES GUIDANCE
DOES HAVE 500-1000 J/KG OF CAPE IN OUR EASTER AREAS, SO WE'LL
NEED TO BE MONITORING FOR THUNDERSTORMS THIS AFTERNOON AND
EVENING.
ACTIVITY QUICKLY QUIETS DOWN LATER THIS EVENING, THOUGH SOME
MOUNTAIN SHOWERS LIKELY LINGER OVERNIGHT. THE DRY AIR AND
ENCROACHING HIGH PRESSURE WIN BY TUESDAY MORNING, AND CLOUDS
WILL DIMINISH THROUGH THE DAY, WITH A MOSTLY SUNNY AFTERNOON
EXPECTED. LOWS TONIGHT WILL RANGE FROM THE UPPER 20S IN THE
NORTHERN MOUNTAINS TO AROUND 40 DEGREES ACROSS THE SOUTHERN
COALFIELDS AND HUNTINGTON TRI-STATE AREA. ANY LINGERING SHOWERS
IN THOSE NORTHERN MOUNTAINS COULD END AS A BIT OF NON-
ACCUMULATING SNOW. WE'LL BE A BIT COOLER TOMORROW BEHIND THE
FRONT, WITH HIGHS RANGING FROM AROUND 50 DEGREES ON THE HIGHER
RIDGES TO THE LOWER 60S IN THE SOUTHWEST PART OF THE CWA.
SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/
AS OF 250 PM MONDAY...
FIRST PART OF WEDNESDAY SHOULD REMAIN GENERALLY DRY, HOWEVER, A WARM
FRONTAL BOUNDARY WILL BE LIFTING NORTH THROUGH THE AREA, AS LOW
PRESSURE MOVES NORTHEAST INTO THE UPPER MIDWEST/GREAT LAKES REGION.
THIS WILL CREATE A CHANCE FOR SHOWERS AND STORMS BY THE
AFTERNOON/EVENING HOURS AS INSTABILITY INCREASES THROUGH THE DAY. IN
ADDITION, WINDS WILL BE ON THE INCREASE ON WEDNESDAY, AS PRESSURE
GRADIENT TIGHTENS ACROSS THE AREA, AND STRONGER WINDS ALOFT HAVE THE
POTENTIAL TO MIX DOWNWARD. SOME STORMS IN THE WEDNESDAY/WEDNESDAY
NIGHT TIME FRAME COULD BE SEVERE, MAINLY ACROSS WESTERN ZONES, WITH
A CONTINUED THREAT FOR SEVERE ON THURSDAY AS THE COLD FRONT
APPROACHES. BOTH DAYS WILL SEE A THREAT FOR DAMAGING WINDS AND
PERHAPS AN ISOLATED TORNADO THREAT. IN ADDITION, HEAVY DOWNPOURS CAN
BE EXPECTED WITH ANY STORMS AND LOCALIZED FLOODING WILL BE A THREAT.
WITH THE BOUNDARY CONTINUING TO LINGER ACROSS THE AREA DURING BOTH
THE SHORT AND LONG TERM PERIODS, ELECTED TO HOIST A FLOOD WATCH
ACROSS MID OHIO VALLEY REGION DURING THIS TIME PERIOD, EXTENDING
INTO THE LONG TERM.
LONG TERM /FRIDAY THROUGH MONDAY/
AS OF 250 PM MONDAY...
AFOREMENTIONED FRONTAL BOUNDARY WILL STALL OUT NEAR THE OHIO RIVER
VICINITY, AND MEANDER SLIGHTLY FRIDAY INTO THE WEEKEND, WITH
ADDITIONAL WAVES MOVING ALONG THE FRONT TOWARDS THE AREA, BRINGING A
RENEWED THREAT FOR SHOWERS/STORMS, AND HEAVY DOWNPOURS, PARTICULARLY
LATER THURSDAY INTO THE WEEKEND AS STRONG WINDS ALOFT CONTINUE TO
PUMP ANOMALOUSLY HIGH MOISTURE CONTENT AIR INTO THE REGION. AT LEAST
MINOR FLOODING IS ANTICIPATED ALONG SOME MAIN STEM RIVERS, AND
FLOODING LOOKS TO BE LIKELY ALONG AREA CREEKS AND STREAMS,
PARTICULARLY IN THE OHIO VALLEY REGION. DRIER WEATHER DOESN'T LOOK
TO TAKE HOLD UNTIL LATER SUNDAY INTO MONDAY WHEN AN UPPER SHORTWAVE
TROUGH FINALLY IS ABLE TO KICK THINGS OFF TO THE EAST.
AVIATION /01Z TUESDAY THROUGH SATURDAY/
AS OF 745 PM MONDAY...
MVFR AND IFR CONDITIONS WILL CONTINUE WITH LOW CLOUDS AND
RAIN/DRIZZLE ACROSS THE AREA FROM A SLOW MOVING COLD FRONT. IFR
OR LOWER IS EXPECTED ACROSS THE MOUNTAINS TONIGHT AND EVEN
POSSIBLE FOR CKB AND CRW. RAIN SHOWERS AND DRIZZLE WILL LIKELY
BE WRAPPING UP BY ~06-08Z, BUT IT IS LIKELY SOME SHOWERS MAY
STILL REMAIN LONGER ACROSS THE HIGHEST ELEVATIONS IN THE
MOUNTAINS. MVFR AND IFR VIS RESTRICTIONS LIKELY OVERNIGHT WITH
LOW CLOUDS AND RAIN.
LOW CLOUDS WILL START SCATTERING AND LIFTING BY MID TO LATE
TUESDAY MORNING WITH VFR RETURNING IN THE AFTERNOON.
NW'RLY WINDS WILL BE LIGHT TO BREEZY TONIGHT WITH SOME GUSTS
BETWEEN 15 AND 25 KTS POSSIBLE. SOME LOCATIONS ACROSS THE
MOUNTAINS MAY GUST HIGHER. EXPECTING WIND GUSTS TO SLACK OFF
LATER TONIGHT AS THE FRONT EXITS EAST. WINDS ON TUESDAY WILL BE
LIGHT AND PREDOMINANTLY N TO NNE.
