AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
805 PM EDT FRI MAR 28 2025
SYNOPSIS
A WARM FRONT EXITED NORTH OF THE AREA THIS EVENING. WARMER
WEATHER AHEAD. THUNDERSTORMS EXPECTED SUNDAY AND MONDAY. A FEW
COULD BE STRONG TO SEVERE. COLD FRONTAL PASSAGE MONDAY.
NEAR TERM /THROUGH SATURDAY/
AS OF 800 PM FRIDAY...
LIGHT SHOWERS EXITED NORTHEAST AS A WARM FRONT LIFTED NORTH OF
THE AREA EARLY THIS EVENING. THE AREA REMAINS UNDER A WARM
SECTOR OF AN APPROACHING COLD FRONT. MOIST AND WARM ADVECTION
COULD PRODUCE CLOUDS ACCOMPANIED BY VIRGA FROM TIME TO TIME
TONIGHT. WINDS WILL INCREASE AS THE PRESSURE GRADIENT TIGHTENS
UP ON SATURDAY.
ADJUSTED HOURLY TEMPERATURES AND DEWPOINTS TO BETTER MATCH
LATEST SURFACE OBSERVATIONS. OTHERWISE, CURRENT FORECAST
REMAINS ON TRACK.
AS OF 305 PM FRIDAY...
A WARM FRONT LIFTING NORTH OF THE AREA THIS AFTERNOON WILL TAKE
THE SHOWERS AND THUNDERSTORMS WITH IT BY LATE AFTERNOON. THE
STRONGER STORMS HAVE PRODUCE PEA-SIZED HAIL. FARTHER SOUTH, AN
ISOLATED SHOWER OR THUNDERSTORM STILL CANNOT BE RULED OUT IN THE
UNSTABLE AIR SOUTH OF THE WARM FRONT AMID A DEEP INVERTED-V
SOUNDING.
SOUTH OF THE FRONT, MUCH OF THE AREA HAS BROKEN OUT INTO
SUNSHINE, A GUSTY SOUTHWEST WIND, LOWLAND TEMPERATURES UP AROUND
80, AND RELATIVE HUMIDITY VALUES IN THE 25 TO 35 PERCENT RANGE.
IN COORDINATION WITH STATE AGENCIES AND NEIGHBORING OFFICES,
HAVE ISSUED A FIRE DANGER STATEMENT FOR THIS AFTERNOON AND
EVENING AS FUEL MOISTURE RESIDES IN THE 7 TO 8 PERCENT RANGE.
STACKED HIGH PRESSURE OFF THE SOUTHEAST COAST, AND A DAMPENING
FLAT LOW PRESSURE WAVE TRACKING EAST ACROSS THE MIDWEST AND
GREAT LAKES, WILL MAINTAIN A STRONG SOUTHWEST FLOW OF
UNSEASONABLY MILD AIR ACROSS THE AREA TONIGHT INTO SATURDAY.
THIS FLOW MAY DIMINISH LATER SATURDAY AFTERNOON AS THE FLAT WAVE
GOES BY AND WEAKENS FURTHER. NONETHELESS, MAY NEED ANOTHER FIRE
DANGER STATEMENT SATURDAY FOR SIMILAR WIND GUSTS AND MINIMUM
RELATIVE HUMIDITY VALUES, ALONG WITH THE DRY FUELS.
LOW LEVEL FLOW WILL RESULT IN SOMEWHAT OF A RIDGE/VALLEY
TEMPERATURE SPLIT ON LOWS TONIGHT, WHILE A CANOPY OF MID/HIGH
CLOUD LIMIT THE DIURNAL RANGE IN THIS UNSEASONABLY WARM REGIME.
SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/
AS OF 200 PM FRIDAY...
SUNDAY STARTS OFF WITH A TROUGH ACROSS THE CENTRAL U.S., AND A
STRENGTHENING SURFACE LOW MOVING INTO THE GREAT LAKES REGION, WITH A
COLD FRONT THAT WILL EVENTUALLY SWEEP EAST ACROSS THE CWA ON MONDAY.
AS WE PROGRESS INTO THE LATE AFTERNOON/EVENING HOURS ON SUNDAY,
INSTABILITY WILL BE ON THE INCREASE PARTICULARLY TO OUR WEST/ALONG
WESTERN ZONES OUT AHEAD OF THE FRONT. THERE STILL REMAINS SOME
UNCERTAINTY IN THE CONVECTIVE ACTIVITY IN OUR AREA DURING THIS
PERIOD, AS SHOWERS AND STORMS ARE EXPECTED EARLIER IN THE DAY FROM A
PASSING WAVE, AND THIS MAY HINDER SOME DEVELOPMENT LATER ON IN THE
DAY. IN ADDITION, INSTABILITY WILL BE WANING SOMEWHAT AS WE GO INTO
THE OVERNIGHT HOURS, HOWEVER, STRONG TO SEVERE STORMS CANNOT BE
RULED OUT ACROSS WESTERN ZONES SUNDAY EVENING/NIGHT, WITH DAMAGING
WINDS THE PRIMARY HAZARD DUE TO THE OVERALL STRONG DYNAMICS/DEEP
STRONG SHEAR ASSOCIATED WITH THE SYSTEM. AT THIS POINT, SPC IS
MAINTAINING A SLIGHT RISK FOR SEVERE WEATHER LATE SUNDAY THROUGH
EARLY MONDAY MAINLY ACROSS THE WESTERN HALF OF THE CWA.
AS THE COLD FRONT PROGRESSES EASTWARD ON MONDAY, THERE WILL STILL BE
A RISK FOR SEVERE STORMS, BUT IT REMAINS UNCERTAIN, AS COLD FRONT
AND BULK OF CONVECTION SHOULD GENERALLY BE EXITING TO THE EAST BY
THE LATE MORNING/EARLY AFTERNOON. HOWEVER, SPC CONTINUES TO KEEP
MUCH OF THE AREA HIGHLIGHTED FOR A SEVERE RISK THIS DAY AT THIS
POINT DUE TO UNCERTAINTY.
ANY STORMS THAT DO DEVELOP WILL CONTAIN HEAVY DOWNPOURS, WITH HIGH
MOISTURE CONTENT AIR TRANSPORTED TO THE REGION.
LONG TERM /TUESDAY THROUGH FRIDAY/
AS OF 200 PM FRIDAY...
COLD FRONT TO THE EAST OF THE AREA ON TUESDAY, WITH DRIER CONDITIONS
TAKING HOLD BEHIND THE FRONT AS HIGH PRESSURE BUILDS IN FROM THE
NORTH. THE DRY SPELL LOOKS TO BE SHORT LIVED HOWEVER AS ANOTHER
SYSTEM AFFECTS THE AREA MID WEEK, WITH SHOWERS AND POTENTIAL
THUNDERSTORMS AGAIN, ALONG WITH THE POTENTIAL FOR A SOAKING
RAIN.
AVIATION /00Z SATURDAY THROUGH WEDNESDAY/
AS OF 754 PM FRIDAY...
SURFACE HIGH PRESSURE, OFF THE MID ATLANTIC COAST, EXTENDS WEST
ACROSS OUR AREA TO PROVIDE MOSTLY DRY WEATHER CONDITIONS
TONIGHT. THE AREA WILL REMAIN UNDER INCREASING SOUTHWEST FLOW
AHEAD OF AN APPROACHING COLD FRONT. THIS FLOW WILL BRING MOIST
AND WARM AIR ADVECTION, DESTABILIZING THE ATMOSPHERE TO PRODUCE
MAINLY SHOWERS.
A FEW WEAK SHORTWAVES, MORE EVIDENT AT H700 LEVEL, WILL ARRIVE
FROM THE WEST AROUND 10-12Z SATURDAY MORNING, SPREADING
SCATTERED LIGHT SHOWERS. NOT THE BEST TIME FOR THESE FEATURES
TO PRODUCE THUNDERSTORMS. THEREFORE, KEPT THUNDER OUT OF TAFS
FOR NOW DURING THE MORNING HOURS. AFTERNOON HEATING COULD
CONTRIBUTE FOR STRONGER CONVECTION ACROSS WV SATURDAY AFTERNOON
AND EVENING.
WINDS WILL QUICKLY DIMINISH THIS EVENING, BECOMING LIGHT AND
VARIABLE, OR EVEN CALM TONIGHT. SURFACE GUSTY WINDS ARE
EXPECTED TO INCREASE 20 TO 25 KT ON SATURDAY. IN ADDITION,
MODERATE SOUTHWEST FLOW ALOFT IS LIKELY TO RESULT IN LOW LEVEL
WIND SHEAR OVERNIGHT TONIGHT INTO SATURDAY MORNING, UNTIL
SURFACE GUSTS RESUME.
