AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
154 PM EDT SAT JUN 28 2025
SYNOPSIS
DAILY CHANCES FOR SHOWERS AND STORMS PREVAIL THROUGH THE WEEKEND
AMID THE ONGOING HEAT WAVE. COLD FRONTAL PASSAGE TUESDAY. BRIEF
HIGH PRESSURE WEDNESDAY. ANOTHER COLD FRONT CROSSES THURSDAY.
NEAR TERM /THROUGH TONIGHT/
AS OF 135 PM SATURDAY...
A COLD FRONT STALLS TO OUR NORTH THIS EVENING. AN UNSTABLE
ENVIRONMENT, CHARACTERIZED BY PWATS UP TO 2 INCHES, SBCAPE EXCEEDING
3,000 J/KG AND POOR DEEP LAYERED SHEAR WILL SUPPORT DEVELOPMENT FOR
SLOW-MOVING AFTERNOON SHOWERS AND THUNDERSTORMS THROUGH THIS
EVENING. LOCALIZED WATER PROBLEMS MAY RESULT FROM REPETITIVE HEAVY
DOWNPOURS, OR VERY SLOW MOVING STORMS. CONVECTION MAY BE MORE ACTIVE
ACROSS THE NORTHERN PORTIONS OF OUR CWA NEARBY THE FRONT, AND OVER
THE HIGHER ELEVATIONS THIS EVENING. SOME MODELS SHOW FEW RIPPLES OF
VORTICITY WITHIN A ZONAL FLOW AT H500 PASSING TONIGHT. SPC MAINTAINS
A MARGINAL RISK FOR SEVERE THUNDERSTORMS FOR THESE AREAS THROUGH
THIS EVENING. THE MAIN THREAT WILL BE DAMAGING WINDS AND HEAVY
DOWNPOURS.
THERE COULD BE A LULL IN PRECIPITATION ACTIVITY LATE TONIGHT INTO
SUNDAY MORNING. HOWEVER, EXPECT LESS CONVECTIVE ACTIVITY ON SUNDAY.
A CLEAN ZONAL FLOW AT H500 WILL ALLOW FOR ANOTHER EPISODE OF
CONVECTION DRIVEN BY DIURNAL HEATING AND AMPLE MOISTURE DURING THE
AFTERNOON AND EVENING HOURS.
IT WILL REMAIN MUGGY AT NIGHT WITH DEWPOINTS REACHING THE MID 70S
ACROSS THE LOWLANDS. HOT TEMPERATURES IN THE LOWER 90S AND AVAILABLE
MOISTURE WILL PROVIDE HEAT INDEX VALUES IN THE UPPER 90S ACROSS SOME
LOWLAND SPOTS ON SUNDAY AFTERNOON.
SHORT TERM /SUNDAY THROUGH TUESDAY/
AS OF 135 PM SATURDAY...
THE FRONT REMAINS STATIONARY ACROSS OUR NORTH THROUGH SUNDAY NIGHT,
AND THEN RELOCATES JUST NORTHEAST OF OUR CWA BY MONDAY. ITS VICINITY
WILL ENHANCE DIURNAL HEATING CONVECTION MONDAY AFTERNOON AND
EVENING, WHILE A NEW COLD FRONT APPROACHES FROM THE WEST. MODELS
HAVE BEEN CONSISTENT ON THE TIMING OF THIS NEW COLD FRONT, ARRIVING
TO SE OH BY TUESDAY MORNING. CENTRAL GUIDANCE INCREASES POPS TO
CATEGORICAL MONDAY THROUGH TUESDAY. SCATTERED TO NUMEROUS SHOWERS
AND THUNDERSTORMS CAN BE EXPECTED. FLOODING ISSUES MAY BE A CONCERN.
SUNDAY AND MONDAY NIGHTS WILL STILL FEEL LESS MUGGY THAN PREVIOUS
NIGHT WITH TEMPERATURES IN THE UPPER 60S ACROSS THE LOWLANDS,
RANGING INTO THE LOWER 60S NORTHEAST MOUNTAINS. HOT TEMPERATURES
AROUND 90 DEGREES CAN BE EXPECTED MONDAY AFTERNOON ACROSS THE
LOWLANDS. HOWEVER, TEMPERATURES WILL MODERATE ON TUESDAY DUE TO
ABUNDANT CLOUDINESS, COOLING SHOWERS AND A RELATIVELY FRESHER
AIRMASS BEHIND THE COLD FRONT. EXPECT HIGHS IN THE MID 80S ACROSS
THE LOWLANDS, RANGING INTO THE 60S HIGHER ELEVATIONS ON TUESDAY.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
AS OF 135 PM SATURDAY...
SURFACE HIGH PRESSURE BUILDS TUESDAY NIGHT AND WEDNESDAY PROVIDING
DRIER WEATHER CONDITIONS AND A RETURN OF HOT TEMPERATURES.
FORECAST WEATHER CHARTS SHOW ANOTHER COLD FRONT ARRIVING TO OUR AREA
THURSDAY, CROSSING SLOWLY SOUTH INTO EARLY FRIDAY. ALTHOUGH, IT IS
STILL FAR OUT, ACCEPTED GENERAL GUIDANCE WITH SLIGHT CHANCE
PROBABILITY OF PRECIPITATION FOR NOW.
A GRADUAL WARM UP CAN BE EXPECTED WEDNESDAY INTO THE WEEKEND, WITH
TEMPERATURES REACHING THE LOWER 90S BY SATURDAY.
AVIATION /18Z SATURDAY THROUGH THURSDAY/
AS OF 152 PM SATURDAY...
RADAR IMAGERY SHOWS SHOWERS AND THUNDERSTORMS DEVELOPING ALONG
WHAT APPEARS TO BE A SURFACE BOUNDARY EXTENDING FROM PA,
SOUTHWEST TO CENTRAL KY AT THE MOMENT OF WRITING. EXPECT
CONVECTION TO INCREASE IN COVERAGE AND INTENSITY THIS AFTERNOON.
SOME STORMS COULD BE STRONG TO SEVERE, CAPABLE TO PRODUCE VERY
HEAVY DOWNPOURS AND DAMAGING WIND GUSTS. TERMINALS MOST LIKELY
TO BE AFFECTED WILL BE PKB, CKB AND EKN. THIS ACTIVITY WILL LAST
PAST SUNSET, BUT DECREASING IN COVERAGE AND INTENSITY TONIGHT.
OVERALL, EXPECT VFR CONDITIONS UNDER LIGHT FLOW. BRIEF PERIODS
OF IFR/LIFR CONDITIONS WILL RESULT WITH THE HEAVIER SHOWERS OR
STORMS. STRONG GUSTY WINDS MAY ACCOMPANY STRONG STORMS.
A COLD FRONT STALLS TO OUR NORTH THIS EVENING, PERHAPS KEEPING
CHANCES FOR PRECIPITATION INTO THE OVERNIGHT HOURS. NEARBY THE
FRONT, LOW LEVEL STRATUS WILL BE POSSIBLE MAINLY ACROSS THE
NORTHERN SITES (PKB, CKB AND EKN). MVFR/IFR CEILINGS COULD
MATERIALIZE OVER THESE TERMINALS DURING THE OVERNIGHT HOURS.
CALM WINDS TONIGHT, IN CONJUNCTION WITH THE NEARBY FRONT, WILL
POSE A HIGHER LIKELIHOOD FOR RIVER VALLEY FOG LATE TONIGHT INTO
SUNDAY MORNING. THIS WILL ESPECIALLY BE THE CASE FOR LOCATIONS
THAT RECEIVE MEASURABLE RAINFALL WITH ACTIVITY LATER ON TODAY.
IFR/LIFR CONDITIONS POSSIBLE UNDER DENSE FOG MAINLY AFFECTING
EKN. ALTHOUGH OTHER RIVER VALLEYS AND AREAS THAT RECEIVE RAIN
WILL EXPERIENCE FOG, IT MAY REMAIN SHALLOW OR IN THE VICINITY
OVER THE REST OF TERMINALS.
