AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
220 AM EST MON DEC 16 2024
SYNOPSIS
MORE RAIN MONDAY AND MONDAY NIGHT AS A WEAK COLD FRONT CROSSES
THE AREA. DRY TUESDAY, MORE ACTIVE BY MIDWEEK WITH WINTRY
PRECIPITATION CLOSING OUT THE WEEK. VERY COLD THIS WEEKEND.
NEAR TERM /THROUGH TONIGHT/
AS OF 115 AM SUNDAY...
ANOTHER BAND OF RAIN WILL PUSH NORTHWARD ACROSS THE AREA TODAY
AS A COLD FRONT APPROACHES FROM THE WEST. TEMPERATURES WILL BE
WARM ENOUGH FOR THIS TO BE ALL LIQUID PRECIPITATION. WITH A GOOD
SOUTHERLY TO SOUTHWESTERLY WIND TODAY, PORTIONS OF SOUTHERN
WEST VIRGINIA AND NORTHEASTERN KENTUCKY COULD BE SOUTH OF THE
RAIN BY LATE AFTERNOON, ALLOWING TEMPERATURES TO HIT 60 DEGREES.
A WEAK COLD FRONT WILL THEN PUSH THROUGH THE REGION TONIGHT,
BRINGING ADDITIONAL SHOWERS. FOR BOTH TODAY AND TONIGHT, MOST
AREAS CAN EXPECT BETWEEN A QUARTER AND THREE QUARTERS OF AN
INCH OF RAIN. THE COLD FRONT IS WEAK ENOUGH THAT TEMPERATURES
SHOULD REMAIN ABOVE FREEZING TONIGHT FOR ALL AREAS.
SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/
AS OF 220 AM MONDAY...
TUESDAY SHOWCASES MOSTLY DRY AND MILD WEATHER WITH ZONAL FLOW ABOVE
HIGH PRESSURE IN THE WAKE OF A COLD FRONT. CLOUD COVER WILL DIMINISH
THROUGHOUT THE DAY WITH SOUTHWESTERLY FLOW TAKING OVER. HIGH
TEMPERATURES WILL BE IN THE 50S ACROSS THE LOWLANDS WITH 40S TO MID
50S IN THE MOUNTAINS.
LONG TERM /WEDNESDAY THROUGH SUNDAY/
AS OF 220 AM MONDAY...
RAIN AND MAYBE A FEW MOUNTAIN SNOW SHOWERS WILL RETURN ON WEDNESDAY
WITH A WARM FRONT AND LOW PRESSURE TO OUR SOUTHWEST. RAIN COULD BE
HEAVY AT TIMES WITH QPF OUTPUT SUGGESTING BETWEEN 0.50" AND 1.00" OF
RAINFALL ACROSS PORTIONS OF THE LOWLANDS AND THE MOUNTAINS DURING
THE DAY WEDNESDAY. WEDNESDAY'S TEMPERATURES WILL DEPEND ON
POSITIONING OF THE WARM FRONT, BUT LOCATIONS ACROSS THE SOUTHERN
HALF THE FORECAST AREA COULD SEE TEMPERATURES IN THE UPPER 50S
AND LOWER 60S. LOCATIONS FARTHER NORTH IN OHIO OR ACROSS THE
MOUNTAINS COULD STAY IN THE 40S TO LOWER 50S.
A COLD FRONT FROM THE WEST MOVES THROUGH LATE WEDNESDAY INTO
THURSDAY. THIS FRONT IS SLATED TO BRING SOME COLDER TEMPERATURES
BACK TO THE AREA AND A CHANGE OVER FROM RAIN TO SNOW WILL BE
DEPENDENT ON THE TIMING OF THIS FRONT. NONETHELESS, EXPECTING THE
MOUNTAINS TO SEE SOME UPSLOPE SNOW SHOWERS OR RAIN/SNOW MIX LATE
WEDNESDAY INTO THURSDAY MORNING. LIGHT ACCUMULATIONS ARE POSSIBLE
DEPENDING ON HOW FAST THE CHANGE OVER OCCURS.
HIGH PRESSURE THEN MOVES IN BY THURSDAY AFTERNOON TO DRY US OUT.
SKIES WILL STILL BE PARTLY TO MOSTLY CLOUDY IN THE AFTERNOON WITH
NNW FLOW. WILL HAVE TO WATCH FOR POST FRONTAL LAKE-EFFECT MOISTURE
OCCURRING ACROSS THE LOWLANDS AS MODELS HAVE NOT BEEN BEST ON
PICKING UP ON THIS FEATURE BEHIND COLD FRONTS AS OF LATE. AT
THIS POINT THOUGH, FLOW LOOKS TO BE LIGHT ENOUGH TO KEEP A
STRONG FETCH FROM OCCURRING. THURSDAY'S HIGHS WILL BE IN THE
UPPER 30S AND LOWER 40S ACROSS THE LOWLANDS WITH 20S AND 30S IN
THE MOUNTAINS.
ANOTHER SYSTEM LOOKS TO APPROACH FROM THE WEST FRIDAY MORNING
WITH TEMPERATURES REMAINING COLD ENOUGH TO CREATE A WINTRY MESS.
SNOW OR FREEZING RAIN COULD BE A POSSIBILITY FRIDAY MORNING AND
EVENING WITH COLD TEMPERATURES. MODELS ARE ALL IN AGREEMENT
WITH A FRIDAY MORNING ARRIVAL WITH THE EURO BEING THE QUICKEST
TO PULL IT OUT AND THE CANADIAN BEING A BIT SLOWER. WILL MENTION
SOMETHING IN THE HWO ABOUT THE POSSIBILITY FOR WINTER WEATHER
ACROSS THE AREA.
TEMPERATURES BEHIND THIS SYSTEM LOOK TO BE VERY COLD WITH HIGHS
IN THE 20S AND 30S ACROSS THE AREA ON SATURDAY AND SUNDAY. LOWS
LOOK TO BE IN THE TEENS AND SINGLE DIGITS.
AVIATION /07Z MONDAY THROUGH FRIDAY/
AS OF 1245 AM MONDAY...
GENERALLY MVFR CLOUDS CAN BE EXPECTED EARLY THIS MORNING, WITH
THE EXCEPTION OF THE SOUTHEAST UPSLOPE AREAS AND SOUTHEAST OHIO
WHERE SOME IFR CLOUDS CAN BE EXPECTED.
ADDITIONAL RAIN WILL MOVE THROUGH THE AREA ON MONDAY, CAUSING
MVFR TO IFR CONDITIONS. THIS WILL BE FOLLOWED BY A COLD FRONT
MONDAY NIGHT, BRINGING ADDITIONAL RESTRICTIONS.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z TUESDAY...
FORECAST CONFIDENCE: MEDIUM.
ALTERNATE SCENARIOS: IFR CONDITIONS COULD CREEP INTO OTHER PORTIONS
OF THE AREA THIS MORNING, MORE LIKELY IN NORTHEAST KENTUCKY AND
