ALLEGHENIES.
IN THE WAKE OF A COLD FRONT EXITING TO THE SOUTHEAST THROUGH
THIS MORNING, COOLER TEMPERATURES ARE EXPECTED TODAY AND
TOMORROW. HIGH TEMPERATURES TODAY RISE INTO THE 60S FOR MOST
WITH HIGHER ELEVATIONS STAYING IN THE 50S. TONIGHT, OVERNIGHT
LOWS DROP INTO THE 30S AND 40S. FROST AND/OR FREEZE CONDITIONS
ARE POSSIBLE FOR THOSE ALONG THE ALLEGHENIES AS TEMPERATURES
DROP INTO THE LOW TO MID 30S. MINIMAL CLOUD COVER OVERNIGHT
COMBINED WITH LIGHTER WINDS YIELD CONDITIONS FAVORABLE FOR
RADIATIONAL COOLING. CURRENTLY, BEST CHANCES FOR FROST/FREEZE
IS IN HIGHLAND COUNTY VA AND PENDLETON COUNTY WV WHERE
TEMPERATURES WILL BE THE COOLEST.
TEMPERATURES INCREASE SLIGHTLY ON FRIDAY WITH SURFACE HIGH
PRESSURE OVERHEAD. HIGH TEMPERATURES WILL BE IN THE 60S TO LOW
70S WITH THE ALLEGHENIES STAYING IN THE 50S. OVERNIGHT LOWS WILL
BE IN THE 40S AND 50S. CLOUD COVER INCREASES OVERNIGHT AS A

KEY MESSAGE 2...MILDER FOR THE WEEKEND WITH INCREASING RAIN

HEIGHT RISES WILL COMMENCE ON SATURDAY AS A STUBBORN UPPER-LEVEL LOW
CHURNING NEAR JAMES BAY WEAKENS SLIGHTLY. AT THE SURFACE, A COLD
FRONT WILL APPROACH THE UPPER OHIO RIVER VALLEY WHILE WEAKENING.
HIGH PRESSURE OFFSHORE WILL RESULT IN MODEST RETURN FLOW AND MILDER
TEMPERATURES, WITH A FEW SHOWERS OR THUNDERSTORM POSSIBLE SATURDAY.
BY SUNDAY, A SHORTWAVE WILL DIVE DOWN THE REAR FLANK OF THE TROUGH
TOWARD THE GREAT LAKES/MIDWEST. THIS WILL DRIVE A STRONGER COLD
FRONT FROM THE OHIO RIVER VALLEY TO THE EAST COAST. A SECONDARY WAVE
OF LOW PRESSURE IS LIKELY TO DEVELOP AS THE FRONT CROSSES THE MID-
ATLANTIC, THOUGH IT REMAINS TO BE SEEN IF THIS ENHANCES RAINFALL
LOCALLY OR CAUSES IT TO "SKIP" OVER THE REGION AS MANY SYSTEMS OF
DONE RECENTLY.
IN THE WAKE OF THE LATE WEEKEND FRONT, COOLER THAN NORMAL WEATHER IS
SET TO RETURN FOR THE FIRST HALF OF NEXT WEEK. RAIN CHANCES MAY
LINGER INTO MONDAY MORNING BEFORE DEPARTING AS A COLD FRONT SWINGS
OFFSHORE. WITH HIGH PRESSURE BUILDING IN FROM THE WEST MONDAY NIGHT
INTO TUESDAY, OVERNIGHT LOW TEMPERATURES COULD FEASIBLY DROP INTO
THE MID 30S RESULTING IN SOME FROST POTENTIAL FOR THE ALLEGHENIES
HEADING INTO EARLY TUESDAY MORNING.
AS THE HIGH DRIFTS OFFSHORE, THE THREAT OF A FEW POP UP SHOWERS OR
THUNDERSTORMS MAY RE-EMERGE BY THE MIDDLE OF NEXT WEEK.
