DISCUSSION
A WARM FRONT WILL LIFT ACROSS THE AREA TONIGHT AS HIGH PRESSURE
MOVES OFFSHORE. THIS WILL LEAD TO INCREASING CLOUDS AND MILDER
TEMPERATURES, WITH A FEW SHOWERS APPROACHING WESTERN MARYLAND BY
DAYBREAK ON WEDNESDAY.
A COLD FRONT APPROACHING FROM PENNSYLVANIA WILL DROP INTO THE
MID-ATLANTIC THROUGH WEDNESDAY NIGHT. SCATTERED TO NUMEROUS
SHOWERS AND A FEW THUNDERSTORMS ARE POSSIBLE DURING THIS TIME.
THE FRONT WILL REMAIN STALLED NEARBY THURSDAY WITH A POP UP SHOWER
POSSIBLE AROUND THE SHENANDOAH VALLEY THURSDAY AFTERNOON.
THE FRONT WILL LIFT BACK NORTHWARD AS A WARM FRONT FRIDAY INTO
SATURDAY, THEN WILL BE FOLLOWED BY A COLD FRONT SATURDAY NIGHT.
HIGH PRESSURE WILL LIKELY RETURN SUNDAY INTO MONDAY.
RH WILL RECOVER TO 55 TO 75 PERCENT TONIGHT, AND WILL LIKELY
CONTINUE RISING ACROSS THE ALLEGHENIES WEDNESDAY WHILE HOLDING
STEADY ELSEWHERE. RH MAY DROP IN AROUND 40 PERCENT SOUTH OF I-64
WEDNESDAY AFTERNOON. WINDS WILL LIKELY GUST 20 TO 30 MPH AS THEY
SHIFT TO OUT OF THE WEST ALONG AND WEST OF I-81 AND NEAR AND SOUTH
OF I-64 WEDNESDAY AFTERNOON. GIVEN THE DOWNSLOPING FLOW, RH COULD
DROP MORE THAN FORECAST IN THE I-64 CORRIDOR (TO NEAR 30 PERCENT)
RESULTING IN A LOCALLY ELEVATED FIRE WEATHER THREAT IN THOSE AREAS.
