DISCUSSION
A FEW SHOWERS ARE ALREADY ONGOING ACROSS SHENANDOAH NATIONAL PARK.
EXPECT ADDITIONAL SHOWERS AND THUNDERSTORMS TO MOVE ACROSS THE PARK
THROUGH THIS EVENING. THE MOST LIKELY TIME FOR THE HEAVIEST SHOWER
AND STORMS IS BETWEEN 7 PM TO 10 PM, WITH ADDITIONAL THUNDERSTORMS
LINGERING THROUGH 1 AM TO 2 AM. STRONG WIND GUSTS OF 50-60 MPH,
TORRENTIAL DOWNPOURS LEADING TO FLOODING, AND LIGHTNING STRIKES
ARE THE MAIN THREATS. GENERALLY LOOKING AT AROUND A HALF INCH TO
ONE INCH OF RAIN, PERHAPS EVEN HIGHER IN HEAVIER BANDS OF RAIN AND
STORMS.
A COLD FRONT WILL PUSH THROUGH THE AREA TONIGHT. HIGH PRESSURE
MOVES OVER THE AREA SUNDAY INTO EARLY NEXT WEEK, BRINGING A COOL
DOWN AND LESS HUMIDITY.
MONDAY AND TUESDAY COULD BE THE DRIEST DAYS IN TERMS OF RH THAT WE
HAVE SEEN IN QUITE SOME TIME. VALLEY LOCATIONS, AS WELL AS THE VA
PIEDMONT COULD EVEN DROP WELL INTO THE 30S. CURRENT FORECAST
SHOWS HIGHER VALUES AT THIS TIME, BUT MAY NEED TO ADJUST AS
CONFIDENCE GROWS. WINDS WILL BE GUSTING OUT OF THE NW AROUND 15 TO
20 MPH EACH AFTERNOON.
