DISCUSSION
A DRY COLD FRONT WILL MOVE THROUGH TODAY, WITH GUSTY WINDS
DEVELOPING IN ITS WAKE THROUGH THE AFTERNOON. CONDITIONS WILL BE
VERY DRY, WITH MINIMUM RH VALUES AROUND 10-20 PERCENT ACROSS THE
SHENANDOAH VALLEY AND CENTRAL VIRGINIA. FURTHER NORTH, MINIMUM RH
VALUES OF 20-40 PERCENT ARE FORECAST ACROSS NORTHERN VIRGINIA, THE
WEST VIRGINIA PANHANDLE, AND MARYLAND. WINDS WILL GUST TO AROUND 15-
30 MPH THIS AFTERNOON OUT OF THE WEST TO NORTHWEST. NORMALLY THIS
COMBINATION OF DRY AIR AND WINDY CONDITIONS WOULD RAISE FIRE WEATHER
CONCERNS. HOWEVER, MUCH OF THE REGION RECEIVED A SOAKING RAINFALL
THREE DAYS AGO, WITH MANY LOCATIONS RECEIVING A HALF OF AN INCH TO
AN INCH OF RAIN. HIGH CLOUD COVER AND THE LOW SUN ANGLE WILL ALSO
HELP TO LIMIT THE FIRE WEATHER THREAT. WINDS WILL DECREASE OVERNIGHT
AS HIGH PRESSURE BUILDS TOWARD THE AREA FROM THE OHIO VALLEY. RH
VALUES ARE FORECAST TO REBOUND TO AROUND 60-90 PERCENT OVERNIGHT.
HIGH PRESSURE WILL BRIEFLY MOVE OVERHEAD MONDAY. A LOW PRESSURE
SYSTEM MOVING THROUGH THE GREAT LAKES MAY BRING SOME LIGHT
PRECIPITATION LATE MONDAY NIGHT INTO TUESDAY. ANOTHER TRANSIENT AREA
OF HIGH PRESSURE ON WEDNESDAY MAY GIVE WAY TO A WARM FRONT ON
THURSDAY.
