FIRE WEATHER PLANNING FORECAST FOR SW VA...SE WV AND NW NC
NATIONAL WEATHER SERVICE BLACKSBURG VA
529 AM EDT MON MAR 30 2015

.DISCUSSION...
RADAR INDICATES LIGHT RAIN/SNOW ACROSS THE MOUNTAINS THIS MORNING AS A 
COLD FRONT APPROACHES FROM THE WEST. BESIDES PRODUCING A FEW HUNDREDTHS 
OF WETTING PRECIPITATION...DEWPOINTS/RH VALUES ARE RISING AS THE 
PRECIPITATION MOISTENS THE ATMOSPHERE. THE COLD FRONT WILL PASS ACROSS 
THE AREA DURING LATE MORNING...RESULTING IN A WEST NORTHWEST WIND SHIFT.
THIS DOWNSLOPE FLOW WILL CAUSE DEWPOINTS/RH TO FALL AGAIN HEADING INTO 
THE AFTERNOON...WITH CLEARING SKIES ALLOWING SUNSHINE TO ADD TO THE 
HEATING. WHILE FUEL MOISTURES ARE MODESTLY RESPONDING TO THE PRECIPITATION 
THIS MORNING...EXPECT FUEL MOISTURES TO DECREASE AGAIN AS DRYING TAKES PLACE 
THIS AFTERNOON.

TUESDAY APPEARS TO BE MORE CRITICAL AS A STRONG LOW PRESSURE SYSTEM PASSES 
EASTWARD ACROSS THE SOUTHERN GREAT LAKES. SOUTHWESTERLY WIND FLOW WILL 
SUPPORT EVEN WARMER TEMPERATURES...RESULTING IN RH VALUES BETWEEN 20 AND 
25 PERCENT AREAWIDE. WINDS GUSTS OF 25 TO 30 MPH WILL BE COMMON ACROSS 
MUCH OF THE AREA...WITH OCCASIONAL GUSTS AS HIGH AS 40 MPH. THESE 
CONDITIONS WILL HAVE A STRONG DRYING AFFECT ON FUELS.
