High pressure will continue to bring dry weather to the Appalachians and central mid Atlantic region into the first part of the weekend. Minimum relative humidity values will generally be at or above 40 percent, but some lower values into the 30s will be found across Southside VA and also in the valleys west of the Blue Ridge. Winds will be light but good mixing during the afternoon will aid smoke dispersion. A cold front will move into the region from the west on Saturday, then likely stall across southeast Virginia into northern North Carolina. The front will bring a low chance of showers to areas west of the Blue Ridge Saturday and mainly south and east of the Blue Ridge Sunday into Monday. Rainfall amounts are expected to be mostly 1/4 inch or less through the period. For the specific location of the wildfire, look for minimum relative humidity values today of 35 to 40 percent with afternoon maximum temperatures in the 78 to 82 degree range. No rainfall is expected today. Winds will continue to be mostly northeast to north around 5 mph, but with high pressure overhead, may tend to become light and variable in direction. .TODAY...
