Fire Weather Planning Forecast for SW VA...UPDATED

.DISCUSSION...

...Dry weather tonight into Sunday to give way to widespread
rainfall early next week... 

High pressure will control our weather tonight into Sunday. A strong 
cold front will approach Sunday night and then cross the region 
Monday through Tuesday, bringing good coverage of showers and some 
gusty winds. High pressure returns to the area by the latter half of 
the upcoming week.

Minimum relative humidity values will steadily increase to well above 
50 percent by Monday. Light transport winds and a relatively shallow 
mixing heights will create poor dispersion and ventilation conditions 
into Sunday, but improving conditions are expected as winds increase 
ahead of the approaching cold front. Rainfall amounts of one half inch 
east of the Blue Ridge to two inches in the mountains are possible from 
early Monday into Tuesday.
