Fire Weather Planning Forecast for SW VA...SE WV and NW NC
National Weather Service Blacksburg VA
347 PM EDT Sat Oct 21 2017


...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 in the 30 percent to 40 percent 
range this afternoon will steadily increase to well above 50 percent by 
Monday. Light transport winds and a relatively shallow mixing height 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.

Including the city of Yanceyville
