Fire Weather Planning Forecast for SW VA...SE WV and NW NC
National Weather Service Blacksburg VA
336 PM EDT Sat Mar 17 2018


A warm front will lift northeast into parts of the area this
evening before shifting back south as a cold front behind a 
passing wave of low pressure overnight. Showers and storms with 
these features may bring heavier rainfall to mainly southern and 
western sections where a half inch of wetting rainfall could 
occur. Otherwise looking at less rainfall across northeast 
sections where only spotty added amounts appear likely overnight. 

The front pushes south of the region with drier weather under
light winds Sunday into Monday morning.

Another system resulting in more widespread wetting rainfall will
impact us by Monday into Tuesday, with colder air and potential 
wintry precipitation returning by the middle of next week.

Including the cities of Roanoke and Salem
