Fire Weather Planning Forecast for SW VA...SE WV and NW NC
National Weather Service Blacksburg VA
853 PM EDT Wed Oct 18 2017


...Dry weather expected to continue through the weekend...

A large area of high pressure will remain over the eastern part
of the country before slowly sliding off the coast this weekend. 
This will bring us pleasant fall weather through the weekend. Our
chances for rain will then start to increase on Monday as a 
strong cold front approaches from the west.

Minimum relative humidity values will be near 30 percent through
the end of the week before moisture starts to increase over the 
weekend. Light transport winds and a relatively shallow mixing height
will create poor dispersion and ventilation conditions through Friday.

Including the city of Floyd
