Fire Weather Planning Forecast for SW VA...SE WV and NW NC

.DISCUSSION...
Unusually warm and dry conditions will take place with record 
heat possible by the middle of this week. Rainfall appears 
minimal as any chances of showers or thunderstorms remain 
limited to southeast West Virginia. Otherwise, drought 
conditions will worsen as minimum relative humidity values fall 
towards 25 to 35 percent each afternoon. Some of the southern 
facing slopes may have minimum relative humidity values drop to 
20 percent with afternoon sunshine and gusty winds due to an 
unstable atmosphere from the increasing heat.

These aforementioned conditions will escalate fire danger 
across the entire region. The anomalous heat and low humidity 
combined with daytime gusts could possibly spark new fire 
activity that may spread rapidly. After today, we appear to 
enter a considerable stretch of time where prescribed fire will 
be discouraged as any available resources may need to shift 
towards wildfire suppression.
