Fire Weather Planning Forecast for Southeast Wyoming/Western Nebraska
National Weather Service Cheyenne WY
200 AM MDT Fri Aug 18 2017

.DISCUSSION...
Sunny and dry today with afternoon humidity west of the Laramie
Range falling to near 15 percent. More widespread low humidity
expected Saturday with slightly gusty winds and warmer
temperatures. Elevated fire weather concerns Saturday with
afternoon humidity dropping to the low teens out west and north
and wind gusts to 25 MPH at times. For now, will hold off on any
fire weather headlines, but if forecast winds get any stronger,
may need to issue something. Cooler temperatures and better
humidity Sunday as a front moves in from the north Sunday
afternoon.
