Fire Weather Planning Forecast for Southeast Wyoming/Western Nebraska
National Weather Service Cheyenne WY
311 AM MDT Fri Oct 20 2017

.DISCUSSION...

It will be unseasonably warm for one more day today with dry
weather as well. Conditions may get close to critical levels this
afternoon over the plains due to some breezy winds but it appears
humidities will stay generally above critical levels. A strong
cold front will sweep across the districts this evening bringing
windy conditions along with much cooler temperatures for Saturday.
Not much precipitation expected other than a couple inches of snow
possible over the higher mountains tonight. A period of strong
winds looks a good bet around the mountains Sunday night into
Monday.
