649 FNUS55 KCYS 211934 FWFCYS Fire Weather Planning Forecast for Southeast Wyoming/Western Nebraska National Weather Service CHEYENNE WY 134 PM MDT Fri Jun 21 2024 .DISCUSSION... Widespread showers and thunderstorms this afternoon with just about every fire weather zone seeing a good chance for wetting rains. Warm front over northeast Carbon County through Albany County into north central Colorado this afternoon. This front will eventually move east through the overnight hours. Much drier Saturday into Sunday across the forecast area as the front moves east into central Nebraska. Drier air will lead to decreasing chances for showers and storms Saturday...but especially Sunday. Afternoon humidity falls into the teens west of the Laramie Range Saturday and spreads east of the Laramie Range Sunday. Given fuels are not reported ready...no fire weather concerns are minimal. Continued warm and mainly dry starting next work week with afternoon humidities becoming critical each afternoon.
