FNUS75 KCYS 150852 FWSCYS Spot Forecast for FE Warren Pile RX...USWFS National Weather Service Cheyenne WY 252 AM MDT Wed Apr 15 2026 If conditions become unrepresentative, contact the National Weather Service at (307) 772-2227 ...FIRE WEATHER WATCH IN EFFECT FROM THURSDAY AFTERNOON THROUGH THURSDAY EVENING... .DISCUSSION... On the heels of the system that impacted the area yesterday, bringing light accumulations, we dry out today with weak high pressure building in. West winds will pick up this morning, gusting up to 45 mph, and then decrease during the afternoon hours. Under clear skies and gusty winds today, this will exacerbate the drying out process. The ridge will remain firmly in place for the first part of Thursday. As winds remain breezy, min RH values tank, bringing elevated fire weather concerns, hence the Fire Weather Watch we have out. By Thursday evening, changes are in store with an approaching cold front. Expect cooler temperature late week and a abundance of precipitation, possibly accumulating snow Friday. .TODAY...
