CHEYENNE, Wyo. — Dry weather is dominating the Cheyenne forecast for the rest of the week. The weather in southeast Wyoming will remain clear, with Wednesday being the warmest day at a high of 87, according to the National Weather Service in Cheyenne.
The NWS in Cheyenne has issued a fire weather watch for parts of southeast Wyoming on Wednesday afternoon. Cheyenne is outside the watch area, but gusty winds and low relative humidity could cause critical fire weather conditions nearby. For those wanting to get the last bit of camping in for the season, outdoor burning is strongly discouraged.
Winds are expected to increase on Wednesday afternoon, with gusts reaching up to 35 mph in areas west of the Interstate 25 corridor. Temperatures in Cheyenne are predicted to climb into the upper 80s on Wednesday, about 5 to 10 degrees warmer than average for late August.
A cold front will sweep through the area Wednesday night, briefly lowering temperatures on Thursday. The cooler air will bring seasonable conditions, with Thursday’s highs staying in the upper 70s to low 80s.
Minimal precipitation is expected through the weekend. Temperatures will rise back into the mid-80s by Friday as a ridge of high pressure builds across the western United States. Light disturbances could bring isolated showers or storms to the high terrain on Sunday and Monday, though the chance of rain remains low.
With dry conditions prevailing, elevated fire weather concerns will persist through the week, especially in areas west of the Laramie Range.
