CHEYENNE, Wyo. — Friday is shaping up to be a pleasant day in Cheyenne and across southeast Wyoming, with temperatures slightly cooler than Thursday but still ranging from the upper 70s to mid-80s. According to the National Weather Service in Cheyenne, skies will remain mostly sunny, making for an enjoyable start to the weekend. A weak cold front moving south from Montana into northern Wyoming overnight has helped drop temperatures by around 10 degrees compared to Thursday.
Despite the brief cooldown, the weekend will see a return of unseasonably warm conditions. Highs on Saturday are forecast to rise into the 80s for much of southeast Wyoming, while western Nebraska could see temperatures climb into the 90s. Skies will remain mostly sunny through Saturday, with only scattered clouds arriving by Sunday. Light breezes will move in, but there is minimal chance of precipitation across the region.
However, these dry and warm conditions bring elevated fire risks. The NWS in Cheyenne has noted that fire weather concerns will intensify on Sunday, with winds increasing and relative humidity levels dropping into the teens. This combination of low humidity and strong winds could result in critical fire weather conditions across parts of southeast Wyoming, including Cheyenne, as well as the Nebraska Panhandle.
Sunday is the most likely day for red flag conditions to reach Cheyenne. Winds and dry air will combine with warmer-than-average temperatures to heighten fire risks. The NWS in Cheyenne has advised caution with any outdoor burning or activities that could spark fires over the weekend.
The warm, dry weather pattern is expected to continue through much of next week, as high pressure remains dominant over the region. A brief cooldown is anticipated early next week when a cold front is expected to push through the area on Monday morning. This front will bring a temporary dip in temperatures to more seasonal levels.
Overnight lows on Monday and into Tuesday could drop enough to produce the first frost of the season in higher elevations, such as Laramie. In Cheyenne, temperatures are forecast to dip into the mid-30s, which might bring a light frost to some areas, though conditions remain uncertain.
By Wednesday, temperatures will start to rebound, with highs rising again as a downslope flow pattern sets up over southeast Wyoming and western Nebraska. The forecast remains dry through the middle of next week, with only a small chance of precipitation toward the end of the week as a low-pressure system in the southwestern U.S. potentially shifts northward.
