The Cheyenne Office of the National Weather Service says strong to severe thundershowers are possible in southeast Wyoming on Friday and Saturday.

The agency posted this statement on its website on Friday morning:

"Afternoon and evening thunderstorms continue today, though more widespread than it’s been these last two days. Some storms may be strong to severe, mainly along and east of the I-25 corridor. Saturday will bring the passing of an unseasonably strong cold front through the High Plains and Mountains. Storms may again be strong to severe, conditions breezy, with temperatures rapidly falling in the front’s wake. By Sunday morning, temperatures will be between 35 and 45 degrees across the region, 20s in the mountains. Sunday will be much cooler with daytime temperatures 10 to 15 degrees below normal. A warming trend will bring warmer temperatures to the region beginning next week."
