Minimal chance of afternoon thunderstorms, mid-70s high in Friday forecast for Cheyenne


CHEYENNE, Wyo. — Though the weather in southeastern Wyoming can change rapidly, the chance of thunderstorms impacting the region Friday should remain marginal.

The National Weather Service in Cheyenne is forecasting sunny skies with a high temperature of 76 degrees for Friday to close out the workweek, creating what seems to be an overall pleasant mid-August day for much of the morning and early afternoon in Wyoming’s capital city.

However, after 4 p.m. is when conditions could change, per the station. A 20% chance of rain and thunderstorms is in the forecast for late Friday afternoon and into the evening, potentially dumping some precipitation on Cheyenne in the process. The threat of severe weather should remain minimal to nonexistent throughout the day in southeastern Wyoming, per the National Weather Service’s Storm Prediction Center.

Winds are expected to blow to the northeast at 10–15 mph throughout the day. Friday night’s low is expected to dip down to 50 and be paired with partly cloudy skies and a 5–10 mph wind.


The radar that the Cheyenne station uses, currently located at the Cheyenne Regional Airport, is expected to be offline for upgrades for the next week, the station said Thursday afternoon. The station encouraged those who follow that radar to view surrounding ones for the time being.

All major roadways in and out of Cheyenne are open to traffic as normal as of Friday morning, per the Wyoming Department of Transportation.
