Cheyenne, Wyoming – Drivers along I-25 could face changing road conditions within the next 48 hours as scattered showers ramp up into a more organized storm pattern heading into the weekend, with the greatest disruption expected by Saturday afternoon.
According to the National Weather Service in Cheyenne, isolated showers remain light through Wednesday and Thursday, but precipitation chances climb to 35–50% by Friday as a cooler air mass settles over southeast Wyoming. Highs will range from the mid-50s to near 70 degrees, with overnight lows dipping into the 20s and 30s.
