Weather instability in Wyoming and surrounding regions

Overview

Unsettled weather patterns impacted southeast Wyoming and surrounding areas in mid-to-late September 2026.

Initial forecasts for southeast Wyoming predicted heavy rain and thunderstorms driven by a tropical system from the Gulf of California. This system brought risks of excessive rainfall and winds exceeding 60 MPH east of Interstate 25. In the Jackson area, a slow-moving low-pressure system brought unusual moisture, resulting in intermittent showers and a cooling trend.

By the following week, weather conditions transitioned to variable autumn patterns. Cheyenne County and parts of Colorado experienced patchy fog with low visibility and flood advisories following previous severe storms. The period concluded with a mix of sunshine and isolated midweek rain, accompanied by wind gusts of 30 mph or higher and cool temperatures.
