CHEYENNE, Wyo. — Showers and thunderstorms are expected today across southeast Wyoming, with Cheyenne having a higher chance this afternoon. The National Weather Service in Cheyenne warns of possible severe storms in a narrow corridor from Interstate 25 to US-26, mainly between early to mid-afternoon. Hail, gusty winds and heavy downpours are the primary hazards.
A very moist air mass is present in the region, with dew points reaching the mid-60s in some areas. Fog and low clouds are common this morning, particularly along the Platte River Valley. These conditions could persist into the afternoon, potentially affecting storm development.
Thunderstorms are expected to form quickly in Albany and Laramie counties by mid-afternoon. Laramie County, including Cheyenne, may see stronger storms due to a more unstable air mass. Some storms could become severe, with a risk of hail and damaging winds.
Seasonable temperatures will continue through the week. Wednesday through Friday will bring more thunderstorms, particularly in the late afternoon and evening, with the highest chance near the Colorado state line. The weekend will see fewer storms as drier air moves in, but conditions will remain warm, with highs in the upper 70s to near 90 degrees.
