CHEYENNE, Wyo. — Severe thunderstorms capable of producing large hail, damaging winds and tornadoes could hit southeast Wyoming this afternoon and Tuesday.
The National Weather Service issued a level two out of five slight risk for the eastern high plains on Monday.
Cheyenne has a 30% chance of showers and thunderstorms after 3 p.m. today, with a forecast high near 73 degrees. Winds will shift from the northwest to the southeast at 10–15 mph during the morning hours. Storm chances drop to 20% before 9 p.m., and areas of fog will develop after midnight as temperatures fall to a low around 52.
Tuesday brings a repeat of storm threats after noon. Morning fog will give way to mostly cloudy skies, which will gradually clear later in the day with a high near 75. Low-level moisture and atmospheric spin along and east of the Interstate 25 corridor could trigger severe conditions, with large hail listed as the main threat.
Showers remain possible mid-week, with a 50% chance of rain on Wednesday afternoon and a high near 77 degrees.
A drying and warming trend will settle over Laramie County starting Thursday. High temperatures will climb to 79 on Thursday, 82 on Friday, and peak at 85 under sunny skies on Saturday.
Any remaining storms later in the week will likely produce high winds rather than rain due to dry air near the surface.
