Southeast Wyoming Starts Calm Before Thunderstorms Move In
Southeast Wyoming is beginning the day with some calmer weather but the quiet weather may not last long.

The National Weather Service in Cheyenne says there is a slight risk for severe weather over the eastern high plains with large hail, damaging winds and an isolated tornado possible.
Why is South-east Wyoming so Quiet Early?
The morning hours are expected to be quieter as storms usually need daytime heating, moisture and lift before they can strengthen. Light winds, cool early temperatures and partly cloudy skies can create the illusion of a stable start to the day.” But that stable pattern can flip quickly as soon as the atmosphere becomes warmer and more unstable.

- Cloudiness may increase during the day.
- Humidity could aid storm growth later.
- Winds can be gusty around thunderstorms.
When do thunderstorms arrive?
The chance of thunderstorms is increasing, mainly in the afternoon and evening. The National Weather Service forecast around Cheyenne calls for a chance of showers and thunderstorms after 3 p.m. Tuesday, with more slight chances Tuesday night and again Wednesday afternoon. Residents should watch the sky after noon if they have outdoor work, school activities or travel plans.
What storm hazards could we see?
The heaviest storms might unleash more than a quick downpour.

What will travel be like?
Drivers along Interstate 80, Interstate 25 and local highways should be prepared for rapidly changing weather conditions. “Thunderstorms can produce brief periods of heavy rain, hail, low visibility and strong crosswinds. Storms also can generate strong outflow winds over open stretches of roadway that could make high-profile vehicles harder to control.
