Here is the latest update from the National Weather Service office in Cheyenne on possible severe weather in southeast Wyoming and the Nebraska panhandle on Thursday, May 10:

Hazards: Multiple hazards possible. This includes very large and destructive hail
larger than golf ball size, damaging straight line winds in excess of 65 MPH, and
perhaps a couple of tornadoes. Frequent cloud to ground lightning will
accompany any given storm.

Areas Impacted: Southeast Wyoming and the western Nebraska Panhandle,
mainly along and east of I-25. The highest risk for a tornado is expected in the
western Nebraska Panhandle.

Timing & Duration: Thunderstorms will initially develop over the Laramie Range
during the early afternoon, likely increasing in coverage and intensity across the
high plains as they progress eastward. The threat for severe weather should
slowly diminish from west to east during the evening.

Impacts: Severe storms may pose a substantial risk to life and property. Outdoor
events may be impacted.

Certainty & Considerations: High confidence exists in the development of at
least a few severe thunderstorms. Some uncertainty exists with the overall
coverage of this activity. This being the first substantial risk for severe weather of
the season, people in this region should review severe weather safety rules and
make sure they have a way to receive watches and warnings.

UPDATE 4 a.m. Thursday, May 10: The map included with this article has now been updated to include Cheyenne in the area at highest risk for severe storms. The original map had Cheyenne just outside of the area predicted to be at highest risk of severe storms.
