CHEYENNE, WY – Residents across southeastern Wyoming and the Nebraska Panhandle should stay weather-aware this afternoon as scattered thunderstorms are expected to develop — some of which may turn severe. The National Weather Service in Cheyenne warns of gusty winds, large hail, and frequent lightning, particularly during the afternoon and evening hours.
Timing of Storms
Wyoming (southeast):
Highest risk between 2 p.m. and 7 p.m.
Nebraska (Panhandle & west):
Strongest storms likely from 4 p.m. to 9 p.m.
Storm activity is expected to begin as scattered showers but could quickly intensify into isolated severe thunderstorms across the region.
Main Threats
The most intense storms could bring:
Damaging wind gusts
Hail up to or exceeding severe limits
Frequent and dangerous lightning
Sudden downpours, reducing visibility for drivers
These conditions could develop rapidly, especially in areas with unstable late-summer air, making it crucial to have multiple ways to receive weather alerts.
Travel & Outdoor Impacts
Drivers on Interstates 25 and 80, and U.S. Highway 85, should expect:
Reduced visibility
Slippery roads
Delays due to storm-related hazards
If you’re planning to be outdoors, whether for events, errands, or commuting, officials strongly recommend:
Moving indoors at the first sign of thunder
Securing outdoor furniture or items
Avoiding open fields or high points during storms
Safety Tips from NWS
Stay indoors during thunderstorms
Charge devices in case of power outages
Avoid travel during peak storm hours if possible
Keep weather radios or apps active for real-time alerts
Looking Ahead
The storm system is part of a late-summer instability pattern moving across the northern Plains. After tonight, conditions are expected to calm down by early Thursday, bringing milder and more stable weather to both Wyoming and western Nebraska.
With severe storms possible this afternoon and evening, residents in Wyoming and western Nebraska are urged to take precautions now. Whether you’re on the road, at work, or outdoors, stay informed and prepared. The weather may calm by Thursday, but for today, stay alert and put safety first.
