Billings, Montana – Large, damaging thunderstorms are threatening communities from Billings to Casper this afternoon, with storms capable of unleashing up to 2.5-inch hail and wind gusts nearing 80 mph through 9 p.m. Tuesday. Residents across southern Montana and northern Wyoming should expect rapidly changing weather and hazardous driving conditions this evening.
According to the NOAA Storm Prediction Center, a severe thunderstorm watch remains in effect for cities including Billings, Bozeman, Cody, Sheridan, Riverton, and Casper until 9 p.m. MDT. Meteorologists warn that scattered thunderstorms could become severe, producing extremely large hail and isolated wind damage along highways like I-90, US-87, and US-20.
Power outages, downed trees, and significant property damage are possible, especially in exposed rural and urban areas. Emergency officials urge residents to move vehicles indoors, secure outdoor items, and avoid non-essential travel, particularly as hail can shatter windshields and winds may topple powerlines. This system echoes similar severe weather events from past Julys, with the potential to disrupt evening plans and commutes across the region.
The threat is expected to ease late tonight, but new advisories or warnings could follow if storms persist. Residents should monitor local alerts and be ready for updates as conditions evolve.
