Severe Weather Threat for Northwest Wyoming Today

The National Weather Service
Building a Weather-Ready Nation


Summary | Monitoring & Reporting | Safety

A strong low pressure system will move toward western Wyoming this afternoon.  Strong thunderstorms may form ahead of an approaching cold front over the area.  These storms will be fast moving mainly from south to north and could produce very strong to severe wind as they move across Star Valley, Jackson Hole, and Yellowstone National Park.  Hail shold be present in stronger storms but wind will be the primary threat.  Once the front moves through this afternoon and evening, snow is possible in the high country and over all of Yellowstone National Park so be prepared and remember a jacket if you need to be outside this evening.

Please call us at 1-800-211-1448 with any reports of hail or strong wind and any associated damage.  You can also report via facebook and post any pictures of weather damage.  Just go to www.facebook.com/US.NationalWeatherService.Riverton.gov.

Thunderstorms can and do form suddenly and could turn a sunny day into a stormy one in a matter of minutes. Thunderstorms that do form today are capable of producing hail, damaging winds, and frequent lightning. You do not want to find yourself without shelter in these storms!
