Powerful Storms Rumble Over the Northern High Plains

Severe thunderstorms will develop over portions of the northern High Plains this afternoon and evening.

A potent upper-level weather disturbance will help spawn scattered to numerous showers and thunderstorms across parts of Montana and Wyoming this afternoon. These storms will move over the western Dakotas and northwestern Nebraska this evening before dissipating overnight. 

Given plenty of warm, unstable air in place across the region, the government's Storm Prediction Center has placed Enhanced and Slight Risks across portions of Montana, Wyoming, southwestern North Dakota, western South Dakota, and northwestern Nebraska. 

A Severe Thunderstorm Watch is in effect for portions of central and eastern Montana and northeast Wyoming. Cities include Lewiston, Billings, Jordan, Glasgow, and Miles City, Mont., and Sheridan and Gillette, Wyo. 

Damaging wind gusts in excess of 60 mph and large hail will be the primary threat from thunderstorms today. However, an isolated tornado or two cannot be ruled out. Cities such as Billings, Mont., Sheridan, Wyo., and Rapid City, S.D. are all under this risk today. 

A few stronger thunderstorms may also develop across the central Plains to the Upper Midwest along and ahead of an advancing cold front. Cities such as Denver, Kansas City, Mo., Des Moines, Iowa, and Milwaukee could experience thunderstorms capable of producing wind gusts in excess of 50 mph, small hail, and heavy downpours. 

Make sure to know the difference between a watch and a warning should they become issued. A “watch” means that conditions are favorable for severe weather to occur and to be on alert for any rapidly changing conditions. A “warning” means that severe weather is imminent, and you should act fast to remain safe.

The best way to remain safe is to stay prepared and informed about your local weather. Have a severe weather kit packed with a battery-operated radio, water, and non-perishable food items should you be without power for long periods of time. Also, check the WeatherBug app frequently for any updates on today's severe weather. Remember, "When Thunder Roars, Go Indoors!"
