Heat Risk Explained

A weak cold front this afternoon may be strong enough to generate scattered thunderstorms in the dark green area, mainly from 4 to 10 pm today. These storms have the capacity to generate wind gusts over 70 mph, so prepare now so that you are not caught off guard when and if these storms do develop. They will be moving northeast and into Canada later tonight.

An Excessive Heat Warning remains in effect until 6 am Monday. Highs today will be above 100 across northeast Montana with a few locations above 110 degrees. A cold front tonight will bring not as hot weather on Monday with highs in the 90s.

A Red Flag Warning is in effect from noon until 9 pm today for the Fort Peck Lake area along with Petroleum and Garfield Counties. The combination of extremely hot temperatures, single digit relative humidities, and south winds 10 to 20 mph with gusts to 30 mph will create critical fire weather conditions.

This weekend northeast Montana will experience the hottest temperatures of the year so far. Know the risks and what they mean, and how you can prepare for the heat. Stay hydrated and consider cancelling outdoor activities during the hottest parts of the day.
