Showers and thunderstorms are likely in central and western Montana this evening and tonight as a cold front passes through our area. Some of these thunderstorms may also be severe with damaging winds (wind gusts up to 70 mph) being the main hazard, but isolated large hail (up to 1” in diameter) is also possible. We are also going to have partly cloudy skies tonight, and it will continue to be hazy tonight in northeastern Montana.
Also, as the cold front passes through, a period of gusty winds (gusts up to 40 mph) is expected. Outside of that, it will be breezy tonight in eastern portions of north-central Montana, and the wind will increase later on tonight in locations along and just east of the Continental Divide.

It is also going to be a lot cooler tomorrow than it was today in central Montana as highs are going to be in the 60s and 70s. In eastern Montana, it will be cooler tomorrow than it was today, but it is still going to be warm as highs are going to be in the 80s.
There are also going to be scattered showers and a few thunderstorms around tomorrow, especially during the afternoon/evening, and tomorrow night as a storm system slowly works its way through our area. We are also going to have partly cloudy skies tomorrow, with increasing clouds during the afternoon and evening. We are then going to have mostly to partly cloudy skies tomorrow night.
On Thursday, we are going to have partly cloudy skies with a few scattered showers and isolated thunderstorms around, generally during the morning and generally in locations east of I-15 in north-central Montana, as tonight/tomorrow’s storm system finally departs our area. We are also going to have gusty winds around on Thursday as sustained wind speeds are going to be between 10 and 30 mph, and wind gusts over 40 mph are possible.
