There was then widespread rain around for a good chunk of today in north-central Montana, with parts of the Hi-Line receiving the most rain.

Cut Bank received .53” of rain during the day today, making this the wettest day since August 21, 2023, which was 661 days ago! The graphics below show some the 36 hour rain totals as of 5pm on June 12, 2025.
There will continue to be some haze around over the next couple of days. Visibility may be reduced some, but the air quality won’t be impacted much, as most locations will have “good” or “moderate” air quality.
There will be some scattered showers and thunderstorms around this evening. There are then just going to be isolated showers and thunderstorms around tonight. We are also going to have mostly to partly cloudy skies tonight with areas of fog around, especially in the Golden Triangle and along the Hi-Line, and some of this fog may be dense with visibility as low as a quarter mile. It is also going to feel nice outside tonight as lows are going to be in the mid to upper 40s and low to mid 50s, and it will continue to be breezy tonight in northeastern Montana as sustained wind speeds are going to be between 10 and 20 mph
For tomorrow, we are going to have partly cloudy skies with areas of fog around during the morning in north-central Montana, and some of this fog may be dense. Another round of scattered showers and thunderstorms is also expected tomorrow. The main batch of showers/storms is currently forecasted to impact western portions of north-central Montana (including the Rocky Mountain Front and Cut Bank/Great Falls) and the Helena area from the late morning through the early evening (~11am-4pm); central portions of north-central Montana (including Havre and Lewistown) during the afternoon and evening (~1pm-7pm); and northeastern Montana (including Malta and Glasgow) during the evening (~4-10pm). These times are approximate and may vary by an hour or two.
Some of the thunderstorms that develop tomorrow will be severe with damaging winds (58+ mph) and/or large hail (1+” in diameter). There is also a very slim chance that a tornado could develop later on tomorrow. Severe or not, all thunderstorms tomorrow will be capable of producing gusty winds, heavy rainfall, small to medium-sized hail, and frequent lightning, so please keep an eye to the sky if you are going to be outdoors at all!
It is also going to be mild tomorrow as highs are going to be in the 70s. Breezy conditions are also expected tomorrow along the Divide and the Rocky Mountain Front as well as in northeastern Montana as sustained wind speeds are going to be between 10 and 20 mph.

A couple severe thunderstorms will also be possible Saturday afternoon/evening east of I-15. There are also going to be some areas of fog around Saturday morning in north-central Montana. We are then going to have increasing clouds on Sunday with some scattered showers and thunderstorms around, generally during the afternoon/evening, as another disturbance impacts our area.
It is also going to be mild/warm this weekend as highs are going to be in the mid to upper 70s and low to mid 80s.
