Snow levels tonight will drop as low as 4000-4500 feet, which means that the mountains, mountain passes, and some lower elevation locations will see some snow accumulation. A few isolated thunderstorms are also possible this evening and early tonight, especially in north-central Montana. We are also going to have mostly to partly cloudy skies tonight, with the cloud cover decreasing from north to south, especially during the second half of the night.

It is also going to be breezy tomorrow in portions of central and north-central Montana as sustained wind speeds are going to be between 10 and 25 mph, with the strongest wind along the Rocky Mountain Front. We are also going to have pleasant temperatures again tomorrow as highs are going to be in the mid to upper 50s and low to mid 60s.
On Wednesday, we are going to have partly cloudy skies, dry conditions, and pleasant temperatures as highs are going to be in the low to mid 60s in most locations.
