BOZEMAN – A weak upper-level trough and Pacific disturbance is pushing into western Montana Monday afternoon producing scattered mountain snow and minor wintry travel conditions.

This weak disturbance will produce scattered mostly mountain snow showers over SW Montana Monday night into Tuesday. Valleys could see some off-and-on flurries as well but this system will be gone by Tuesday night or Wednesday morning.

Plan on some slow go travel conditions for most mountain passes with light snow, icy roads, and locally windy conditions Monday night through Wednesday morning.

A new High-pressure ridge will build over Montana beginning Wednesday and as the ridge gains strength look for a quiet weather pattern through next weekend. Travel conditions should improve greatly with this pattern with a few minor exceptions.

Valley inversions are likely to develop trapping low-level pollutants down close to the valley floor, some areas could see patchy dense fog at times, and temperatures could be colder in the stronger in the hardest hit inversion areas like Butte.
