BOZEMAN – The last snow storm to impact Bozeman was back on December 1st so this roughly 10 day stretch of dry weather is coming to an end starting Monday evening.

Several pacific storms will pass through the Pacific NW and Northern Rockies for the first half of the new work week. The first storm looks to be weaker with a quick shot of snow Monday evening into early Tuesday morning. Mountain passes could see 1″ – 3″ of snow and minor travel impacts.

Second storm system will have a higher probability of measurable snow at all levels. Early estimates (likely to change) are for 1″ – 4″ for most not all valleys and 2″-4″ for most mountain passes. Greatest impacts will be along the MT/ID state line mountain passes.

This second system will have a stronger cold front so look for increasing surface winds in wind prone areas Tuesday into Wednesday. Livingston for example could see wind gusts over 50 mph at times.
