A Rowdy, Windy, Snowy Tuesday Night For Southwest Montana Mountains
The falling snow isn't supposed to last that long and the concern is mainly for higher elevations. But Tuesday night could get very messy with up to 5" of fresh snow and 45 MPH winds showing up for about 12 hours.
This appears to be a classic spring storm for the mountains of southwest Montana. The concern is that just enough rain or snow will fall along with cold enough temperatures - all of a sudden the valleys, too, are a slick mess.
Even if the valleys don't accumulate much snow, the temperatures will dictate how bad road conditions become. If it's not snowing, it will be raining at lower elevations and when temps drop after dark, the slick roads magically appear. According to the National Weather Service:
- WINTER WEATHER ADVISORY IN EFFECT FROM 6 PM TUESDAY TO 6 AM MDT WEDNESDAY.
- WHAT...Snow expected. Total snow accumulations between 2 and 5 inches.
- Winds gusting as high as 45 mph.

- Plan on slippery road conditions. Gusty winds could bring down tree branches.
- ADDITIONAL DETAILS...Snowfall through the day Tuesday will struggle to accumulate and pose impacts to roadways.
