The National Weather Service has a WINTER STORM WARNING up now through Friday afternoon for most of Western Montana and along the Continental Divide including I-15 from Butte to Great Falls. 

Moderate to heavy wet snow is likely and will have a significant impact on travel in the warning areas. Travel is not recommended. If you do hit the roads you will experience moderate snowfall, low visibility and wet roads quickly turning to icy. Another severe weather element will be strong gap winds along the divide. NE winds 15 to 30 mph with occasional stronger gusts will produce considerable blowing snow.


The National Weather Service has a WINTER WEATHER ADVISORY up now through Friday afternoon for the Bozeman – Ennis areas.

Rain or snow mix through early Thursday evening is possible but likely to change to all snow after sunset into the early morning hours Friday. Valleys snow should be on the lighter side but at pass level 3" – 6" is possible.

The biggest concern for travel is wet roads quickly turning icy overnight and remaining icy for your Friday morning commute.

Watch for some minor flooding issues especially around smaller streams and creeks. Rainfall forecasts has the potential for 0.50" to 1.00"+ Saturday afternoon through Sunday morning. Most valleys have snow on the ground and with warming temperatures and moderate rainfall rapid snow melt is likely and could produce flooding issues.
