Special Weather Statement issued December 5 at 5:32AM MST by NWS Great Falls MT
Additional Details Here.
A band of snow is expected to move from east to west across the area early this evening. This band of snow should arrive along the Rocky Mountain Front between 4 and 5 PM, then move eastward across the Dillon, Boulder, Helena, Great Falls, Bozeman and Cut Bank areas between 5 PM and 11 PM this evening. Expect a quick burst of snow and gusty winds as this band of snow moves through. There is the potential that if the snow is heavy enough and arrives early this evening, that snow squall warnings could be issued. Do expect winds gusting over 40 mph for a short time when the snow moves through, which will also reduce visibility. Those that have outdoor plans this evening or plan to travel, should check later forecasts for updated timing of when this band of snowfall will move through.
