BOZEMAN – A deep trough of Low-pressure is sitting over Montana and extends all the way down to southern Nevada. This has opened the door to much colder air to sink southward changing rain to snow and creating extremely icy and snow-covered roads.
Locally windy conditions is producing areas of blowing and drifting snow with blizzard like travel hazards across central and northern Montana counties.
The storm continues over Montana Sunday afternoon as a surface Low spins up into NE Montana tonight and begins to move out of the region by Monday morning. Watch for scattered snow and gusty winds in SW Montana to continue to produce winter-like travel conditions.
Monday’s morning commute will be a slow-go with snow-covered and icy roads and areas of light snow. Temperatures will drop around zero tonight and with a light wind, windchills could be below zero Monday morning.
Temperatures Monday through Friday will continue to be cooler than normal but slowly moderate back up to or slightly above freezing. This should help thaw most roadways but look for melting during the day and re-freezing again at night. Morning commutes take longer for the first half of next week.
A few weak disturbances will produce scattered snow showers as we go through next week, but snow accumulations should be on the lower side.
