Frigid air hangs around

Don't put away your heavy winter gear just yet, because that frigid air isn't going anywhere anytime soon.

Warmer air will penetrate parts of western and southern Montana in the days ahead, pushing temperatures back into the 20s. However, the warm-up will be short-lived with colder air returning again late week.

Major snow event predicted

The STORMTracker Weather Team says a major snow event will create significant travel trouble this week.

With abundant moisture streaming in from the west, widespread heavy snow is likely across the Treasure State.

Meteorologist Mike Rawlins says light snow will develop as early as Wednesday morning as an upper level disturbance rolls over the region.

Periods of light-moderate snow are likely through Wednesday night, with a few inches of snow falling at lower elevations.

The mountains will get hit with 5-12" of snow during this period, making driving difficult through the passes.

This first round of snow will make roads snowy and icy again for travelers, but the main event is expected to begin late Thursday.

Rawlins says a stronger disturbance is on track to move in Thursday night and Friday, producing widespread heavy snow.

Snow totals could top one foot in spots, making getting around very difficult.

Significant travel impacts are expected, and anyone hitting the road should be prepared for extreme driving conditions.
