WEATHER DISCUSSION: Areas of snow continue to create slippery travel overnight into the Monday morning commute across north central Montana. Overall, a general coating to 4 inches of snow can be expected. A cold front has already pushed through the region and continues to move further south. High temperatures will be 15-25 degrees colder on Monday than Sunday. Wind chills hover on either side of 0 degrees throughout the day.

The major winter storm impacting the Dakotas and upper Midwest is going to have little impact on central Montana. However, heavy bands of snow will impact eastern Montana, including Glasgow, on Tuesday lasting through Thursday morning. There will also be blowing and drifting snow, particularly east of Billings on I-94 and I-90. Expect major travel impacts in these areas. A weaker, clipper system brings another round of light snow showers to central and western Montana on Wednesday. Moisture will be fairly limited with Wednesday's system, keeping snowfall amounts on the lighter side.

Arctic air is forecast to settle into the region next weekend and sticks around through at least the Christmas holiday. An extended period of frigid, and potentially record-breaking, temperatures can be expected across Montana for the next couple of weeks. Highs may struggle to reach 0 degrees east of the Divide during the day and falling well below zero at night next week.
