WEATHER DISCUSSION: The high winds become less of a concern throughout Sunday night. However, gusts up to 40 MPH are still possible throughout central Montana on Halloween. Other than the wind, dry and mild conditions are expected for trick-or-treaters. A calmer day is expected on Tuesday with less wind and continued mild temperatures ahead of a major pattern change.
A cold front moves across the region Tuesday night bringing with it gusty winds, cold temperatures and snow showers. A widespread, accumulating snow will impact the Wednesday morning commute, along with very chilly temperatures as temperatures remain in the upper 20s and lower 30s throughout the day. High pressure briefly gains control of the region on Thursday, however cold air remains in place.
Strong wind gusts are likely across the plains Friday and Saturday as another storm system pushes into the region. A shot of arctic air is likely for the second half of the weekend and into the following week. This has the potential to be the coldest air of the season thus far.
