BILLINGS — Arctic air will move out on Sunday
The remnants of an arctic air mass continues to bring pockets of cold air to much of eastern Montana Saturday afternoon and evening.
In the Billings area Saturday, temperature variances of 10 to 20 degrees were seen between the airport atop the Rims and portions of the valley.
Counties in northwest Montana have a Winter Weather Advisory in place through Sunday morning - another 1 to 3 inches of snow are possible along with light freezing rain.
Counties in northern and northeast Montana have a Wind Chill Advisory in place until 11 am Sunday - wind chills of 35 below zero will be common.
The cold air will scour to the east by Sunday allowing for much warmer temperatures to move in for Sunday and the work week to follow.
Expect daytime highs will jump 15 degrees into the upper 30s Sunday, and into the mid 40s by Tuesday.
Because of last week’s arctic freeze followed by rapidly warming temperatures, area waterways in south central and southeast Montana and portions of northern Wyoming could see some ice jamming through the weekend.
