GREAT FALLS — The National Weather Service has issued a Winter Weather Advisory for areas in and around Great Falls.

The advisory is in effect from 3 p.m. on Tuesday until 11 a.m. on Wednesday, and includes the following areas: Great Falls, Cascade, Belt, Kings Hill Pass, Fort Benton, Carter, Big Sandy, Brady, Conrad, Fairfield, Dutton, Raynesford, Stanford, Hobson, Lewistown, Winifred, Lewistown Divide, and Grass Range

NWS says that mixed precipitation is expected, with total snow accumulations of 1 to 3 inches at lower elevations, and higher accumulations to 5 inches at higher elevations, and ice accumulations of a light glaze.

Plan on slippery road conditions. Patchy blowing snow could significantly reduce visibility.

NWS says that rain will transition to snow from north to south late Tuesday afternoon through the evening. The highest likelihood for accumulating snow in the greater Great Falls area is after midnight Tuesday night and gradually diminishing through much of Wednesday morning. Breezy northerly winds Tuesday evening through Tuesday night could lead to patchy blowing snow and reduced visibility.

In addition, the NWS has issued a Winter Storm Warning for areas along and east of the northern Rocky Mountain Front; affected areas include Logan Pass, Marias Pass, Browning, and Heart Butte.

The NWS says that heavy snow is expected, with accumulations of 6 to 10 inches in the mountains and over Marias Pass, with 3 to 6 inches expected at lower elevations.

The Winter Storm Warning is in effect from 8 a.m. on Tuesday until midnight.

Temperatures will be much colder following this system, likely staying below freezing for most areas on Wednesday.

High pressure will once again rebuild on Thursday, allowing for more mild weather through the weekend.
