A WIND CHILL ADVISORY is in effect for parts of the Hi-Line and along the Canadian border into Thursday morning.
An AVALANCHE WARNING is in effect for the mountains of Madison and Gallatin Counties.

Just a little light snow moved through Montana on Wednesday. The snow was fluffy and pretty, adding to what's on the ground and in the trees. While the snow looks pretty now, that's about to change over the next several days as wind and warmer temperatures turn what's on the ground into a sloppy mess.
Wednesday night and Thursday morning will be cold, as Canadian air has moved back into the state. Lows will drop into the -0s and 0s, with wind chills as low as -30 near the Canadian border. Thursday will start out cold and sunny, with some clouds increasing over the western part of Montana late in the day. Highs will generally be in the 10s and 20s. Southwest wind off of the Rocky Mountain Front will increase to near 25mph creating some areas of blowing snow. Friday will have scattered snow showers near the mountains, but the wind will increase for most of the state. Blowing snow could impact travel over the plains and the mountain passes. Highs will warm into the 30s and 40s, so melting snow will make for sloppy conditions. Some snow showers will continue in the mountains through Friday night and into Saturday. Saturday will be partly cloudy with those scattered snow showers. Highs will warm into the 30s and 40s, with west wind up to 30mph. Sunday will have increasing clouds and wind. The wind will be strong with gusts possibly exceeding 50mph across the plains. Blowing snow will be an issue for the Rocky Mountain Front. Highs will again be in the 30s and 40s. Monday will be mild and windy with a few areas of rain and snow moving through in the afternoon. The precipitation will not be heavy. Snow showers and cooler temperatures are likely for the middle of the week.
Have a great day.
