A WINTER WEATHER ADVISORY has been issued for southwest and northeast Montana into Wednesday. A WIND CHILL ADVISORY remains in effect for most of the state into Wednesday afternoon. The current pattern affecting Montana will likely be the harshest conditions of this winter when all’s said and done. The problem is this pattern will last for quite a while, meaning subzero temperatures and periods of snow will continue at least the next two weeks. Another round of snow will come through overnight into Wednesday morning. The snow will be light, but it will be widespread. Generally a coating up to a couple inches will accumulate. Wednesday will be cold again with highs between -10 to 10, and wind chills will be between -15 to -35. Snow will taper off through the morning, and the clouds will begin to break up Wednesday evening. Clear skies Wednesday night will allow for some of the coldest temperatures this winter. Lows will dip to near -20 for many, but some of the normally colder spots could become colder than -30. That’s without the wind. Some cars may have a tough time starting early on Thursday. Thursday will be a mostly sunny day and temperatures will warm into the 0s and 10s by the afternoon. One potential issue will be blowing snow off of the Rocky Mountain Front as wind increases. Also as the wind increases, wind chills could be colder even though the air temperatures will be slightly warmer. Friday and Saturday will have another round of snow with a reinforcing shot of arctic air. Temperatures will likely fall back below zero Friday night and Saturday. This weekend will be very cold, white and gray. There will be light snow on Saturday, with mostly cloudy and gray conditions for Sunday. More snow and cold are likely Monday and Tuesday. This harsh winter weather will continue through most of next week as well.
