MISSOULA - Thanksgiving travelers should be prepared for winter driving the next 24 hours, with some snow already impacting over the Continental Divide.
Cooler air pushing into Idaho and Western Montana today is already creating a drop in snow levels, with the National Weather Service issuing several different watches and warnings.
A Winter Weather Advisory is up for most of Western Montana with several inches of snow expected at the higher elevations, with the possibility of mixed rain and snow in the lower valleys overnight.
High wind warnings are posted for Madison County, and especially Highway 287 over Norris Hill.
But winter driving conditions are already showing up this morning along the Divide passes, with areas of blowing snow and snow covered roads on Marias, Rogers and MacDonald passes. Drivers on Interstate 15 are hitting snow from Feeley Hill north through Butte to Boulder, although Monida Pass has just scattered wet roads.
Interstate 90 has wet roads on Lookout Pass, although it was snowing this morning from Drummond east over Homestake Pass. Both Lolo and Lost Trail passes were seeing fresh snow, with snowcovered roads. All three of the passes over the Bitterroot Divide may see heavy snow showers and blowing winds overnight.
Travel conditions should improve on Thanksgiving Day with more snow possible as people are coming home on Sunday.
