A cold front is expected to move through the region on Thursday, bringing a drop in temperatures and lowering snow levels. If temperatures fall quickly below freezing, icy conditions could develop, especially after dark. Stay alert and use caution! Areas with the highest risk include I-90 near Butte and Homestake Pass, as well as Highway 12 near MacDonald Pass.
A cold front moving through on Thursday is expected to bring gusty west winds across north-central Idaho and western Montana. Travelers should prepare for possible slow travel over mountain passes due to reduced visibility and light snowfall, ranging from a trace to 4 inches.
Periods of pass level snow showers and a mix of rain and snow is expected for the valleys throughout the week. By late Thursday into Friday, snow levels may drop to valley floors with more widespread snow chances than earlier in the week. Watch for occasional slushy or snow packed roads on the passes, if you will be traveling.
