There is a chance for dense fog to develop tonight along the Hi-Line into Northeastern Montana. If heading out, be prepared for sudden changes in visibility and make sure to keep plenty of distance between vehicles.

There are signs that colder air will spill into the northwest portion of the country as we get into the week of Thanksgiving. This forecast from the Climate Prediction Center shows that temperatures could be near normal or slightly below with precipitation chances slightly above normal, so snow is possible. Stay tuned to the forecast as Thanksgiving draws closer. If you have travel plans, now would be a good time to include a Winter Survival kit in your vehicle.
