Snow levels will initially be around 5000 feet on Friday, with snow levels around 4000 feet Saturday and Sunday. Please monitor the latest river forecasts from the National Weather Service for additional information.

ESFBIS Colder weather returns to the region on Tuesday with daily low temperatures in the single digits, and even colder weather to follow for the foreseeable future. This will once again cause ice to form on the Missouri River. While the river came close to icing-in just before Christmas, a return to warmer weather reversed that trend and removed some ice from the Bismarck and Mandan area. This time around, there is much less room in the river to store ice below the University of Mary, so the icing-in will likely occur very quickly once it starts. While it is
