The National Weather Service has issued a winter weather advisory for Ford and Iroquois counties from 12 p.m. Friday until 12 a.m. Saturday. Snow showers this evening and tonight look to be lighter, but still capable of depositing a few inches in localized spots near the shoreline. Highways will be snow-covered, slippery and traffic will be slowed considerably during the afternoon/evening commute. The heavier amounts will likely be focused on the USA 30 and Interstate 80 corridors, where snowfall rates of an inch or more per hour will lead to rapid accumulation and very poor visibility for the evening commute. Saturday will see another high in the mid-20s.
Above you can see a stream of subtropical moisture is following the jet stream right into the Pacific NW and rolling over into Montana. Skies will remain mostly cloudy the rest of the overnight hours.
