Detroit, MI – Michigan residents may want to prepare for a colder and snowier stretch heading into the holidays, with the latest NOAA Week 3–4 Outlook signaling a strong chance for below-normal temperatures from December 20 through January 2. The period covers both Christmas and New Years, raising the possibility of a wintry travel setup across the state.
According to NOAA forecasters, a broad area of colder-than-normal air is expected to settle over Michigan, northern Illinois, Wisconsin, Minnesota, Iowa, and the Dakotas, creating favorable conditions for snow development during the holiday period. With temperatures trending below normal, even areas receiving near-normal precipitation could still see accumulating snow, especially across northern and western Michigan.
For precipitation, the outlook places much of Michigan in a zone of above-normal precipitation, particularly across the central and eastern parts of the state. This increases the potential for multiple snow events, slick roads, and travel delays between Dec. 20–Jan. 2. Holiday commuters should monitor daily forecasts closely, as timing and intensity will determine whether Michigan sees a White Christmas, a snowy New Years, or both.
In southern counties—where temperatures will still run below average—precipitation may begin as a mix before transitioning to snow. Lake-effect snow belts along Lake Michigan also have an elevated chance of receiving enhanced snowfall, depending on wind direction.
Residents are encouraged to prepare vehicles, allow additional travel time, and watch for rapidly changing conditions. More detailed system-by-system forecasts will be issued as the period approaches.
