Severe Storm System to Impact Metro Detroit with High Winds and Snow

A significant storm system is set to impact Metro Detroit from late Sunday through Monday, bringing heavy rain, strong winds, and snow. The National Weather Service has issued a High Wind Watch for southeast Michigan, effective from late Sunday night through Monday evening, with west winds of 25 to 35 mph and gusts up to 60 mph possible.

Rain is expected to develop late Saturday night into Sunday morning, with northern areas, particularly north of M-59, potentially experiencing brief freezing rain early Sunday, leading to isolated slick spots on untreated roads and bridges. Temperatures are anticipated to rise quickly after sunrise, changing precipitation to all rain. Rain will become widespread Sunday afternoon and evening, with many locations receiving 1 to 1.5 inches, and localized totals near 2 inches possible. Minor flooding in poor drainage or low-lying areas may occur, though widespread river flooding is not expected.

The most significant impacts are expected late Sunday night into Monday as a powerful arctic cold front sweeps through Southeast Michigan. West to southwest winds of 25 to 35 mph, with gusts reaching 50 to 60 mph, could down tree limbs and power lines, resulting in scattered power outages and hazardous travel conditions, especially for high-profile vehicles. Residents are advised to have fresh batteries and a flashlight available.

Temperatures will drop rapidly Monday morning, falling more than 20 degrees in just a few hours. With roads wet from Sunday's rain, this creates a high risk of flash freezing, particularly during the Monday morning commute. Snow showers and brief snow squalls are also possible throughout the day Monday. While snowfall totals will be low—ranging from a dusting to 1 to 2 inches—squalls may cause sudden reductions in visibility and rapidly deteriorating road conditions. Wind chills Monday will fall into the teens and single digits, adding to the danger for anyone outdoors.

Drivers should be prepared for strong crosswinds, icy roads, and rapidly changing visibility on Monday. Airline travelers may encounter delays due to strong winds and reduced visibility. On the Great Lakes, hazardous marine conditions are expected with gale-force winds and very high waves.

Cold conditions are expected to linger into the holiday week. Wednesday (New Year's Eve) is forecasted to be mostly cloudy and cold, with highs in the upper-20s to near 30 degrees, and a few light snow showers possible. Thursday (New Year's Day) is expected to remain cold, with highs in the lower- to mid-20s and a chance of light snow.

Residents with travel plans Sunday or Monday are encouraged to monitor weather forecasts closely and prepare for rapidly changing weather conditions.
