A High Wind Warning will be in effect for all of Southeast Michigan from 12 a.m. Monday until 9 p.m. Monday, as a powerful storm system brings damaging winds, hazardous travel and the potential for power outages to the region.
West winds are expected to increase rapidly overnight, with sustained speeds of 25 to 35 mph and gusts reaching 50 to 60 mph. The strong winds, combined with saturated ground from heavy rainfall, increase the risk for downed trees, power lines and scattered power outages. Travel could be difficult at times, especially for high-profile vehicles.
Before the winds ramp up, widespread rain will continue Sunday, with rainfall totals of 1 to 2 inches expected across parts of Southeast Michigan. The heaviest rain will fall through the afternoon and evening, raising the risk for ponding on roads and localized flooding, particularly in low-lying and urban areas.
Scattered thunderstorms are also possible Sunday evening, and a few storms could become strong, mainly south of I-94. The primary threat with any stronger storms will be gusty winds, which could briefly exceed 50 mph.
As a strong cold front sweeps through late Sunday night, temperatures will drop sharply. Temperatures will rise into the 50s during the evening, ahead of cold air forcing temperatures down 20 degrees or more in a matter of hours before dawn. Rain is expected to change to snow by daybreak Monday, and the rapid temperature fall could lead to a flash freeze on untreated roads, sidewalks and bridges, especially during the Monday morning commute.
On Monday, snow showers and snow squalls are possible, producing brief periods of reduced visibility and sudden whiteout conditions. While snowfall totals are generally expected to range from 1 to 2 inches, the combination of blowing snow and strong winds could make travel hazardous at times throughout the day.
Due to the combination of damaging winds, slick roads and snow squalls, a 4Warn Weather Alert is in effect for Monday.
Looking Ahead
Colder air will remain in place through the middle of the week. Seasonably cold temperatures are expected for New Year’s Eve on Wednesday night and New Year’s Day on Thursday, with highs generally in the 20s and lower-30s. Periodic chances for light snow may linger into midweek, though no significant accumulation is expected at this time.
Residents are urged to secure loose outdoor items, prepare for possible power outages and use caution if traveling, especially Sunday night through Monday evening. Be sure to have a flashlight and fresh batteries available.
