Storm System Threatens Metro Detroit with Damaging Winds and Snow

Metro Detroit is bracing for a significant storm system that will impact the region from late Sunday through Monday. The 4Warn Weather Team has issued an alert for heavy winds, rain, and potential snow.

Storm System Overview

This storm will bring widespread rain, strong gusts, and rapidly decreasing temperatures to Southeast Michigan. Rain is expected to start late Saturday night, transitioning to all rain by Sunday afternoon. Some northern areas may experience brief periods of freezing rain on Sunday morning.

Rainfall and Flooding Risks

• Rainfall totals of 1 to 1.5 inches are anticipated.
• Localized areas could see nearly 2 inches.
• Minor flooding may occur in low-lying regions, but widespread river overflow is not expected.

Sunday evening is likely to be the warmest part of the storm, with temperatures expected to reach the 50s. However, a dramatic weather shift is anticipated overnight.

High Winds and Flash-Freezing

As the storm progresses into Monday, a powerful arctic cold front will sweep through the area, leading to the issuance of a High Wind Watch. Winds from the west to southwest may range between 25 to 35 mph, with gusts potentially hitting 50 to 60 mph.

• Risks include downed tree limbs and power lines.
• Travel conditions will be hazardous, particularly for larger vehicles.

Rapid temperature drops on Monday morning could exceed 20 degrees in a few hours, raising the risk of flash freezing on wet roads from Sunday’s rain. Snow showers and isolated squalls are also forecast for Monday, resulting in visibility challenges and hazardous travel conditions.

Travel Impacts and Marine Conditions

• Drivers should expect icy roads and strong crosswinds.
• Air travel may face delays due to adverse weather conditions.
• Marine conditions on the Great Lakes will be perilous, with gale-force winds and high waves.

Cold Weather Ahead

The cold snap will persist into the New Year’s holiday week. Highs are expected to hover in the upper 20s to near 30 degrees on New Year’s Eve, with a chance of light snow.

Residents are advised to stay updated with 4Warn Weather forecasts as conditions may change rapidly. It’s essential to be prepared, especially for Monday’s adverse weather.
