Detroit, MI – A developing low-pressure system passing through Ohio is expected to bring a mix of light snow, rain, and slick travel conditions to metro Detroit throughout Tuesday, according to updated guidance from the National Weather Service in Detroit/Pontiac. The system will influence the region from the early morning hours through the evening, creating a day of changing weather and shifting road conditions across southeast Michigan.
A push of colder air overnight allowed light snow to begin early this morning, coating grassy surfaces and rooftops across several counties. Forecasters note that the snow is expected to continue through the late morning before warmer air moves in from the south. Once that warmer layer arrives, snow will gradually mix with rain, and some areas may experience brief sleet during the transition phase.
Expected Snowfall Totals Across Southeast Michigan
Forecasters anticipate light accumulations, generally between a dusting to 0.5 inches, with slightly higher totals possible along and north of I-94 and perhaps up toward I-69, where temperatures may stay colder for a longer period.
These amounts are expected to fall mainly on grassy or elevated surfaces, as pavement temperatures remain warm enough to limit road accumulations.
A few quick highlights from the forecast include:
- Light snow early, becoming mixed precipitation by midday
- Highest risk of slick spots on bridges and overpasses
- Road temperatures likely to stay warm enough to reduce widespread travel impacts
How Temperatures Will Shape Tuesday’s Weather
Early morning temperatures fall into the 20s, keeping snow intact for the first part of the day. By afternoon, temperatures rise into the mid to upper 30s, encouraging a changeover to light rain or drizzle.
This transition means the most slippery travel is possible before noon, especially in shaded or untreated areas.
Road crews are not expecting major issues, but meteorologists warn that pockets of ice could still develop where heavier bursts of snow occur or where temperatures lag behind the main warm surge.
Travel Impacts for the Detroit Metro Area
While this is not a high-impact winter storm, timing plays a critical role.
The morning commute coincides with the coldest part of the day and the period of steadier snow, making this the most likely window for travel difficulties.
Forecasters highlight these key concerns:
- Slick bridges and overpasses as the day begins
- Reduced visibility at times during heavier flurries
- A messy mix for drivers on I-94, I-96, and M-59 through midday
Motorists are advised to allow extra time, reduce speed where conditions appear wet or slushy, and stay aware of rapid changes in precipitation type.
How Long the Wintry Mix Will Last
The system is expected to gradually weaken by late afternoon and evening.
By tonight, lingering drizzle and flurries will taper off completely, allowing temperatures to stabilize.
Wednesday brings a notably different pattern:
- Partly sunny skies
- Dry conditions
- Highs returning to the mid-40s
This short-lived system is typical of transitional November weather, where early-season cold air interacts with warmer southerly flows, creating mixed-precipitation events that can be challenging for commuters.
Official Commentary and Forecast Notes
Meteorologists at the National Weather Service Detroit/Pontiac emphasize that while this system is not expected to produce significant accumulations, slight shifts in temperature—even by just a degree or two—could change how long snow lasts or how quickly rain develops.
“Minor temperature changes can make all the difference in how slick roads become early Tuesday,” forecasters noted in their morning discussion, which can be found through the National Weather Service Detroit/Pontiac update integrated into today’s forecast cycle.
Residents across southeast Michigan are encouraged to stay updated with any new advisories or short-term forecasts should conditions trend slightly colder than expected.
Final Takeaway
A light but messy wintry mix is expected across the Detroit area today. While not a major winter storm, the combination of early-morning snow, a midday changeover to rain, and spotty slick areas could still complicate travel. Warmer temperatures later in the day and drier weather by Wednesday will help melt any remaining accumulation.
