Ann Arbor weather

Ann Arbor weather turns high-impact this afternoon as a Winter Storm Warning goes into effect from 3:00 p.m. to 10:00 a.m. Sunday. Light snow develops around midday, then intensifies late day and through the evening with gusty winds and rapidly deteriorating roads. Plow crews will be active across Washtenaw County into Sunday morning as the storm tapers to flurries.

How much snow and when it falls in Ann Arbor

Snow totals: 6–8 inches are expected in and near Ann Arbor, with locally higher drifts in open areas west of US-23.
Peak rates: 6:00 p.m.–2:00 a.m. is the most intense window, when snowfall may reach ½–¾ inch per hour, briefly near 1 inch/hour south of I-94.
Wind: Gusts 25–30 mph will blow and drift snow tonight, reducing visibility on exposed stretches.
Temperatures: Hovering near 31°F this afternoon, sliding into the 20s tonight; refreeze turns slush to ice.

Football-adjacent note: Light snow is possible around midday with worse conditions building after the game; plan extra time leaving the stadium area and expect slower highways during the late-afternoon and evening push.

Ann Arbor road impacts and travel guidance

Travel becomes difficult late afternoon and hazardous tonight as heavy snow and gusts combine with falling temperatures. Expect snow-covered lanes, expanding plow berms, and low visibility during heavier bursts—especially on I-94, US-23, M-14, and rural east–west routes.

If you must drive:

Cut speed dramatically and leave 8–10 seconds of following distance.
Use low beams in falling/blowing snow; avoid cruise control.
Give plows room—never pass on the right—and expect rolling slow-downs behind plow trains.
Carry a winter kit (charged phone, blankets, snacks, water, scraper, jumper cables).
Watch bridges/overpasses first; they ice before surface streets.

Hour-by-hour look (local time)

Time	Expect
10 a.m.–1 p.m.	Clouds thicken; light snow/flurries begin in spots; roads start to slicken.
1–4 p.m.	Snow becomes steadier; accumulations initiate on untreated surfaces; visibility dips in bursts.
4–8 p.m.	Rates increase; travel slows markedly; drifting begins on open stretches.
8 p.m.–2 a.m.	Peak snowfall with periods of heavy snow and poor visibility; blowing/drifting ongoing.
2–6 a.m. Sun	Snow gradually lightens; refreeze locks in ice.
6–10 a.m. Sun	Flurries taper; slick spots persist, especially in neighborhoods and shaded areas.

Band placement can shift totals a couple of inches neighborhood-to-neighborhood.

Sunday: cold cleanup and lingering hazards

Snow tapers to occasional flakes by mid-morning, but temperatures stay below freezing much of the day. Expect icy side streets, narrowed lanes from plow piles, and drifting in open country. Conditions improve steadily during the afternoon where sun and treatment can work, but shaded stretches may remain slick into the evening.

Early-week Ann Arbor forecast at a glance

Monday: Cloudy, cold; around 30°F.
Tuesday: Chance of light snow or flurries early; similar highs near 30°F.
Midweek: Mostly cloudy and cold; highs upper-20s to near 30°F.
Late week: A sharper chill possible; teens at night with highs in the 20s.

Practical tips for today and tonight

Park smart: Follow snow-emergency rules to keep priority routes clear.
Layer up: Wind chills slide into the teens tonight.
Shovel in stages: Clear during lulls so totals don’t compact; keep furnace and dryer vents free of snow.
Flights: Expect longer taxi and de-icing times at DTW and nearby regional airports; arrive early and travel carry-on if possible.

Ann Arbor weather turns from manageable to high-impact late this afternoon. If plans are flexible, finish errands early and stay off the roads during the evening peak. If you need to travel, slow down, give plows space, and build in generous extra time.
