Significant early season winter storm

(November 29, 2025) – A Winter Storm Warning will be in effect through Sunday morning for the entire area (except Allen County, OH where a Winter Weather Advisory will be in effect). Widespread snow totals of 6-12” are expected.

Key Messages:

  • A Winter Storm Warning will be in effect through Sunday morning for the entire area (except Allen County, OH where a Winter Weather Advisory will be in effect). Headlines persist through the day Sunday downwind of Lake Michigan where lake effect snow persists.
  • Widespread snow totals of 6-12″ are expected.
  • The heaviest snowfall is expected from 3 PM to 10 PM EST today. Snowfall rates over 1″ per hour are possible.
  • Travel will be significantly impacted along the I-69, I-80/I-90, I-94, and US 30 corridors this weekend.
  • Widespread snow ends early Sunday but lake effect continues through Sunday, causing impacts to linger.

Snow Amounts

  • Highest snowfall amounts of 8-12″ are likely for southwest Michigan and northern Indiana (this includes system snow Saturday night and lake effect snow Sunday).
  • Locally higher amounts over a foot possible.
  • A swath of 5-9″ is likely for the I-69 corridor.
  • South of US 24, drier air and a rain/snow mix could cut down on snow totals.

Snow Character

  • Snow will begin as a wet/heavy snow (ratios 10:1) and will transition to a more “drier” snow on Sunday (ratios 15:1)
  • Due to the heavy, wet nature of the snow, compaction will occur quickly today and tonight.
