MICHIGAN — High pressure brought mostly sunny skies and a return to spring-like temperatures across Michigan on Tuesday April 21, 2026, after the previous day’s taste of late-winter conditions. Highs were expected in the 60s statewide with low 70s possible south of I-96, while winds gusted from 20 to 40 mph across the Lower Peninsula and a short window for pop-up thunderstorms developed along and south of I-94 during the evening hours.
Spring Temperatures Return Statewide — 60s to Mid 70s Across Michigan Tuesday
The temperature map for Tuesday showed a clear warming trend from north to south across Michigan. The Upper Peninsula ran cooler with Houghton at 44, Marquette at 51, and Iron River at 58, while the Lower Peninsula warmed significantly with Grand Rapids at 71, Lansing at 72, Kalamazoo at 72, Holland at 72, and southern communities including Adrian at 75 and Coldwater at 74 leading the state.
Central Lower Peninsula communities including Flint at 69, Saginaw at 68, Mt. Pleasant at 68, and Cadillac at 66 all saw comfortable spring readings through the afternoon, marking a sharp and welcome contrast to the previous day’s late-winter feel across the state.
Pop-Up Thunderstorms Possible Along and South of I-94 This Evening — Small Hail Cannot Be Ruled Out
A short window for pop-up thunderstorm development was forecast for Tuesday evening along and south of the I-94 corridor. The thunderstorms were not expected to be severe in nature, but forecasters noted that some small hail could mix in within the most powerful updrafts during the evening storm window.
Storms were expected to form and then move southward into Indiana as the evening progressed, limiting the duration of the thunderstorm threat across the affected Michigan communities south of I-94.
Winds Gusting 20 to 40 MPH Across the Lower Peninsula — Warmer Days Ahead Wednesday and Thursday
Winds were expected to gust between 20 and 40 mph across the Lower Peninsula throughout Tuesday, adding a breezy element to an otherwise pleasant spring day across the state. The gusty conditions were the most notable weather concern for the daytime hours ahead of the evening thunderstorm window.
Looking ahead, forecasters confirmed temperatures would continue climbing through Wednesday and Thursday, with winter jackets able to go into the closet until at least the weekend for most Michigan residents outside of the cooler lakeshore communities.
