Winter Weather Advisory
* WHAT...Freezing rain expected. Total ice accumulations will range
between one tenth of an inch to just below a quarter inch.
* WHERE...A portion of southeast Michigan.
* WHEN...Until 4 PM EST this afternoon.
* IMPACTS...Plan on icy roads and surface conditions. The hazardous
conditions will impact the morning commute and holiday travel.
* ADDITIONAL DETAILS...The higher end ice accumulation potential to
or above two-tenths of an inch will be favored around the M-59
corridor through the I-69 corridor, and north through Saginaw,
Tuscola, and Sanilac Counties. In addition to freezing rain, some
mixing of sleet remains possible across the northern Tri-Cities
and northern Thumb, with sleet accumulation potential to a
half-inch or less. Locations towards Metro Detroit and the Ohio
border have the best chance of temperatures rising above freezing
by the afternoon.
From: Dec 26, 2025 09:14

Special Weather Statement
Freezing rain will continue to expand across Southeast Michigan
early this morning. Once the freezing rain begins, it will persist
off and on through the morning. Untreated paved surfaces will
quickly ice over this morning. This will be most notable on
bridges and overpasses. Drivers are urged to use extreme caution
on the roads this morning.

the Tri Cities and northern Thumb. More of a pure freezing rain
scenario is favored for the I-69 to M-59 corridors which also has
the best chance of higher end icing totals. Locations toward metro
Detroit and the Ohio border have the best chance of temperature
rising above freezing by afternoon.
