A band of higher intensity mixed precipitation has developed north of the M-46 corridor. Up to 0.03" of freezing rain has been observed in this band, with sleet and snow also reportedly mixing in. A few rumbles of thunder have also been observed in this band on the west side of the state. A steady wintry mix is expected to continue over the next several hours, with localized ice accumulation rates briefly reaching 0.05" per hour and minor sleet/snow accumulations. Slick conditions are likely to develop, if they have not already, on untreated paved surfaces. This is especially true for elevated surfaces, such as bridges and overpasses. Use extreme caution when walking or driving this morning and allow extra travel time to reach your destination.

* 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.
