Special Weather Statement

Special Weather Statement issued January 14 at 4:55AM CST by NWS Green Bay WI

Jan 14, 4:55 AM → Jan 14, 9:00 AM

Rain that changed to snow earlier this morning, followed by
temperatures sharply falling into the 20s will result in slippery
conditions on untreated roads, parking lots, and sidewalks for
the morning commute.

If you are traveling early this morning, expect slippery or even
icy conditions in some areas. Build in extra time to reach your
destination, and increase the distance between you and vehicle
ahead of you in case you need to suddenly stop.
