Big story remains the return to below normal temperatures the rest of this week into the weekend. Overnight lows will be exceptionally cold, with several locations likely falling well below freezing Wednesday night through Friday night. Daytime highs will struggle to break 50 for much of northern Michigan Thursday through Saturday. Showers come to an end this morning. May see a few light showers down near Saginaw Bay Wednesday, with some additional light scattered showers on Thursday (perhaps even mixed with snow during the morning). Otherwise, no significant storms are expected through the weekend.
Confidence is high regarding a prolonged period of cooler than normal early spring weather across northern lower and eastern upper Michigan. With this, several frost / freeze instances are on the table amid periodic rain chances… with non-zero potential for snow to mix in at times.
