A soggy Wednesday in-store, followed by colder temperatures on Thursday
Low pressure will swing through the Great Lakes on Wednesday, which will mean a rather wet day in-store - especially for the hunters on Opening Day. Temperatures will range from the upper 30s to lower 40s (areas near Lake Michigan will sneak into the middle 40s), allowing precipitation to fall in the form of rain today. A decent soaking is expected, with upwards of an inch of rain possible - especially E of I-75. Winds will be roughly 5-15 mph all day long, with the direction being out of the south this morning, shifting towards the west-northwest by the evening as the cold front passes.
Cold air advection will usher in Wednesday night (on the backside of low pressure), allowing rain showers to mix with snow, and eventually changing over to all snow by the end of the overnight period. With a northwest flow, most of the action will be lake effect. Any accumulations will be light at best, on the order of an inch or less, but could cause some roads to be slick. Most will see no accumulations overnight. Low temperatures will range from the upper 20s to lower 30s.
High pressure noses into the region on Thursday, ending any lake effect snow showers. Some sunshine will filter through the clouds, but it will be cold. Temperatures will only top out in the 30s for most, with some in the Upper Peninsula seeing highs in the upper 20s.
The tranquil/quiet weather only lasts a day, however, as the next system approaches northern Michigan on Friday. Precipitation will start off in the form of rain on Friday, then a mix on Saturday, followed by lake effect snow Saturday night and into Sunday. Timing of the changeover from rain to snow is still uncertain, but a messy weekend is looking likely.
