High pressure over the Canadian Shield slowly relinquishes its hold over Upper Michigan Tuesday night, resulting in skies going from mostly clear to mostly cloudy, especially over the western half of the region with a scattered pop-up of rain showers and thunderstorms. The Northern Plains system responsible for the showery change spreads rain and thunderstorms to the eastern counties by Wednesday’s end.

Warm air ridging continues undisturbed over the U.P. through Friday, with fewer coverage of rain and thunderstorms as high pressure rebuilds over the region.

Another Northern Plains system spreads rain to Upper Michigan Mother’s Day weekend. Another round of showers comes early next week by way of a Canadian Prairies clipper system that also brings a brief cooling trend to the region for mid-May.
