Let’s stay in the Great Lakes today, with a trip to the south side of Saginaw Bay. If you couldn’t establish, that’s the Bay in Bay City.
At 218PM, ET, Bay City was reporting low clouds, fog and heavy rain. There was a smattering of showers and embedded storms from the Thumb southwest through Bay City and extending towards Lansing. This is all in association with an inverted trough dangling to the southwest of a large area of low pressure now centered in southern Ontario. Cold air is lingering to the northwest, and Bay City is riding the sharp gradient, with 50s as nearby as Bad Axe, and snow and the low 30s around Grayling AFB, east of Traverse City.
The upper level trough associated with the system is vast, and while it is contributing to the strength and broad scope of the storm, it is also going to lead to an exit plan. The storm is going to continue to taper off in Bay City overnight tonight, with a slight chance at a few flurries before sunrise on Monday. A weak embedded ridge will override the broader trough and will help usher out the last vestiges of the weekend storm by late in the day tomorrow. Overcast skies are still an unfortunate possibility on Tuesday, along with chillier air, as the new short waved ridge won’t be terribly strong.
