It's going to be a very dry end to the week for Upper Michigan, as well as a rather cool one. Temperatures have fallen down below average today and will be only a bit warmer tomorrow.
Saturday, however, will bring about more significant changes.
While it doesn't look like much in its present state, a low pressure system will gather steam through the day Friday and make a charge into the Great Lakes region by early Saturday morning. What makes this storm so interesting is the myriad of precipitation it will bring to Upper Michigan.
Relatively warmer air (compared to cold air behind it) will wrap around the north side of the storm as it pushes just to the south of the U.P. This means that while the northwestern U.P. may remain all snow, most locations over the eastern U.P. will see any initial snowfall changing to rain. Central U.P. residents will likely see a healthy mix of both, which will drastically limit any accumulations. At this point, amounts are hard to pin because of the uncertain nature of the rain/snow line.
By Sunday, any lingering precipitation will likely change to snow as it turns colder and more blustery. The problem for all you snow-lovers, though, is that the heaviest precipitation will have ended, also limiting accumulations.
