...Late season wet and heavy snowfall possible over northwest Upper Michigan...
A broad low pressure system moving east out of the northern and Central Plains on Thursday will spread precipitation across Upper Michigan late Wednesday night through Friday morning. While confidence is high that there will be precipitation...whether this will be in the form of rain or snow remains difficult to pin down. At this time...it appears a mix of rain and wet snow will overspread Upper Michigan west to east on Thursday but then transition to mainly snow over much of northwest Upper Michigan by early evening. The wet snow may then fall heavy at times on Thursday night...especially over the higher terrain...before the precipitation diminishes early on Friday morning.
At this time...the best bet is the heaviest snow will fall over the higher terrain of the Keweenaw peninsula...where the current forecast shows as much as 6 to perhaps 8 inches accumulating through Friday. Over the rest of the higher terrain northwest of a line from about Marquette to Crystal Falls...2 to 5 inches of wet snow appears likely. The wet...heavy nature of the expected snow will make shoveling and snow removal very difficult.
Given the large uncertainty on the precipitation type that will accompany the passage of this low pressure system...stay tuned to later forecasts and possible advisories or warnings for this evolving early Spring winter storm.
