Late Season Snowfall over western Upper Michigan late today into Friday

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, a mix of rain and wet snow is expected to overspread Upper Michigan west to east on Thursday but then transition to all snow over much of northwest Upper Michigan by early evening. The wet snow is expected to fall heavy at times on Thursday night, especially over the higher terrain, before the precipitation diminishes early on Friday morning.
 
With confidence increasing in regards to moderate to heavy snowfall over the Keweenaw Peninsula, a Winter Storm Watch is in effect Thursday afternoon through Friday morning. Snowfall amounts there are forecast to be in excess of 8" through Friday.
 
Over the rest of the higher terrain northwest of a line from about Marquette to Crystal Falls, 3 to 6 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 additional advisories or warnings for this evolving late-season storm, which will be posted on our Winter Monitor page.
