A winter storm will develop on Monday over Wisconsin. Initially precipitation in the form of rain will move in from the into portions of eastern/NE Wisconsin(arriving from the east). By mid morning hours rain will begin changing over to snow; perhaps heavy for some. By late morning mostly snow will be falling over Wisconsin. During the afternoon hours snow will move out of the north into southern Wisconsin. Snow ends late Mon PM or early Tues AM. See forecast below for details!
This is an usual storm track and part of a larger system with a complex evolution. Seems to be the theme here in 2019(soon to be 2020). The storm for Monday will strengthen/reorganize over northeast Wisconsin which is further east compared to the weekend storm that brought heavy rain to Wisconsin. All things considered this lowers the overall predictability thus some uncertainty remains regarding where exactly the heaviest snowfall amounts will be located.
SOUTHEAST WI - I trimmed snow totals back along the lakeshore and Milwaukee. Inland I think 1-2" will be possible by early Tuesday AM for places like Madison, Hartford, and Menominee Falls.
NORTHEAST WI - Large split in models between 3-6" in southern portion and 6-12" in the far northeast(i.e Marinette, Sturgeon Bay, Iron Mountain and even over towards Rhinelander. It's likely that a heavy band will occur in the area...the exact location of which is not totally set in stone. I did my best to constrain the higher totals further north but had to respect the model average. Should be interesting!
UPPER MI - Heaviest snow amounts will be in the lake effect belt, probably spots well over 1ft(in addition to what has already fallen). For the rest of the UP; I wanted to pull that 6-12" over to Door County. Just the way that SE -> NW orientated snow band - changing over from rain - lays out.
