Much of Wisconsin is expected to have a 'long duration snow event' starting Tuesday night
Much of Wisconsin is forecasted to have a "long duration snow event" from Tuesday through Thursday, according to Taylor Patterson, meteorologist for the National Weather Service in Sullivan.
The snow will transition into mixed precipitation in southern parts of the state, including the Milwaukee area, on Wednesday, but will turn back into snow again Wednesday night into Thursday.
Here's what we know so far.
When and where will the snow start?
The snow is expected to start statewide Tuesday night into Wednesday morning, Patterson said. It will move in from west to east.
How long will it snow?
Snowfall will be ongoing through Thursday in central and northern Wisconsin.
On Wednesday, a low-pressure system will move in from the south, which will bring another push of moisture and warmer temperatures. This will cause the snow to transition into mixed precipitation in southern Wisconsin, from around Sauk, Columbia, Dodge and Ozaukee counties and south, Patterson said.
The weather service is working on pinning down exact precipitation types, Patterson said, but freezing rain is a possibility.
Wednesday night into Thursday, temperatures will start to cool again, and the mixed precipitation will turn back into snow.
Too early to tell snow total amounts, but Wednesday night is expected to have the highest rates of precipitation
"There's still a lot in play here as far as exact amounts and totals," Patterson said.
The highest rates of snowfall or mixed precipitation are expected to occur on Wednesday night, she said.
When will the snow stop?
The snow is expected to taper off Thursday, according to Rebecca Hansen, meteorologist for the NWS in Sullivan.
'Quick-hitting system' could bring light snow Friday night
A "quick-hitting system" with lighter amounts of snow could occur Friday night across much of the state except the far northwest, Hansen said. It's expected to be "nothing significant."
