A huge early spring storm expected to drop over a foot of snow in far northwest Wisconsin could cause big problems other than snow, with more flooding in the forecast.
The National Weather Service has issued winter storm warnings and flood warnings throughout the state, with the storm expected to produce a messy mix of rain, snow, sleet and freezing rain in south-central Wisconsin.
There's also a chance for thunderstorms Thursday afternoon and evening, with an isolated severe thunderstorm possible as well, producing large hail and winds gusting up to 60 mph.
The far southern tiers of counties in Wisconsin will be spared the big snows forecast for northern and central parts of the state, but travel conditions to counties north of Madison to the east could be bad Wednesday night into Thursday morning.
A winter weather advisory has been issued for nine counties north of Dane County, including Columbia, Dodge and Sauk Counties, with 1 to 3 inches of slushy wet snow expected, and winds gusting up to 35 mph could make for treacherous travel.
For anyone venturing to the far north, keep abreast of changing and challenging weather conditions.
In the far northwest, Douglas, Burnett and Washburn Counties could see up to 16 inches of snow and winds gusting up to 50 mph from early Thursday to early Friday.
A flood watch is in effect on Lake Superior for Douglas County, with crashing waves containing large chunks of ice possibly causing damage to the shoreline.

For the Madison area, a mix of rain and snow will spread across the region from mid-morning Wednesday to mid-afternoon.
"Slushy accumulations of several inches are possible on grassy and colder elevated surfaces," the Weather Service said.
This slush will morph into a more wintry mix Wednesday night to the west and north, while we can expect mostly rain in the overnight hours here.

Rain is expected to continue Thursday and Thursday night before dying out on Friday.
Rain is not good for area streams, already filled to the brim and overflowing in some areas.
Flood warnings remain in effect on the Rock River in Rock County, the Fox River in Green Lake County and all along the Mississippi River.
Ground has thawed but is saturated, so rain has very little option but to flow to waterlogged streams, exacerbating the flooding.
