Wet, wet, wet
Inclement weather is not limited to the snow and ice. The National Weather Service said to expect "a plethora of interesting weather conditions."
Flood watches and warnings are in effect for most of Wisconsin on Tuesday, to be followed by freezing rain later in the week.
"Severe thunderstorms and even isolated tornadoes are possible across the central and southern Plains to the mid and lower Mississippi Valley," the weather service said.
By Wednesday, a squall line stretching from Memphis down through Louisiana should roll eastward through the Deep South, pushing along heavy thunderstorms, hail, damaging winds and possibly short-lived tornadoes, forecasters said.
It will be unseasonably warm in the Ohio Valley, Mid-Atlantic and Southeast, the weather service predicts.
It's not all bad
Most of the country will see rain for the better part of the week. That's good news for the Plains and mountain states, which have seen extreme to exceptional drought for months.
The snow in the mountain states will extend the fun for winter sport fans, according Coloradoski.com.
As ski season winds down, with about half of resorts already closed, some popular slopes are expecting 1 to 5 inches of fresh powder through Wednesday.
The same goes for resorts in Utah.
