A snowstorm will move quickly across Wisconsin on Sunday, delivering just enough wet, heavy snow to cause slippery travel conditions, according to forecasters.
Light snow will overspread the area late Sunday morning and early Sunday afternoon, exiting by late Sunday evening, with 1 to 3 inches of wet, heavier snow expected all across southern Wisconsin, National Weather Service lead forecaster Jaclyn Anderson said.
No more than 3 inches is forecast anywhere in Wisconsin, with the lowest totals in northwest Wisconsin.
The snow will develop Sunday as low pressure tracks from Missouri into Illinois, moving farther to the east Sunday night, AccuWeather said.
The storm comes with a dramatic change in the weather pattern that will have temperatures returning to normal ranges, AccuWeather said.
"The atmospheric traffic jam that was contributing to a major buckle in the jet stream will break down in the coming days," AccuWeather senior meteorologist Brett Anderson said. "As this (pattern shift) happens, the polar vortex is expected to retreat to northwestern Canada and allow a milder Pacific air to flow across much of the U.S. and southern Canada from this weekend through next week.”
Across the northern Plains and Upper Midwest, cities such as International Falls, Minnesota, and Grand Forks, North Dakota, that saw subzero temperatures from Feb. 6 through Feb. 14 will get above freezing with the pattern change.
