Parts of Wisconsin could see snowstorm later this week, potentially heavy snow for some areas

Parts of Wisconsin could see a snowstorm this week, with potentially heavy snow for some areas if two storm systems come together, or less if they stay separate, according to forecasters.

If there is a big storm, the bullseye will be in central to northern Wisconsin, AccuWeather said, with southern Wisconsin likely to see plenty of rain and possibly some mixed precipitation.

A far-reaching storm system will first bring much-needed snowfall across the Sierra Nevada early in the week, before slowly tracking through the intermountain West on Wednesday, while the Plains and Midwest ride a temperature rollercoaster.

Temperatures in places like Rapid City, South Dakota and Denver will soar into the middle 50s to the middle 60s Wednesday ahead of the storm, then plunging.

"At this time, it appears the best chance for heavy snow will be across much of Colorado, Wyoming and South Dakota as the storm emerges from the Rockies," said AccuWeather Meteorologist Courtney Travis.

Meanwhile, a quick-moving storm in southern Canada could interact with the first storm moving across the Plains, possibly changing the impacts and location of the heaviest snow, AccuWeather said.

AccuWeather meteorologists believe it is more likely the storms remain separate. This would direct the swath of snow farther south in the Upper Midwest, and make the snow in that zone less intense than that of the Plains.

However, If the storms phase together, more snow and wind will spread closer to the Canadian border, with blizzard conditions possible in parts of Minnesota and central to northern Wisconsin late Thursday into Thursday night.

The actual temperatures Thursday night and Friday night from Denver to Green Bay is expected to dive down into the teens and lower 20s.

In the wake of the storm, conditions will calm down through weekend across the Plains and into the Midwest as an expansive area of high pressure sinks southward from Canada.

In Madison on Monday, look for mostly cloudy skies, a high near 42 and south winds at 5 to 10 miles per hour turning out of the southwest in the afternoon, the National Weather Service said.

There’s a 20% chance for rain overnight as the low falls to around 29, with Tuesday’s forecast featuring sunny skies, a high near 46 and northwest winds around 10 mph.

As the storms begin move in, there’s a 40% chance for rain and snow Tuesday night; a 90% chance for rain Wednesday, with possible totals of a quarter- to half-inch; a 40% chance for rain Wednesday night; a 90 percent chance for rain Thursday and again Thursday night, with possible totals of a quarter- to half-inch both periods; and a 40% chance for rain, mixing with snow after 9 a.m., on Friday; before quiet weather moves in.

Skies over Madison should be cloudy Wednesday and Thursday, mostly cloudy Friday, mostly sunny Saturday, and sunny Sunday, with highs near 44, 54, 40, 34 and 41, and lows Tuesday night through Saturday night around 32, 39, 33, 18 and 19.

27 Storm Track meteorologist Max Tsaparis forecasts a chance for a morning flurry or sprinkle Monday, a light mix to rain developing late Tuesday night, changing to rain Wednesday night, scattered rain Thursday, rain to light snow Thursday night, and a little light snow Friday, mainly in the morning.

Tsaparis said highs Monday through Sunday should be near 41, 46, 43, 46, 36, 34 and 42, and overnight lows around 28, 33, 35, 30, 16 and 19.
