Sloppy, complex storm system will leave snow, rain and a mix across portions of Minnesota Tuesday

"It's just a sloppy system and that's the problem," says WCCO-TV Chief Meteorologist Chris Shaffer

If you're looking for a simple forecast with clear snow totals on Tuesday? Good luck. Because this is a tricky one, a forecast even the National Weather Service calls "complex."

But for most of Minnesota, some form of nasty winter weather is coming. Here's what we know:

Your experience will really depend on where you are, even in the Twin Cities metro.

"This one, the snow totals aren't so high," says WCCO-TV Chief Meteorologist Chris Shaffer. "It's just a sloppy system and that's the problem, where there's gonna be a lot of phase changes. If you look at radar right now, the storm is still over North Dakota and it looks like a slice of Neapolitan ice cream coming in at an angle with snow on the northeastern end, the kind of strawberry in the middle, that's the mixed precipitation. And then the rain on the southern flank, and it's gonna keep coming down at that angle. Typical Alberta Clipper system style."

Where you get the snow, the mix, and the rain is going to have everything to do with the snow amounts - eventually. For now, it won't be an issue, right through midday in the Twin Cities.

"There's a little mist here and there, but things will be fine," says Shaffer. "Once the snow starts early this afternoon, there'll be a rapid accumulation on the roadways. In the metro, there could be a little mixing in with some rain at times and then going back to snow. We're right on that middle ice cream Neapolitan line that we'll see kind of both of this. North, if you live in St. Cloud, Little Falls, Cambridge, New Richmond, Wisconsin, even, it's all snow for you. You could see 4 to 8 inches of snow."

There is a sharp gradient of snowfall totals and it will mainly land along Interstate 94. North of that, more snow. South of that, more of a mix.

"And then in the southwestern parts of the state heading toward Hutchinson, even, Faribault, Mankato, maybe 1 inch, maybe 2," Shaffer predicts. "Not much because you'll see more of that rain coming through."

Shaffer says the Twin Cities should see more in the 2-4 inch range of snow totals. There might be some rain mixed in, but the bulk of the metro is really on the southern edge of mostly snow.

"With 2 maybe down in Shakopee, 4 inches as you head toward up to say Scandia, Anoka, Ramsey, all the northern tiers," he told Vineeta Sawkar on the WCCO Morning News.

It'll be a sharp cutoff, directly over the Twin Cities, as to where the heaviest snow will fall on Tuesday and Wednesday.

That afternoon commute on Tuesday could be a doozy. And wind will become a problem, even in the metro with gusts approaching 40 mph. To the west and north, those winds will be even stronger. In southwest Minnesota, ground blizzard conditions will be possible, especially in the overnight hours.

"The temperatures drop off quickly as that snow moves out," Shaffer adds. "Your commute home later is going to be slower. The roads will be in tougher shape. One good thing with the warmer temps, the MnDOT plows and the salt and chemicals, they go to work rapidly. By tomorrow morning, I would expect a longer commute still, just residual stuff. 23 is the high. It's going to be very windy overnight and during the day tomorrow."

That's just the appetizer because the cold is going to get very real heading towards the weekend according to Shaffer.

"We're talking about highs Friday and Saturday in the single digits," he says. "Likely dipping to the double digits below zero Friday night and Saturday night, which means if you're an early riser Saturday and Sunday, it's gonna feel like 20 to 25 below."
