Winter Storm & Ice Storm Warnings have been issued across parts of southern Minnesota, where plowable snow and significant icing will be possible through midweek. Check the blog for more details. -Todd Nelson
Key Messages
- The worst conditions will be Tuesday morning and early afternoon
- Ice Storm Warning in Southern Minnesota, where more than 0.25" will be possible.
- Snowfall rates of 1 to 2 inches per hour are likely for a few hours Tuesday morning into Tuesday afternoon.
- A Winter Storm Warning is in effect for this heavy snow, with generally 6 to 10 inches expected, with isolated amounts over a foot possible
A complex and potent winter storm will cause travel impacts starting this evening, lasting through Wednesday. The worst conditions will be Tuesday morning and early afternoon. On Monday evening, a wintry mix of rain, sleet, and ice will develop across southern Minnesota. Some locations may see over a quarter of an inch of ice, and an Ice Storm Warning is in effect. On Monday night heavy snow will move into southwest Minnesota, and spread across central Minnesota and western Wisconsin Tuesday morning into early Tuesday afternoon. Snowfall rates of 1 to 2 inches per hour are likely for a few hours, which will cause significant travel impacts as visibility drops to a quarter mile at times due to the heavy snow. A Winter Storm Warning is in effect for this heavy snow, with generally 6 to 11 inches total accumulation expected, with isolated amounts over a foot possible, particularly in southwest Minnesota. Elsewhere, a Winter Weather Advisory is in effect for areas that will see a wintry mix, and less snow. Please adjust your travel plans for Tuesday if possible.
WINTER STORM WARNING REMAINS IN EFFECT FROM 9 PM THIS EVENING TO MIDNIGHT CST TUESDAY NIGHT
WHAT...Heavy mixed precipitation expected. Total snow accumulations of 5 to 9 inches and ice accumulations of around one tenth of an inch.
WHERE...Portions of central, east central and south central Minnesota.
WHEN...From 9 PM this evening to midnight CST Tuesday night.

Weather Outlook
Heavy mixed precipitation will continues across the region on Tuesday with the most significant ice found in northern Iowa, southern Minnesota and into Western Wisconsin. The heaviest precipitation will move in during the day Tuesday with areas of wet heavy snow spreading across the Twin Cities, Central Minnesota and into Wisconsin.
Twin Cities Precipitation and Temperatures.
Precipitation type and rates are listed in the chart below, which shows some of the heaviest moving in during the morning and midday hours with a potential mix during the middle part of the day as well.
Icing Totals
A band of significant Icing will develop across northern Iowa, southern Minnesota and into Western Wisconsin PM Monday into Tuesday.
- Across these areas, at least a tenth of an inch of ice will be possible.
- Areas across the southern two tiers of counties - including the Mankato and Rochester areas - could see at least a quarter to a half inch of ice.
- Areas across Iowa could see up to 0.50" of ice, which could cause power outages.
- This will cause significant concerns across the region when it comes to travel and slick surfaces. Most of this is expected to fall Monday night into Tuesday.
Snowfall Potential
A heavy band of at least 6" of snow is expected to fall from southwestern Minnesota across central Minnesota, including the metro.
- The heaviest snow is expected in western Minnesota (where icing is less likely to cut into snow totals). Areas near Redwood Falls, Montevideo, and Canby, up to a foot (or more) of snow will be possible.
- This snow will fall at a rate of 1-2" per hour at times, especially in the heavy snow band from Monday night into Tuesday, meaning keeping surfaces cleared of snow will be difficult.
- The good news is wind won't be as much of an issue vs. previous storms already this snow season, so while we could see some blowing snow it won't be a major concern.

Long Duration Snow And Ice Storm
By Paul Douglas
Another long-duration winter storm has arrived, and although it won't fit the definition of "blizzard" expect weather disruptions into Thursday morning.
Unlike our pre-Christmas blast, this is a slushy storm with temperatures in the 20s and low 30s. A surge of warmer air aloft will change snow over to sleet and freezing rain this morning. Glaze ice poses the greatest risk to the I-90 corridor of far southern Minnesota.
Some ice will reach the metro area today, but a changeover back to snow is likely, and a storm temporarily stalling out near the Minnesota-Iowa border will prolong accumulating snow into Wednesday.
How much? Enough to satisfy snow-lovers and irritate commuters. I'm still thinking 6-10" for much of the metro, but a longer period of ice will mean 3-8" far southern suburbs. Heaviest snow may fall Tuesday afternoon into Wednesday evening.
It cools off behind the storm, but I see nothing arctic. In fact, it looks downright balmy during what is usually the coldest few weeks of the year.

Climate Stories
"'Christmas comet' hurtling towards Earth for first time since last Ice Age"
"The comet orbits the Sun every 50,000 years and it should be visible to the naked eye. A green and yellow comet could soon be visible from Earth with the naked eye. If you miss it, you won't get another chance for 50,000 years: the previous time C/2022 E3 (ZTF) visited, Britain was joined to Europe and Neanderthals wandered through the last Ice Age. The long-period comet is still some distance away, out in the Corona Borealis constellation. It is predicted to reach its closest point to the Sun on January 12, 2023, and will come within 26 million miles of Earth on February 1. Astronomers have been following the comet's progress using telescopes and, more recently, it's been visible to stargazers with binoculars. By late January 2023, as the E3 comet nears Earth, it should be possible to follow its motion in the night sky without the need for equipment."
"The sky isn't just blue – airglow makes it green, yellow and red too"
"Look up on a clear sunny day and you will see a blue sky. But is this the true colour of the sky? Or is it the only colour of the sky? The answers are a little complicated, but they involve the nature of light, atoms and molecules and some quirky parts of Earth's atmosphere. And big lasers too – for science! Blue skies? So first things first: when we see a blue sky on a sunny day, what are we seeing? Are we seeing blue nitrogen or blue oxygen? The simple answer is no. Instead the blue light we see is scattered sunlight. The Sun produces a broad spectrum of visible light, which we see as white but it includes all the colours of the rainbow. When sunlight passes through the air, atoms and molecules in the atmosphere scatter blue light in all directions, far more than red light. This is called Rayleigh scattering, and results in a white Sun and blue skies on clear days."
"SCIENTISTS HAVE DISCOVERED TINY BITS OF PLASTIC IN RAINDROPS — HERE'S WHY THAT'S CONCERNING"
"They are invisible, tasteless, and come in all kinds of shapes and sizes. They can be found on land, in our rivers, and in the deepest part of the ocean. And now, they are falling from our skies. It's officially raining plastic. Microplastics, the tiny, near-invisible bits of harmful plastic that show up in our oceans, food, and bodies, have now been found in the raindrops that nourish our planet. The first discovery of microplastics in rain droplets was made in 2019 during a geological survey in Colorado by the U.S. Department of the Interior. Scientists were stunned to find microscopic fibers, beads, and shards of plastic consisting of various sizes and colors. During an interview with the Guardian, Gregory Wetherbee, co-author of the published study, said, "I guess I expected to see mostly soil and mineral particles."
