Honestly, if you’ve lived in the Twin Cities for more than five minutes, you know the drill. We start January with a little bit of false hope—maybe a few days in the 30s, some sunshine, people wearing "light" hoodies instead of the heavy-duty Arctic parkas. But as we look at the 20 day forecast minneapolis mn, that honeymoon phase is officially over. We are staring down a serious stretch of subzero lows and wind chills that’ll make you question every life choice that led you to live in a place where the air hurts your face.
The current setup is basically a textbook "winter reality check." After a start to the month that ran nearly 9 degrees warmer than average, the atmosphere is finally making up for lost time. A series of clippers and a strengthening polar vortex are essentially opening the floodgates for Canadian air to pour straight down I-35.
What the 20 Day Forecast Minneapolis MN Really Looks Like
If you’re looking for a silver lining, you won’t find it in the thermometer this week. Today, Saturday, January 17, we're struggling to hit a high of 11°F. It’s cloudy, it’s gray, and there’s a biting northwest wind at 14 mph. Tonight? We’re dipping down to -1°F. And that’s just the appetizer.
By Monday, January 19, the high is projected to be -1°F. Not the low—the high.
The overnight low for Monday is looking like -11°F. When you factor in the wind, it’s going to feel significantly worse. Most of next week follows this pattern: highs in the low teens, lows consistently below zero. We’re looking at -8°F on Tuesday night and another -14°F dip by the following weekend. Basically, if you have a remote starter for your car, now is the time to make sure the batteries are fresh.
The Science Behind the Deep Freeze
Why is this happening now? It’s not just "bad luck." Meteorologically, we are seeing the impacts of a negative Arctic Oscillation (AO). When the AO is negative, the jet stream gets "wavy," allowing that freezing air trapped in the Arctic to spill southward into the Midwest.
National Oceanic and Atmospheric Administration (NOAA) experts like Brad Pugh have been watching the Madden-Julian Oscillation (MJO) shift into phases 6 and 7. This setup almost always favors anomalous cold across the eastern two-thirds of the U.S., with Minnesota being right in the crosshairs. While much of the country has been mild, we are one of the few spots where below-average temperatures are predicted to stick around through the end of January and even into early February.
Precipitation and Snow Scenarios
Snow-wise, it’s not a "one big storm" situation. Instead, we're seeing "clippers." These are fast-moving systems that drop 1-3 inches at a time but happen every couple of days.
- Sunday, Jan 18: 35% chance of snow showers with a high of 13°F.
- Wednesday, Jan 21: Light snow expected with a 20% chance.
- January 29-31: Long-range models from sources like the Farmers' Almanac are hinting at a more significant snowstorm to cap off the month.
It’s the kind of snow that’s light and fluffy because it’s so cold—it doesn’t pack well for snowmen, but it’s a pain to shovel when the wind keeps blowing it back onto your driveway.

Living Through the Minneapolis Freeze
The reality of a 20-day stretch like this is that it changes how the city functions. You start seeing "ice fog." You notice the steam rising from the Mississippi River because the water is technically warmer than the air.
If you're heading out to the Chain of Lakes or trying to get some miles in on the Grand Rounds, you need to be smart. Frostbite can happen in under 30 minutes when wind chills hit -20°F. Experts recommend the three-layer rule: a moisture-wicking base, an insulating middle (think wool or fleece), and a windproof outer shell.
Don't forget your pets, either. If it's too cold for you to stand outside in your bare feet for two minutes, it's definitely too cold for your dog.
Actionable Steps for the Next Three Weeks
Since we know the cold is staying put, there are a few things you should actually do instead of just complaining about it on Reddit.
- Check Your Tires: Air pressure drops significantly when the temp craters. If your "low tire" light isn't on yet, it probably will be by Monday morning.
- Humidity Management: With the heat running constantly, indoor humidity will tank. Aim for 30-35% to avoid itchy skin and static shocks, but don't go higher or you'll get ice buildup on the inside of your windows.
- Emergency Kit: Make sure you have a blanket, a portable charger, and some extra gloves in your car. If you slide off the road in -10°F weather, "waiting for a tow" becomes a survival situation very quickly.
- Pipe Protection: If you have an older South Minneapolis bungalow with pipes on exterior walls, keep those cabinet doors open to let the room heat reach the plumbing.
Winter in Minnesota is a marathon, not a sprint. We’ve got about 20 days of grit ahead of us before we can even think about a February thaw. Stay warm, keep the salt handy, and remember—at least there are no mosquitoes.
