During the winter months, many of us are no strangers to chilly temps and downright unbearable cold. However, Mother Nature often times likes to bend the rules a bit. A weakening polar vortex is likely to spell trouble for the High Plains late this week. What is the polar vortex? You can think of it as a permanent area of low pressure that stays at the Earth's poles! A strong polar vortex does a good job of keeping that arctic air where it needs to be. However, during the winter months, a weak polar vortex can allow some of that air to sink into the U.S.<img src="https://media.weathernationtv.com/app/uploads/2026/01/web1-1768833952146.png">Cold weather alerts have been issued for these areas for the end of the week, with dangerously cold temperatures in the forecast.<img src="https://media.weathernationtv.com/app/uploads/2026/01/Screenshot 2026-01-20 152112-1768947676564.png">This polar air will have some pretty hefty impacts across the High Plains. Thermometers will read values well below zero, but once you factor in that wind, the wind chill will take you down to 30+ below zero in places like the Twin Cities and Bismarck. But it gets worse. Let's say you find yourself in northern Minnesota. Roseau could see wind chill values as low as 49 degrees below zero! Downright dangerous cold!<img src="https://media.weathernationtv.com/app/uploads/2026/01/NORHTEN MI-1768964625715.png">Meteorologist Alana Cameron spoke to the National Weather Service in Duluth, MN, about this upcoming cold:<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/8gzSxDH1u5I" start="0"></iframe></div>These temperatures will also seep into the northeast, bringing wind chill values out in New York City down to 3 degrees below zero Saturday morning!<img src="https://media.weathernationtv.com/app/uploads/2026/01/Screenshot 2026-01-20 152138-1768947702486.png">Reminder to keep yourself bundled up to the max heading into the late week! Frostbite can occur in mere minutes when the wind chill values get below -42 degrees! It's important to limit your skin exposure to the elements during this time as well!<img src="https://media.weathernationtv.com/app/uploads/2026/01/web8-1768835305901.png">Make sure you stay tuned to WeatherNation for the latest on these temperatures, and how we can keep YOU safe through these frigid temperatures!

The snow that fell in the south has barely melted and we're already moving onto the next chance? You're probably already seeing people on social media posting about the threat, so let's talk about it.Winter storm watches have been getting issued in advance of this winter storm with varying totals, but generally ice up to .2" and snow up to 4" can be expected.<img src="https://media.weathernationtv.com/app/uploads/2026/01/Screenshot 2026-01-20 151932-1768947581662.png">Meteorologist Jackie Brown spoke with the National Weather Service in Norman, Oklahoma, about this upcoming winter storm.<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/878G77ma2i0" start="0"></iframe></div><h1>SETUP</h1>Air that's normally locked up around the poles looks to break off from the region. From there, it will slide southward, invading the southern states. Sub-freezing temperatures will settle in behind this Arctic front, potentially as early as Friday. At the same time, a disturbance will roll onshore from Baja California, providing the lift and moisture needed to cause problems.<img src="https://media.weathernationtv.com/app/uploads/2026/01/Web1-1768905366696.png"><h1>TIMING</h1>This is where we could see the trickiest part of the forecast, not named precipitation type. Models have been a little all over the place, pushing the cold air in, with some as early as Friday afternoon. If that pans out, the Friday evening's commute could be in some trouble. Saturday feels like a safer bet to see trouble, especially in the morning.<video src="https://media.weathernationtv.com/app/uploads/2026/01/2026-01-20 03-36-25-1768905407697.mp4" controls="true" width="100%"></video><h1>UNCERTAINTY</h1>There's a lot riding on when the front moves in. The overall picture of what looks to be shaping up is fairly consistent. Rain turning into freezing rain before becoming sleet and snow seems to make the most sense, given how the setup looks.<img src="https://media.weathernationtv.com/app/uploads/2026/01/Screenshot 2026-01-19 080851-1768835338441.jpg"><h1>WHAT YOU SHOULD DO</h1>With this likely not moving in until at least Friday afternoon, there's plenty of time to prepare. Know what your plans are on Friday and if they're negotiable. This far out, we still only look at forecast trends, before honing in on specific totals. Make sure you stay tuned to WeatherNation for all the latest info on what you can expect towards the end of this week.<img src="https://media.weathernationtv.com/app/uploads/2026/01/Screenshot 2026-01-20 152002-1768947607366.png">

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

Sub-freezing temperatures made their way into the South and Southeast once again Sunday into Monday, with lows in the 30s as far south as South Florida! Temperatures Monday morning (above) dropped down to 25 for Jacksonville, FL and 28 in Atlanta, GA.These chilly temps were cold enough to stun cold-blooded Iguanas, which are an invasive species.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2012155375894806776" src="https://x.com/WeatherNation/status/2012155375894806776"></div>Freeze Alerts remain through Tuesday morning. These are typically issued at the start or end of the growing season, but in the case of Florida, the growing season is a little more ambiguous. These have been issued because frost and freeze conditions could kill crops and other sensitive vegetation, and possibly damage unprotected outdoor plumbing.<img src="https://media.weathernationtv.com/app/uploads/2026/01/Web1-1768904370694.png">Temperatures by mid to late week will return closer to normal for overnight lows.<img src="https://media.weathernationtv.com/app/uploads/2026/01/Web2-1768904517103.png">

SOUTH - Rounds of cold arctic air have been pushing across the South. As we head into the weekend, another frontal system will draw in just enough cold air and encounter just enough moisture to bring the potential for snow to the South. Totals should be on the lighter side, but some areas could see 1-3" stick.<img src="https://media.weathernationtv.com/app/uploads/2026/01/web1-1768735519341.png">A winter weather advisory has been issued from eastern Alabama into southern Georgia, even a few into the northern Panhandle of Florida! Snow could accumulate in these areas, including interstates like I-75, I-16, and I-20.<h2>Forecast</h2>The NBM (National Blend of Models) shows the probability of snow across the South. Currently, the best chances are from southeastern Alabama up through the Carolinas.<video src="https://media.weathernationtv.com/app/uploads/2026/01/2026-01-18 06-27-17-1768735661002.mp4" controls="true" width="100%"></video>Moisture is likely to begin as rainfall on Saturday before transitioning to snow into late Saturday night, but more likely Sunday morning.
