While travel conditions before Thanksgiving hopefully weren't too terrible, the other side of the timeline may be a different story! A strong wave in the atmosphere will rotate around an upper-level low dropping south, increasing precipitation chances while allowing cold polar air to spill south. This will lead to multiple impacts across the country beyond Black Friday. <h1>North Side</h1>Fresh off the heels of the last system, heavy snow will accumulate across Montana and the Dakotas to end the week. Into the weekend, the storm will continue to strengthen, with models bringing shoveable snow totals across the Upper Midwest and Great Lakes.<video src="https://media.weathernationtv.com/app/uploads/2025/11/11-26_RNC RNE BAMS3K FRI TO SAT-1764208334209.mp4" controls="true" width="100%"></video>This system will also bring the coldest air of the season so far, as temperatures will struggle to warm above freezing for some throughout the weekend. Overnight lows could fall as low as the single digits in some places by Monday morning.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-26 185233-1764208362025.png"><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-26 131213-1764187939689.png">Snowfall totals look impressive, with a wide area picking up more than six inches of snow. The questions remain farther south, where rain is expected to mix in around southern Illinois and into the Midwest.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-28 073507-1764340521567.jpg"><h1>South Side</h1>Farther south, instability will grow during the afternoons as warm and humid air is pulled north from the Gulf. With strong upper-level winds and shear increasing by the weekend, strong storms will be possible out ahead of and along an advancing cold front.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-26 125600-1764187969050.png">A few storms may be possible on Friday, but models for Saturday depict the potential of strong storms, particularly across East Texas and into northern Louisiana in the afternoon hours. The Storm Prediction Center is highlighting an area from Shreveport to Houston to kick off the weekend with the best bet right now for severe storms. This comes just days after <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/north-side-of-houston-struck-by-tornado-monday">two tornadoes touched down near Houston</a>.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-28 073545-1764340551257.jpg"><video src="https://media.weathernationtv.com/app/uploads/2025/11/2025-11-28 12-57-46-1764359901356.mp4" controls="true" width="100%"></video>We'll continue to update this developing story over the following days on WeatherNation!

Powerful System Will Disrupt Travel This Weekend

While we finish our Thanksgiving food and head back home, loads of people in the Upper Midwest and Northeast are in store for a MAJOR cool down that will stretch into next week. The Climate Prediction Center has great confidence in seeing some well below-average temperatures going through early December.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-28 074118-1764340892649.jpg">But what's going on? Well, it all starts at the Polar Vortex, which typically traps arctic air where it belongs, at the North Pole. However, it's expected to weaken over the next week. As a result, frigid polar air descends south through Canada, impacting northern areas of the U.S.<video src="https://media.weathernationtv.com/app/uploads/2025/11/2025-11-26 11-29-15-1764174576719.mp4" controls="true" width="100%"></video>Now let's have a look at some of the impacts. Temperatures across the Upper Midwest will dwindle down into the single digits, with places like Minneapolis having a forecast low of four degrees on Monday.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-28 074612-1764341179950.jpg">We can also expect the winds to kick up as this arctic air makes its way down south. This could spell trouble as some of these wind chill values will likely breach sub-zero temperatures. Some of these values are getting as cold as 30 degrees below zero on Monday morning.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-28 074730-1764341257460.jpg">With such a major cool-down on the way, it's likely to shake things up in our atmosphere. Starting over the weekend, heavy snowfall and rainfall will likely impact several major cities nationwide, which could cause some issues for folks on their way back from their Thanksgiving celebrations!<video src="https://media.weathernationtv.com/app/uploads/2025/11/2025-11-28 07-57-57-1764341911220.mp4" controls="true" width="100%"></video>Make sure to stay tuned to WeatherNation, where we're going to be tracking what this system brings all throughout this weekend!

Major Cooldown in Store for the Upper-Midwest

An upper-level trough moving through the Great Lakes will head to the Northeast to bring rain, snow, winds, and lake effect snow this Thanksgiving.<h2>TIMING</h2>A low-pressure system working over the Great Lakes and northeast will continue to produce heavy snowfall, especially when our cold north-westerly winds get cranking over the warm Great Lakes that remain unfrozen.<video src="https://media.weathernationtv.com/app/uploads/2025/11/2025-11-27 08-16-49-1764256664379.mp4" controls="true" width="100%"></video><h2>AMOUNTS</h2>Some areas of the lower Great Lakes have already received more than seven inches of snowfall with this setup. <img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-28 075549-1764341761306.jpg">Winter weather alerts remain in place issued across the eastern shores of the Great Lakes through Friday. These winter alerts are for widely varying snowfall totals, with up to an additional six inches possible. Heavy snow and gusty winds could lead to whiteout conditions, where Snow Squall Warnings might be warranted. <img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-28 075650-1764341819659.jpg"><h2><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-28 075729-1764341911365.jpg"></h2>

It is that time of year again—when millions of Americans hit the road or the skies to connect with friends and family. AAA is expecting a record number of travelers this year, surpassing the record-breaking 2024. Most travelers will be hitting the road vs flying.<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/o78PUXSJCJU" start="0"></iframe></div><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-17 104347-1763401813998.png">With millions hitting the roads, traffic will be hard to avoid, no matter where you are heading. However, there will be some better times to do your traveling. AAA suggests starting the journey early, but with a reasonable night of sleep the night prior.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-17 105052-1763401888415.png">With so many traveling over the holidays, there are some favored destinations. Besides New York City, the other nine top destinations favor warm weather in late November.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-17 110215-1763402544204.png">How does this compare to previous years? With more than 6 million people expected to fly, that's a 2% increase compared to last year, but it's a more than 10% jump compared to pre-pandemic levels!<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-17 105653-1763402231681.png">

Areas in southeast Houston quickly took cover as a tornado-warned storm clipped some of the northeast suburbs. Multiple people saw this on the ground, with confirmation coming from radar that afternoon, as well. Below is the lifespan of the storms, as it went into areas close to The Woodlands and Spring.<video src="https://media.weathernationtv.com/app/uploads/2025/11/2025-11-25 08-19-33-1764084060214.mp4" controls="true" width="100%"></video>The storm left pretty extensive damage in its wake, toppling trees and damaging roofs early Monday afternoon. Far from the only storm, it was certainly the strongest.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1993122468408774968" src="https://x.com/WeatherNation/status/1993122468408774968?s=20"></div>So far, survey crews have found EF-2 damage near Klein, Texas, and EF-1 damage near Riata Ranch.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-25 163728-1764113858865.png">
