Arctic air is set to take a deep dive into the Southern United states. Millions of Americans will be impacted by these cooler temperatures this weekend through next week. This cold outbreak is being driven by a strong upper-level low dipping southward from Canada, allowing frigid polar air to surge into the central and eastern portions of the country. This low will also help to drive multiple cold fronts across the country. There will be widespread subfreezing temperatures overnight, with many regions experiencing daytime highs that will struggle to climb above the freezing mark.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 072835-1762612121598.jpg">In some areas, temperatures could run 20 to 30 degrees below average, especially across the Plains, Midwest, and Great Lakes region.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 072933-1762612178062.jpg">Monday and Tuesday's lows will plummet into the 20s, 30s, and 40s all the way to the Central Gulf Coast States and Florida. Numerous frost and freeze alerts will be issued ahead of the coldest air - protect sensitive plants.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 073012-1762612288445.jpg">Farther south, the cold air will bring the season’s first frost and freeze to areas that typically remain mild into late fall. The combination of Arctic high pressure and strong cold advection will make the air feel even colder, with wind chill values dipping into the single digits in northern states.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 073032-1762612306042.jpg">This early blast of winter is a reminder that the transition from autumn to winter can happen abruptly when large-scale atmospheric patterns align. People should prepare by checking heating systems, protecting exposed pipes, and dressing in multiple insulating layers to guard against hypothermia and frostbite. The cold pattern may linger for several days before a gradual moderation occurs as the upper-level flow begins to flatten and the jet stream retreats northward.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 073339-1762612427458.jpg">Get forecast details for your section of the country with our regional forecasts, which air at :10, :30, and :50 past the hour from east to west.

Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

Lake effect snow season has arrived, with heavy snow expected this weekend into early next week! Watches and advisories have been issued on the southern sides of Lake Superior and Lake Michigan, with alerts around Lakes Erie and Ontario likely to be issued soon as well. Snow in these areas could top 8-12" on some locations, with heavy snowfall rates likely reducing visibility at times, making travel very difficult.<h1><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 055534-1762606642794.png">How Lake Effect Works</h1>Water has a much higher heat capacity than air, meaning it takes more time to warm up and cool down. This leads to "mild" water temperatures in the Great Lakes while the air overhead can be much cooler. As the cold, dry air moves over these areas, it's able to evaporate moisture from the lakes until it condenses into clouds and precipitation before falling out over land. Typically, we need at least a 13° F difference between the lake water and the air aloft (around 1500 m, or 4500-5000 ft) for lake effect snow to form. This weekend, the difference will be close to 35-45°! <h1><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 060323-1762608655882.png"><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 060332-1762608670553.png">Forecast</h1>Lake effect snow begins to develop late Saturday as the cold air begins to filter farther south with stronger northerly flow. Sunday will see additional lake effect snow develop as the cold continues to spill in, eventually turning mixed rain and snow showers to all snow. As the winds shift slightly from the NNE late Sunday into Monday, Chicago could see some intense lake effect snow drift over downtown from the lakeshore. This is completely dependent on a shortwave around the upper-level low providing those NNE winds, so if that shifts a bit, Chicago may get missed. Other areas more certain to see some heavy accumulations include locations on the SSE sides of the lakes, and on the SE side of Lake Ontario. Winds shift back to the North and NW by Monday, bringing the heavier snow into Ohio, Pennsylvania, and New York.<video src="https://media.weathernationtv.com/app/uploads/2025/11/2025-11-08 06-03-56-1762608689758.mp4" controls="true" width="100%"></video>Impacts to travel can be expected, especially along the I-90 corridor where major impacts are possible in NW Indiana. Make sure your vehicle is ready for winter travel with some good tread on your tires and a winter driving kit.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 060346-1762608655878.png">You can catch the latest forecast for the Great Lakes anytime by using the WeatherNation app to view the Central Regional Forecast.

An Alberta Clipper moving through the Midwest on Saturday will usher in colder air with a mix of rain and snow. Behind the clipper, MUCH colder air develops with single digit wind chills possible. Before the much cooler air arrives, temperatures will be hovering near freezing Saturday for some areas, leading to light snow accumulations. The Siouxland area is under winter weather advisories for up to 4" of snow, while areas in the Black Hills of South Dakota could see up to 6 inches.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 050750-1762603780662.png">Moderate rainfall and lighter snow will continue to drift east with the low pressure system into Saturday afternoon, turning to mostly rain as the sun is up. Cooler temperatures lead to snow redeveloping late this evening into Saturday morning from Illinois through Michigan.<video src="https://media.weathernationtv.com/app/uploads/2025/11/2025-11-08 05-34-32-1762605301251.mp4" controls="true" width="100%"></video><h1>Winds &amp; Temperatures</h1>Afternoon highs will struggle to warm out of the 30s for most areas impacted by the precipitation. Keep in mind, another feature of quick systems like these is gusty winds. With wind gusts 20-30mph, it's going to feel even cooler. <img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-07 132101-1762546876568.png">Much colder air is expected Sunday into next week as an <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/record-warmth-possible-from-nevada-to-texas">arctic blast brings the coldest air of the season to many parts of the south central and southeastern U.S.</a> Winds on Saturday will be gusty behind the low, potentially topping 60 mph near the Black Hills.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-08 053809-1762605499739.png">For more information, be sure to join us on WeatherNation at :30 past the hour for your Central Regional Forecast.

Secondary severe weather season is underway across the U.S. - so called because it typically pales in comparison to the primary severe weather season in the spring. However, the fall can provide high-end severe weather threats of its own, including the December 2021 tornado outbreak. Thankfully, the severe weather setup for now through Sunday doesn't look to be on the high-end, but a few scattered severe storms will be possible.<hr><h1>Severe Storm Outlooks/Hazards</h1>Early morning severe storms will be possible along the cold front driving south. Large hail and damaging winds will be possible with any severe storms and the severe risk should diminish by sunrise.<img src="https://media.weathernationtv.com/app/uploads/2025/11/PIC 2-1762564233131.jpg">The threat for isolated severe storms will continue Saturday into Sunday as the cold front is dragged through the south. Check back in with us online or on air for an updated forecast.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-07 044714-1762516046220.png">Overnight storms are possible, but the severe threat goes down Saturday before it returns to the Southeast on Sunday. Areas along the Atlantic Coast should be weather aware for Sunday.<video src="https://media.weathernationtv.com/app/uploads/2025/11/FORECAST-1762564282904.mp4" controls="true" width="100%"></video><h2></h2>

The St. Joseph River in northern Indiana has reached unprecedented levels near South Bend, Indiana. Mayor Pete Buttigieg and the City of South Bend formally declared an emergency Wednesday.

https://twitter.com/PeteButtigieg/status/966465080421421061

South Bend was forced to close its wastewater treatment plant after it was swamped by flood waters. Untreated sewage water backed up into the river before the facility reopened at limited capacity Thursday morning. The <a href="http://www.redcross.org/get-help/disaster-relief-and-recovery-services/find-an-open-shelter">Red Cross has opened 8 shelters</a> in northern Indiana for those forced from their homes. WeatherNation spoke with Mayor Buttgieg about the dangerous situation threatening his city.

Our affiliate WJRT has been following similar flooding in Michigan that has taken the life of a one year old girl. Police say she was found in standing water in her backyard. WJRT is reporting that heavy rains and wintry weather have contributed to at least six other deaths in Illinois, Kansas and Nebraska since Monday.

https://twitter.com/WeatherNation/status/966761900590559232

Upstream on the St. Joseph River in southwest Michigan, the Coast Guard was called in to help evacuate residents. At least 40 people and their pets had to be rescued.

The Mayor of Lansing, Michigan also declared an emergency for his city. At least six neighborhoods were put under voluntary evacuations.
