The season’s first Arctic blast has surged into the South, arriving nearly three weeks ahead of meteorological winter, which begins December 1. Driven by a deep upper-level trough, this system has funneled frigid Canadian air all the way down to Texas. As a result, temperatures across much of the region are running 15 to 25 degrees below average.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 072556-1762871169290.jpg">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;Low temperatures this morning got down to the 20s in northern Florida.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 105030-1762883438814.png">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 2025-11-10 172620-1762820787420.png">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.

Karissa is the Director of On-Air Operations at WeatherNation. Karissa grew up loving math and science, but really fell in love with Meteorology while attending the College of DuPage in Glen Ellyn, Illinois. After two summers of storm chasing in the central plains, she knew that it was the career path for her. Standing in front of a thunderstorm and feeling the cool outflow knock her over was an experience she will never forget. After two years at COD, she transferred to Metropolitan State University of Denver. Karissa graduated Magna Cum Laude with a Bachelors of Science in Meteorology. Her high school and college speech and meteorology professors were extremely supportive and pushed her to succeed. Before joining the WeatherNation team, she previously worked as the Morning Meteorologist at KCAU-TV in Sioux City, Iowa and at WMBD-TV in Peoria, IL. She recently was part of a National Edward R. Murrow award winning team for breaking news for their coverage of the EF-4 tornado in Washington, Illinois. In her free time, Karissa enjoys cooking and trying new foods. She is a self proclaimed 'TV Junkie' who can get into just about any show. She is a die hard Chicago sports fan who loves attending professional sporting events.

Winter alerts have already been issued for the Sierra Nevada as a large digging trough disrupts the <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/warm-weather-sticks-around-the-west">warm ridge that's been residing in the west</a>. The west can expect widespread rain chances, mountain snow and cooler temperatures for the rest of the work week.<h1>SET-UP</h1>A digging mid to upper level trough will bring in widespread vertical lift to the western U.S. As the trough helps draw in tropical moisture, it will meet a cool low pressure system at the surface. As a cold front crashes east and south, precipitation chances will spread from border to border, into the Cascades, Rockies, and eventually across the country.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 073335-1762871622394.png">Onshore flow will begin Wednesday allowing for a few pre-frontal showers. As the cold front moves inland Wednesday night, storms will become more wide spread, especially through Oregon and northern California. Dropping overnight temperatures will ensure snowfall in the mountainous regions, that will carry into Thursday. As the front pushes south, southern California will see a good chance at rain by Thursday evening. We may even see some snow at the highest elevation peaks in SoCal. As the surface low wraps up within itself, scattered showers and mountain snow will continue across the Pacific northwest Thursday.The first wave will move into the Rockies and Four Corners states on Friday, as another trough comes ashore. This will mean another round of precipitation from Northern California to the Canadian border, moving into the northern Rockies for the weekend. <video src="https://media.weathernationtv.com/app/uploads/2025/11/Wide west Bams-1762872266764.mp4" controls="true" width="100%"></video><h1>CALIFORNIA IMPACTS</h1>Winter alerts have already been issued for the Sierra Nevada, beginning Wednesday evening and lasting through the end of the day on Thursday. One to two feet of snow is expected at and above pass level, and 4-12" possible above 5000 feet. <img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 072919-1762871768828.png"><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 073736-1762871871090.png"><a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weather.gov/rev">NWS Reno</a> is also highlighting the danger of the winds. Gusts will easily reach 40 mph, but could exceed 100 mph along ridge tops. With snow falling, whiteout conditions will make driving impossible. <img src="https://media.weathernationtv.com/app/uploads/2025/11/WeatherStory3-1762872780059.png">Rainfall totals will be heaviest along the northern California coastline where the brunt of the moisture is focused from the atmospheric river. We will have to watch out for totals in southern California to reach 1-2" at lower elevations and 2-4" in the mountains and hills. <h1><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 075429-1762872879293.png">NORTHWEST IMPACTS</h1>Coastal areas will see the highest rain totals, especially in southwest Oregon. <img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 075821-1762873129219.png">No winter alerts have been issued for the Cascades yet, but they will likely be needed as totals reach the 1-2 foot range. <img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 080034-1762873243169.png">

The lake effect snow season has arrived, with heavy snow expected now through Tuesday. Places in the Upper Peninsula of Michigan have already received a foot of snow! <img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-10 054716-1762778844004.jpg"> Winter weather alerts remain in place all across the shores of the Great Lakes through Tuesday. An additional 6-12" in some locations, with heavy snowfall rates likely reducing visibility at times, will make travel very difficult.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 073236-1762871565435.jpg"><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 105614-1762883788305.png"><h1>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.<h1>Forecast</h1>With winds coming over the Great Lakes, we can still anticipate lake effect snowfall to continue. Next, a quick-moving clipper will move through to bring a few wintry bands to the snowbelt.<video src="https://media.weathernationtv.com/app/uploads/2025/11/11-11 rne-1762883738383.mp4" controls="true" width="100%"></video>Take this snow event as an example for the next one, make sure your vehicle is ready for winter travel with some good tread on your tires and a winter driving kit.

If it hasn't been wet, it's been warm out West. This week looks no different as our good friend, an Upper Level Ridge, will keep hold for the next day. That will keep the quiet weather around, but will start to push temperatures into historic levels into midweek. Plenty of records fell over the weekend and on Monday, from California to Arizona.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-10 201032-1762830639778.png">Temperatures look to run above average through Wednesday for a lot of our southwestern cities.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-11 072530-1762871137794.png"><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-10 172824-1762820909165.png">There is some good news in all of this: it's a short-lived snap of hot weather.

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.

A system has been bringing snow across the Plains and Midwest on Saturday. This same system will continue to push through the Great Lakes into Sunday morning. Some areas have already seen some snow accumulation in the last 24 hours.<img src="https://media.weathernationtv.com/app/uploads/2025/11/pic6-1762642526724.png">Moderate rainfall and lighter snow will continue to drift east with the low-pressure system into Saturday night and Sunday morning. <video src="https://media.weathernationtv.com/app/uploads/2025/11/FORECAST-1762633208979.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.

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>
