Arctic air is set to take a deep dive into the Southern United States. Millions of Americans will be impacted by these cooler temperatures into the work 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 2025-11-09 175430-1762736076646.png">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 2025-11-09 175507-1762736113770.png">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 2025-11-09 175448-1762736121311.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 2025-11-09 175552-1762736159292.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.

The lake effect snow season has arrived, with heavy snow expected now through Tuesday. Early Sunday, the snow was just starting to stack up. <img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-09 174930-1762735776070.png"> Winter weather alerts have been issued all across the shores of the Great Lakes through Tuesday. Snow in these areas could top 8-12" in some locations, with heavy snowfall rates likely reducing visibility at times, making travel very difficult.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-09 175012-1762735953310.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. 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>As the winds shift slightly from the NNE 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/2025/11/11-09_rne-1762736027472.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/Web 6-1762700060900.png">Brutal Wind Chill values will accompany the snow.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Web 7-1762700204281.png">You can catch the latest forecast for the Great Lakes anytime by using the WeatherNation app to view the Central Regional Forecast.

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 continue to build in. That will keep the quiet weather around, but will start to push temperatures into historic levels over the coming days.<img src="https://media.weathernationtv.com/app/uploads/2025/11/MON AND TUE-1762736389899.png">We've been struggling to find many who will complain openly about the 70s and 80s around the Intermountain West, or even the low 90s around Phoenix. It's in southern California, where people might have a different reaction to 90 in the forecast, because they know what that could mean: wildfire danger.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-09 080534-1762700911315.png"><img src="https://media.weathernationtv.com/app/uploads/2025/11/HEATY HEA-1762736244587.png">Any time high pressure sets up somewhere in the Great Basin or Four Corners, there could be offshore flow, winds blowing from the desert to the Pacific Ocean. When that happens, those winds are much warmer and drier as they cross up and over the San Gabriels and San Bernardinos. The Storm Prediction Center is highlighting areas just north of LA with an ELEVATED risk for wildfire growth today, but it hasn't risen to the level of a Red Flag Warning.<img src="https://media.weathernationtv.com/app/uploads/2025/11/LOS ANGNG-1762736291242.png">There is some good news in all of this: it's a short-lived snap of hot weather. By Tuesday and Wednesday, the breezy winds will back off, and that should help temperatures settle closer to normal for this time of year.

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.

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.

A series of atmospheric rivers has been responsible for wet, windy, and snowy weather in the northwestern U.S over the last few weeks. Our system is currently moving through Washington, Oregon, and the northern tier of California, bringing heavy rainfall and snow. Above is the forecast rainfall totals for the next several days. Gold Beach in Oregon has already picked up 2.51" of rainfall in the past 24 hours.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Web1-1762440546220.png">With multiple inches of rain on the way, the Weather Prediction Center is monitoring coastal areas at a level 1, MARGINAL, risk for excessive rainfall that may lead to flash flooding.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-05 095854-1762361963192.png"><h2>Timing</h2>Precipitation across the Northwest should continue for the next few hours.

Phoenix, Arizona is known for its blazing 100°+ heat during the summer. But early May is a bit, well, early for the kind of heat that the Valley of the Sun saw on Sunday.

Phoenix set a record high on Sunday, with temperatures soaring into the mid-100s. Through 1pm Phoenix time on Sunday afternoon, Sky Harbor Airport had warmed to 106°, breaking the old daily record of 105° from 1947. It's also the warmest reading so far in 2018 for Arizona's capital city.

<img class="alignleft size-full wp-image-91068" src="https://media.weathernationtv.com/app/uploads/2018/05/phx-rec.jpg" alt="" width="1920" height="1080" />

Sunday's 100°+ reading marks the fourth triple-digit temperature so far in 2018 for Phoenix, a remarkable feat for a city that averages its first 100° day on May 12th.

And of course, the heat isn't going away anytime soon. The week ahead promises more near-record level high temperatures and it's probably also worth noting that Phoenix averages 110 days of 100°+ high temperatures per year. Hopefully you're near a <a href="https://www.phoenix.gov/parks/pools">Phoenix-area pool</a>!

&nbsp;

&nbsp;

A big ridge of high pressure is steering , and allowing the sun to bake Arizona and much of the Four Corners states, along with California and Nevada, with well above-average temperatures for this time of year.<img class="alignleft size-full wp-image-91069" src="https://media.weathernationtv.com/app/uploads/2018/05/west-pattern.jpg" alt="" width="1920" height="1080" />
