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.

<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 the cold front moves inland tonight, storms will become more widespread, especially through Oregon and northern California. Dropping overnight temperatures will ensure snowfall in the mountainous regions, which will carry into Thursday. As the front pushes south, Southern California will see a good chance of 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 also.<video src="https://media.weathernationtv.com/app/uploads/2025/11/FORECAST-1763071752458.mp4" controls="true" width="100%"></video><h1>CALIFORNIA IMPACTS</h1>Winter alerts have already been issued for the Sierra Nevada, beginning tonight 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" is possible above 5000 feet.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Web3-1763031752667.png"><img src="https://media.weathernationtv.com/app/uploads/2025/11/Web1-1763031782461.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 70 mph along ridge tops. With snow falling, whiteout conditions will make driving impossible.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Web2-1763031823486.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.Flood Watches have been issued for portions of the San Joaquin Valley and into the foothills of the Sierra Nevada, as well as northern California, through the end of the week. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Web2-1763031895788.png"><h1><img src="https://media.weathernationtv.com/app/uploads/2025/11/Screenshot 2025-11-12 160928-1762989012110.png">NORTHWEST IMPACTS</h1><img src="https://media.weathernationtv.com/app/uploads/2025/11/Web1-1763031948354.png">No winter alerts have been issued for the Cascades yet, but they will likely be needed as totals reach the foot range in some select spots.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Web1-1763032086690.png">

Weekend System Brings Snow & Ice In Northeast

A ridge of high pressure that brought record warmth to the West is sliding eastward. This means the heat will shift east as well, and we could see multiple records broken from Thursday through Sunday! The temperatures will climb this week as the ridge dominates!<video src="https://media.weathernationtv.com/app/uploads/2025/11/2025-11-13 03-32-43-1763029980858.mp4" controls="true" width="100%"></video>On Friday, multiple cities will make a run for the records, including Oklahoma City and Tulsa.<img src="https://media.weathernationtv.com/app/uploads/2025/11/Web1-1763030014931.png"><h1>Plains &amp; Midwest</h1>Temperatures will run 10°- 20°+ above average for a lot of folks. Kansas City normally averages 55° for this time of year, and will see highs in the low 70s on Friday and Saturday.

With photos and videos prove that skygaziers are spotting them much farther south in the United States and Europe over the last two years. It begs the question...Why are we seeing these geomagnetic storms that are far more reaching than normal?The reason? The sun is undergoing a dramatic magnetic shift. Every 11 years, its poles reverse, creating intense magnetic twists and disturbances that fuel these vivid light shows.Aurora lovers, rejoice! The Space Weather Prediction Center correctly said Tuesday, November 11th, that aurora chances could be seen as far south as Alabama and California. Space weather forecasters predict more dazzling displays AGAIN Wednesday night into Thursday.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1988725181372629334" src="https://x.com/NWSSWPC/status/1988725181372629334"></div>ANOTHER coronal mass ejection (CME) is expected to arrive at and impact the Earth with the potential for elevated geomagnetic response, AKA: more auroras.

Solar Storm Visible as far south as The South - Another Round Arrives Tonight

The season’s first Arctic blast 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. Multiple record lows were set over the past few days across the south and southeast. The good news: we're warming back up!<img src="https://media.weathernationtv.com/app/uploads/2025/11/Web 1-1762947369987.png">We will see a pattern change this week, with temperatures becoming average, and then above average as a high-pressure system ridges back in by the end of the week!<video src="https://media.weathernationtv.com/app/uploads/2025/11/2025-11-12 06-35-47-1762947394918.mp4" controls="true" width="100%"></video><img src="https://media.weathernationtv.com/app/uploads/2025/11/Web 2-1762947531574.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. 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.
