NORTHWEST - Monday through Wednesday, we will see a series of strong atmospheric rivers bring very heavy rainfall, warmer temperatures, and high elevation snow that will be measured in feet. Flood potential is increasing, especially for river flooding, as the week rolls on.<h1>Mon - Wed</h1>A deep supply of tropical moisture arrives Monday from the "pineapple express," or atmospheric river. Intense rainfall, gusty winds, and heavy mountain snow are expected. The ridge of high pressure helping to steer the tropical moisture northward will also lead to above-average temperatures, bringing snow levels up in elevation for Washington, Oregon, and Idaho.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-06 055639-1765026414726.png">With this event being so warm, significant flooding is likely for the higher terrain of the Cascades, in addition to lower elevations! Flood Watches have been issued for Washington until next Friday. <img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-07 174320-1765154679574.png">Rainfall totals through Thursday are expected to top 7-12 inches for large areas along and west of the Cascades. With heavy rainfall rates, we could see flash flooding develop in addition to river flooding.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-07 174347-1765154685667.png">As all of the moisture adds up and runs off into creeks, streams, and rivers, water levels will rise dramatically through the middle of the week. Many rivers are expected to reach moderate to major flood stages, including the Snoqualmie and Snohomish.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-07 064747-1765115274969.jpg">Moisture will great increase through sunrise Monday, with intense rainfall rates. As this moisture moves east and hits colder air in the Rockies more of the rain will turn to heavy snow. Temperatures will continue to climb, leading to higher and higher snowfall levels. A break arrives toward Wednesday evening and Thursday. Another weaker system is expected on Friday.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12-07_rnw cat precip-1765154725778.mp4" controls="true" width="100%"></video>Snow will be very heavy east of the Cascades, especially above 6,000 feet. Snow levels will go up and down quite a bit through the event, so driving over mountain passes in the afternoons may yield only rain at times, while at other times intense snow is expected. The Cascades in Oregon are expected to see snow only at the highest elevations.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-07 174512-1765154717493.png">For more details, be sure to join us at :50 past the hour!

Alana Cameron was born and raised in Canada in the city of Mississauga, just outside of Toronto. Alana is the oldest of 4 siblings, all close in age, and grew up playing outside with them in all types of weather. After graduating high school, Alana moved to study at the University of British Columbia in Kelowna for a year before transferring to Dalhousie University in Halifax, Nova Scotia where she completed a Bachelor of Science in Physics and Atmospheric Science. Upon completion, Alana moved back to Toronto where she completed a post-grad degree in Meteorology at York University. After her post-grad, she went on to complete another post-grad in Broadcast Journalism - TV News at Fanshawe College in London, Ontario. During her final year of studies she had the privilege of interning with the best in the business in Canada at The Weather Network. Once she finished her internship, she got the call from small-town Denison, Texas where she accepted a job as an on-air meteorologist at KTEN-TV, right in tornado alley, covering severe weather from Sherman/Denison (North Texas) to Ada (Southern Oklahoma). After the most active tornado season Oklahoma had seen in May 2019 (105 tornadoes!) Alana is excited to join WeatherNation to cover weather all across the nation.

NORTHERN PLAINS - Starting Monday, an Alberta Clipper will dive into the north-central U.S. to bring in some light snow for the northern Plains through the Great Lakes. Snowfall totals look to be fairly minimal with this first clipper.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12-07_rnc bams overnight for monday-1765157490425.mp4" controls="true" width="100%"></video>The next system moves in fairly quickly behind. Wnter Storm Watches have been issued for the northern Plains on Tuesday for heavy snow, patchy blowing snow, and potentially some freezing rain on Tuesday morning.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-07 183329-1765157711151.png">This next clipper starts to push into the Northern Plains on Tuesday morning. Since we've seen winds return from the south, temperatures will be warmer with this next clipper which means rain, freezing rain, ice, and snow will be a problem. This starts with the northern Plains through the Great Lakes late Tuesday and into the northeast on Wednesday.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12-07_rnc to rne tuesday to wednesday-1765157790975.mp4" controls="true" width="100%"></video>The worst of the ice appears in North Dakota, Minnesota, and Wisconsin. Snow looks to get heavier into the Appalachians out east by late Tuesday and into Wednesday.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-07 183832-1765157919306.png">For more information on this, be sure to join us on WeatherNation at :10 past the hour for your east regional and :30 past the hour for your central regional.

A Few Clippers In the Forecast

The Northern Tier of the country is no stranger to cold. High and low temperatures will be well below average. As some of the air starts to slide east, areas like New England will take the brunt of the Polar plunge. <img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-07 174638-1765154804388.png">Along with the continued pushes of colder air, the strong northerly winds will create wind chill factors well below zero! When it gets this dangerously cold, even if it only lasts a day or two, bring the pets inside and remember to check on neighbors who might be susceptible to this. If you have to venture out, it's important to cover any exposed skin, as frostbite can set in after as little as 30 minutes.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-01 093932-1764607220609.png"><h1>But wait, there's more</h1>It's like clockwork at this point. Temperatures rebound for a few days and back down they go closer to the weekend. More dangerously cold weather slides in Thursday and Friday.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-07 073203-1765117998448.jpg">Stay tuned to WeatherNation for the latest details.

DENVER, CO - Denver saw its first significant snow this season earlier this week, with 6.5 inches reported downtown! The highest totals were reported in the higher elevations, with 11 inches recorded in Genesee.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-04 095720-1764867453909.png"><h1>Forecast Snow</h1>Further snow is in store for the Rocky Mountains as a frontal system dives in. Precipitation began in northern Utah Friday evening and will spread across Colorado overnight and into Saturday morning. Another round of snow is likely for the weekend with higher moisture content coming from the Northwest.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-05 202547-1764991557250.png"><video src="https://media.weathernationtv.com/app/uploads/2025/12/rockieswnoww-1764991689293.mp4" controls="true" width="100%"></video>With today's round and our late-week round, snowfall totals may reach upwards of a foot plus in the higher elevations.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-05 202838-1764991729249.png">This snowfall is more than welcome for some of the ski resorts in the Rockies. With not that many runs open, 12-15" in places like Steamboat Springs will make a difference.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-05 202904-1764991750430.png">Make sure to stay tuned to WeatherNation for the latest on snowfall totals across the front-range.

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.

Multiple low-pressure systems moving across the country will bring heavy rain to the Gulf Coast through the end of the week, but on the northern periphery of these lows, cold air will linger, turning rain into snow and ice! The snow started falling Thursday morning in Texas and Oklahoma before moving east Thursday afternoon. <div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1996640648766628256" src="https://x.com/WeatherNation/status/1996640648766628256"></div> Winter weather advisories are in effect through Friday afternoon from North Carolina through eastern Maryland for light/moderate snow and some light icing. Expect roads to be slick with temperatures in the 20s.<img src="https://media.weathernationtv.com/app/uploads/2025/12/pic6-1764963628163.png">Virginia into North Carolina and some areas around the Chesapeake Bay will see a round of mostly snow on Friday morning, with moderate ice accretions possible along the Blue Ridge Escarpment in Western North Carolina. Some snow may linger along the Mid-Atlantic coast into New Jersey and Delaware into the afternoon and early evening.<video src="https://media.weathernationtv.com/app/uploads/2025/12/FORECAST-1764971120854.mp4" controls="true" width="100%"></video>Snow accumulations look mostly minor, generally 1-3 inches, but higher elevations in the Blue Ridge Mountains could see some 3-6 inch totals. Freezing rain and sleet aren't expected to cause major issues, but elevated surfaces (like bridges and overpasses) could be slick, primarily in North Carolina Friday morning.<img src="https://media.weathernationtv.com/app/uploads/2025/12/1-1764905174956.png">T
