Strong upper-level ridging off the coast of California is currently dominating the weather pattern, bringing widespread sunshine but also a lack of precipitation. The one exception is in the state's Central Valley, where locked-in fog has kept temperatures chilly and skies gray. More on that in a minute...<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 131930-1765398197848.png">High pressure in the upper levels of the atmosphere means sinking, compressing air, and generally warmer temperatures. On Tuesday, multiple record high temperatures were set, including 84° in Anaheim! <img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 132558-1765398582761.png"><img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 132733-1765398466041.png">High temperature records up and down the western third of the country could fall through the weekend, as the upper-level ridge is forecasted to stubbornly remain in place over the coming days! <h1>Tule Fog</h1>You may have noticed the persistent fog in the Central Valley, or even the much colder temperatures compared to the rest of the state. This fog is known as Tule (TOO-lee) Fog, and is somewhat common in the winter months. It's a radiational fog that occurs overnight, gets locked into the Central Valley (sometimes the Bay Area), and is beneficial to California's agricultural industry. However, with high pressure in the upper levels of the atmosphere not going anywhere lately, the Tule Fog has been incredibly persistent. <img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 134007-1765399214088.png">The fog is making a huge difference in temperatures! Early Wednesday afternoon, Bakersfield was sitting under gray skies and a temperature of 42°. At the same time, over the Grapevine and into the valleys, temperatures were pushing into the upper 80s with blue skies!

The Northern Tier of the country is no stranger to cold, and Tuesday morning proved that with multiple record lows. Watertown, New York, saw a morning low of -18°. This beat out the old record of -16° in 2008. Temperatures on Wednesday have been quite mild and will be for most of Thursday before cooling behind a clipper system Thursday night.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12-10 rnc bams3k overnight-1765417374022.mp4" controls="true" width="100%"></video><h1>Another Blast Of Cold Air</h1>Temperatures rebound for a day or two, with more dangerously cold weather expected at the end of the week and into the weekend. Temperatures will be 30° BELOW average for some, as this arctic air invades the Northern Plain and Northeast.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 041854-1765365546543.png">Low temperatures Friday through Sunday will drop below zero for many.

NORTHWEST - An atmospheric river aimed at the northwest has been responsible for rainfall totals of over a foot across the northwest. Even as rain starts to slow down into early Thursday, the rivers will still remain high through the end of the week.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 114305-1765392214647.png">With this event being so warm, significant flooding remains likely for the higher terrain of the Cascades, in addition to lower elevations. Flood Watches remain in place for Washington, Idaho, and Montana through Friday.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 150403-1765404249718.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. Landslides will remain a risk, as a few have already occurred across the northwest.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1998497888079368241" src="https://x.com/WeatherNation/status/1998497888079368241"></div>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 through Thursday. Another weaker system is expected on Friday.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12-10_rnw_bams3k overnight-1765417272963.mp4" controls="true" width="100%"></video><h3>River Flooding</h3>Once the rain slows down, rivers will still be running high. The Skagit River near Mount Vernon is forecast to reach major flood stage into early Thursday morning.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 174305-1765413802847.png">Many of the rivers in the northwest are expected to reach moderate to major flood stage through the end of the week (top of page). Here's a visual of the Puyallup River in Washington earlier on Wednesday.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1998814974957765052" src="https://x.com/WeatherNation/status/1998814974957765052"></div><h3>Snow Forecast</h3>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 2025-12-10 183933-1765417293045.png">For more details, be sure to join us live!

Our next clipper system is set to move through the High Plains on Thursday. With temperatures taking a bit of a break from intense cold, this system will move through some warmer air, and that may lead to a rain/snow mix and potentially some freezing rain. The National Weather Service has issued winter alerts from Montana through Minnesota, with a few counties under winter storm warnings and one in South Dakota under an ice storm warning.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 183527-1765416978621.png">As is typical with clipper systems, snowfall totals are often smaller, but sometimes the smaller totals lead to worse roads. In fact, 75% of accidents happen when there is less than 2" of snowfall, according to the Iowa Department of Transportation. Here's a look at our forecasted totals with snow and ice from the High Plains through the Midwest.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 183632-1765417011977.png">Forecast models suggest about one-tenth of an inch of ice across portions of northwest Iowa, southwest Minnesota, North Dakota and South Dakota through Thursday.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 183641-1765417019653.png">The clipper system drops in on Thursday morning, bringing snow for northern North Dakota and Minnesota, and potential ice into southern North Dakota and South Dakota. This system moves through quickly and heads towards the Midwest, but lingering moisture and snowfall continue behind this as cool air falls in behind the front. This will continue through the end of the week and into the early weekend.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12-10_rnc bams overnight-1765417102628.mp4" controls="true" width="100%"></video>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.

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!
