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!

Record Warmth Out West, Except for California's Central Valley

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!

NORTHWEST - There will be a series of strong atmospheric rivers that bring heavy rainfall, warmer temperatures, and higher elevation snow, which will be measured in feet. The next 7 days show the AR scale reaching a level 4. Flood potential is increasing, especially for river flooding, as the week rolls on.In the last 3 days, the Pacific Northwest has seen over 10" of rainfall. <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 is likely for the higher terrain of the Cascades, in addition to lower elevations. Flood Watches have been issued for Washington through Friday.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 114345-1765392231539.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 on Wednesday evening and Thursday. Another weaker system is expected on Friday.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12102-1765392328098.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 2025-12-10 114537-1765392344576.png">For more details, be sure to join us live!

NORTHEAST - The northeastern U.S. is in for some wintry weather over the course of the week, with a couple of clipper systems dropping down from the northern Plains. The clippers continue with a fast-moving clipper system that will move out of the Upper Midwest and into the interior of the Northeast on Wednesday. This system will bring a brief but disruptive round of winter weather to several states. As the system pushes east, a wide swath of Winter Weather Advisories and Warnings is issued across the Interior Northeast and the higher elevations of the Appalachians. Snowfall totals across this region&nbsp;will range from 4 to 6 inches.&nbsp;<video src="https://media.weathernationtv.com/app/uploads/2025/12/1210-1765391714895.mp4" controls="true" width="100%"></video>One of the most significant impacts will come from a corridor of Blizzard Warnings in the Central Appalachians. In this region, snow accumulations of three to six inches combined with wind gusts up to 50 miles per hour will create dangerous whiteout conditions and severely reduced visibility. Travel will be extremely difficult to nearly impossible at times, as blowing snow-coated roads and obscured sight lines will be possible.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 040825-1765364957335.png"><img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 113536-1765391741302.png">Farther north, Snowfall totals will be even heavier in the snowbelts, where lake effect snowfall is expected to pick up throughout the week. Communities across the Tug Hill Plateau and the western Adirondacks can pick up up between 8 and 16 inches of snow, continuing an active stretch of winter weather for upstate New York.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 113556-1765391765064.png">Winds will be a problem for visibility late Wednesday into Thursday as the front moves through. Widespread 30-40 mph gusts are expected.Another clipper is forecast to track quickly behind it on Thursday, threatening parts of the Northern High Plains and the Ohio Valley with a mix of heavy snow and pockets of freezing rain. In anticipation, Winter Storm Watches are already issued in eastern Montana, signaling the potential for another round of hazardous travel and wintry disruptions.&nbsp;Be cautious because the air will turn cold later this week in places that receive rain from these clippers, while the roads remain wet, black ice could be a problem at the end of the week.

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.

Hurricane Norman is continuing on its west track until Thursday night where it will start to curve northwest. Currently, sustained winds are at 85 mph, and Norman will stay a category 1 hurricane until about Thursday night. Although Norman is not looking to make direct impact with the Hawaiian islands, it could still bring some rain and rough seas to Hawaii.
