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 2025-12-11 162825-1765495734843.png">High pressure in the upper levels of the atmosphere means sinking, compressing air, and generally warmer temperatures. On Wednesday, records fell up and down in the western states. <img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-11 162926-1765495893172.png"><img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-11 162916-1765495902909.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 2025-12-11 163249-1765496047612.png">The fog is making a huge difference in temperatures! On Thursday afternoon, Bakersfield was sitting under gray skies and a temperature of 45°. 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!

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.

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 rebounded quickly Wednesday and Thursday, but another shot of arctic air is on the way.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-11 110232-1765476183612.png"><h1>Another Blast Of Cold Air</h1>More dangerously cold weather expected at the end of the week and into the weekend.

Our next clipper system is moving through the Plains into the Midwest Thursday into Friday. Another system on its heels will deliver more snow to the region this weekend. With temperatures taking a bit of a break from intense cold with the first system, it will move through some warmer air, and that is leading to some freezing rain. The National Weather Service has issued winter alerts from Montana through the Ohio River Valley, with one county in South Dakota under an ice storm warning.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-11 070841-1765462134308.png">As is typical with clipper systems, snowfall totals are often on the lower end (1-3"), 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. As snow moves east of the Mississippi, totals look to increase as more moisture is pulled into the system. Illinois to Kentucky could see totals topping 3-6".<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-11 071108-1765462282971.png">Another round of snow falls almost in the same locations Friday night through the day Saturday. As we add in this next round of snow, totals through Sunday morning could top 6-10 inches from central Illinois through northern Kentucky.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-11 071115-1765462290130.png">The first system will quickly move farther south and east on Thursday, bringing snow across the Midwest throughout the day. Snow moves into Indiana and the Ohio Valley during the evening and overnight, tapering off throughout the morning on Friday. The next round of snow develops late Friday in the Dakotas before moving across the Midwest and Ohio Valley on Saturday.<video src="https://media.weathernationtv.com/app/uploads/2025/12/2025-12-11 07-13-42-1765462473228.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.

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/2025/12/12-09_rne-1765403705611.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 145530-1765403760115.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.

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.
