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/2025/12/2025-12-10 04-09-43-1765365026277.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 040819-1765364957332.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 040836-1765364970085.png">Winds will be a problem for visibility late Wednesday into Thursday as the front moves through. Widespread 30-40 mph gusts are expected.<video src="https://media.weathernationtv.com/app/uploads/2025/12/2025-12-10 04-10-43-1765365069697.mp4" controls="true" width="100%"></video>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.

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 - Now through Wednesday, 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.Since the beginning of the week, the states of Washington and Oregon have received over a foot of rainfall. In the last 24 hours, several areas across the Pacific Northwest have seen over 5 inches of rainfall.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 044658-1765367266816.png">A deep supply of tropical moisture has arrived 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 through Friday.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Web3-1765366662594.png">Rainfall totals through Saturday morning are expected to reach over 6" for large areas along and west of the Cascades. With heavy rainfall rates, we could see flash flooding develop in addition to river flooding. 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><img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-10 045222-1765367553882.png"><img src="https://media.weathernationtv.com/app/uploads/2025/12/Web8-1765366951944.png">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/2025/12/2025-12-10 04-39-03-1765366770786.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/web9-1765366912371.png">For more details, be sure to join us live!

NORTHERN PLAINS - Today, an Alberta Clipper dove into the north-central U.S., bringing in some light snow for the northern Plains through the Great Lakes. Snowfall totals look to be fairly minimal with this first clipper, but a second will move through right behind it. Winter alerts have been issued for the northern Plains through Wednesday for heavy snow, patchy blowing snow, and potentially some freezing rain! <img src="https://media.weathernationtv.com/app/uploads/2025/12/Web1-1765367556269.png">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 system has started in the northern plains and will move through the Great Lakes into the northeast on Wednesday.<video src="https://media.weathernationtv.com/app/uploads/2025/12/2025-12-10 04-54-04-1765367667459.mp4" controls="true" width="100%"></video>The highest snow totals through Saturday morning will be across Wisconsin and Michigan.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Web1-1765367755479.png">These clippers will also bring some gusty winds to the forecast for the midwest, with some areas potentially seeing gusts up to 60 mph! However, by Thursday most of these winds should be out of the picture. Wind alerts will remain for today as a result.<video src="https://media.weathernationtv.com/app/uploads/2025/12/2025-12-10 04-58-09-1765367904013.mp4" controls="true" width="100%"></video><img src="https://media.weathernationtv.com/app/uploads/2025/12/Web1-1765367975808.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.

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.

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

MONTANA - A clipper system has been moving through the Rockies and High Plains and brought upwards of 4-7" of snowfall across portions of Montana. More snow is in store across the Northern Plains to Midwest to Northeast as the clippers move through.<video src="https://media.weathernationtv.com/app/uploads/2025/12/New Baron Video 3-1764813457932.mp4" controls="true" width="100%"></video>These totals will pile up across the northern plains, with the highest totals staying out west across the Northern Rockies.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-03 162020-1764804026521.png">Gusty winds will also play a role in the forecast. We can expect rounds of 25-30mph wind gusts. In some cases, maybe even higher than that! Watch out for those wind chill temperatures as they will drop as the winds come through with each clipper system.<video src="https://media.weathernationtv.com/app/uploads/2025/12/12-03 rnc bams3k wind-1764786148016.mp4" controls="true" width="100%"></video>Clipper systems are notorious for bringing quick-accumulating snowfall. But, even if snow totals are not significant, it doesn't mean dangerous road conditions won't be present. The Iowa Department of Transportation reports over 70% of weather-related crashes happen when there is 2" or LESS of snowfall. Use caution on snowy roadways and most importantly: SLOW DOWN.<img src="https://media.weathernationtv.com/app/uploads/2025/12/Screenshot 2025-12-02 154321-1764715481857.png">Make sure to stay tuned to WeatherNation for all the latest details on these systems!

NOAA’s supercomputer Dogwood, located in Manassas, Virginia (2023). (Image credit: NOAA)We had the opportunity to sit down with the Director of the National Weather Service, Ken Graham to discuss the supercomputer capabilities and how it will improve forecast accuracy and decision making for the nation. <video src="https://media.weathernationtv.com/app/uploads/2023/08/Ken Graham - Super Computers-1692126354220.mp4" controls="true" width="100%"></video>The National Oceanic and Atmospheric Administration (NOAA) announced the expansion of the weather "supercomputer" this week - increasing the capacity by 20%. According to NOAA, "the increased computing power and storage will help improve forecast model guidance for years to come and allow for other weather prediction advances."The Weather and Climate Operational Super Computing System (WCOSS) is actually two systems, the Dogwood and Cactus, located in Manassas, VA and Phoenix, AZ, respectively. The two computers are contracted with General Dynamics Information Technology (GDIT) as part of a acquisition, upgrade, products and services contract spanning 8 years with a 2 year option renewal.&nbsp;&nbsp;NOAA scientists expect the increase in computing power to help with more complex forecast models; the upgrade allows for 29 quadrillion calculations ... per second. This allows more data to be imputed into the computers and more data to be stored.It is part of a plan to upgrade the U.S. "GFS" or Global Forecast System Model and make the model hirer resolution. Currently, it has a 13km resolution, the goal is to get it to 9km. Additional advancements are expected with the "radiatively active aerosols" product to better predict wildfire smoke, dust and fog.The HRRR, or Rapid Refresh Model will also get a boost, with more forecast potentials and data included in each run of the model.Over 20 models run on the WCOSS. There are additional supercomputers in West Virginia, Tennessee, Mississippi and Colorado that add to NOAA's fleet. According to the National Weather Service Director, Ken Graham, “This increased supercomputing power allows for upgrades to specific modeling systems that will help weather forecasters deliver more accurate weather forecasts, watches and warnings and improved certainty in a forecast.”The latest upgrade to the WCOSS comes as NOAA advances the <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/nhc-using-a-new-hurricane-model-for-the-2023-season">Hurricane Analysis and Forecast System</a> model with the NHC.
