Bitter cold temperatures are forecast across the northern Plains to the Mid-South through the weekend. Well below normal temps combined with gusty winds will create dangerous wind chills.

Additional atmospheric rivers are expected to impact the West later this month. Given the significant river flooding already impacting Washington and Oregon, a continued risk of flooding and landslides is expected across the region through at least late December.
NOAA National Weather Service forecast updated December 11, 2025, details "Atmospheric Rivers affecting the Pacific Northwest and California into late December," specifically December 19-25, 2025. The text warns of heavy rain, high-elevation snow, high winds, and persistent flooding risks. Map (a) shows high and moderate risks for heavy precipitation and snow across the region. Map (b), the "8-14 Day Precipitation Outlook," indicates a high probability of above-normal precipitation for most of the western U.S.

The National Water Center has issued an updated Key Messages for the ongoing Catastrophic flooding impacts this week in Washington. More info: water.noaa.gov #flooding #wawx
Key Messages for Washington Flooding Catastrophic and life threatening flooding to continue through Friday Catastrophic Flooding Impacts, Especially Along the Skagit and Snohomish Rivers, to Continue through Friday Major and/or record river flooding is ongoing, which will bring a significant risk to life and property. Overtopping of levees is likely. Considerable Flooding Impacts Across the Western Cascade Foothills to the Puget Sound to Continue through Friday Considerable small stream and moderate-to-major river flooding is ongoing. Widespread Urban and River Flooding Urban and minor-to-moderate river flooding is possible through early Friday throughout the remainder of western Washington. Potential For Landslides Landslides remain possible in areas of steep terrain within the considerable and catastrophic regions. For the latest rainfall forecasts, visit www.wpc.ncep.noaa.gov

If you live in the West, you’re likely to see the words “atmospheric river” pop up in the forecast over the next several days.

This is not a new term; in fact it was coined in 1994!

But what is an atmospheric river, and what weather hazards can you expect? Meteorologist Haley Thiem explains.

💨❄️High winds, accumulating snow, and icy conditions are expected across a number of states from Montana to Michigan today through Wednesday (Dec. 8 -10) due to two different Alberta Clipper systems moving across the northern U.S.

🚙Get the latest: weather.gov
NOAA infographic titled "Winter's Fury: Alberta Clippers." A map of the United States displays a dashed line with arrows labeled "Common low pressure track" moving southeast from the Canadian border near Montana, across the Great Lakes, to the Mid-Atlantic coast. A yellow shaded band runs along the top of this path with a label stating, "Snow will fall near and north of the low pressure track." A large purple text box explains: "As their name suggests, these fast-moving low pressure systems get their start in Canada and zip across our northern states. They can pack a punch with a narrow band of 'dry' but significant snow. In the winter, these systems commonly bring in below zero temperatures and are often responsible for white-out conditions from Montana to the Dakotas." An additional note adds, "A frigid Canadian air mass sometimes follows on the heels of a clipper system."

From Alaska to Maine, winter weather watches, warnings, and advisories are in effect today (December 1) across over 20 states due to ongoing or expected snow/ice. Make sure you're taking time to ready yourself for winter driving!

A dark-themed infographic titled "WINTER DRIVING KNOW BEFORE YOU GO." It features an illustration of a house, a yellow car, and dashed lines connecting to three main safety tips: 1) Check road conditions (Call 511 or visit your state's DOT webpage); 2) Pack an emergency supply kit (including a mobile phone charger, first-aid, non-perishable food, blankets, and battery booster cables); and 3) Ready your vehicle (Check battery, wipers, coolant, tires, and clear windows, lights, and camera). A dark blue infographic titled "WINTER DRIVING WHILE ON THE ROAD." It illustrates three vehicles on a snowy road: a snowplow, a yellow car, and a dark vehicle. Text connected to the illustration provides three main safety tips: 1) Don't crowd the plow (The road behind a plow is safer to drive on; give it plenty of room); 2) Change the way you drive (Drive slower, leave more room, DO NOT use cruise control, or brake/turn sharply); and 3) Stay alert (Keep your gas tank over half full, monitor rapidly changing road conditions, and take breaks). A dark blue infographic titled "WINTER DRIVING FOCUS ON SAFETY." It features an illustration from a driver's perspective inside a car, showing the steering wheel and dashboard. Text connected to the illustration provides three main safety tips: 1) Prevent a bad situation from getting worse (If in an accident, pull off the road, use hazard lights/reflectors, call 911, and wait for police); 2) Avoid risky driving behavior (Avoid texting, phone calls, speeding, or drug/alcohol use, as risk is higher in winter); and 3) Wear your seatbelt (Accidents are frequent in wet/icy conditions; always wear a seatbelt and ensure children are in proper seats).

Are you one of the 80+ million planning to travel for Thanksgiving this year? Whether you are driving or flying, be sure to check the weather.

While we can't control the weather, it can be a deciding factor in our travel plans (especially if you are driving). Plan accordingly and travel safe!

Following today's heavy rain in the southern plains, a slight risk for excessive rainfall will return by Sunday and push eastward early in the work week. Monitor weather.gov for the latest on what to expect for your neck of the woods.
