U.S. Weather Outlook: Wintry Mix in the Northeast as Pacific System Delivers Rain and Mountain Snow to California
The United States will face two major weather systems, each producing distinct regional hazards. According to the National Weather Service, a clipper system tracking along the U.S.-Canadian border will bring snowfall and mixed precipitation to the Northeast, while a modest atmospheric river will return rain, high‑elevation snow, and gusty winds to California and the Intermountain West .
Northeast: Snow and a Wintry Mix from a Fast‑Moving Clipper
A compact Alberta clipper will sweep across the region, spreading light to moderate snow across northern New England and the eastern Great Lakes. Farther south, warmer surface temperatures will support a wintry mix of snow, sleet, and freezing rain.
Primary Impacts: Slippery roads, reduced visibility, pockets of light icing
Temperature Range: 20s to low 30s
Timing: Morning through early evening
While accumulations are expected to remain modest, the combination of mixed precipitation and sub‑freezing surfaces may create hazardous travel conditions during peak commute hours.
Mid‑Atlantic & Southeast: Mild to Warm, Mostly Dry
The Mid‑Atlantic will remain south of the clipper's influence, with dry conditions and seasonable temperatures.
Across the Southeast, warm and humid air persists, with highs in the 70s and 80s and isolated showers possible along the Gulf Coast and Florida Peninsula.
Mid‑Atlantic Highs: 40s-50s
Southeast Highs: 70s-80s, near 90 F in parts of Florida
Hazards: Isolated thunderstorms in Florida
Midwest & Great Lakes: Cold Behind the Clipper
As the clipper exits, colder air settles across the Upper Midwest and Great Lakes. Expect partly cloudy skies with lingering lake‑effect flurries.
Highs: Teens to 30s
Hazards: Wind chills in northern areas
Central & Southern Plains: Quiet and Seasonal
The Plains will experience calm, stable weather with sunshine and seasonable temperatures.
Highs: 30s-50s
Hazards: None significant
California & Intermountain West: Atmospheric River Brings Rain, Snow, and Wind
A Pacific system tied to a modest atmospheric river will bring widespread precipitation to California. The NWS reports lower‑elevation and coastal rain, high‑elevation snow or wintry mix, and gusty winds, with moisture spreading into the Intermountain West .
California Coast: Steady rain, breezy conditions
Sierra Nevada: Heavy snow at higher elevations; wintry mix at mid‑levels
Intermountain West: Rain and snow showers expanding eastward
Hazards: Mountain travel disruptions, strong gusts, localized flooding
This system will be the primary national weather driver in the western U.S., with snow levels fluctuating as warmer Pacific air interacts with colder interior air.
Southwest: Mild and Mostly Dry
Arizona, New Mexico, and southern Nevada will see calmer conditions, with mild temperatures and limited precipitation outside of higher terrain.
Highs: 50s-70s
Hazards: None widespread
Pacific Northwest: Clouds and Light Precipitation
The northern tier of the West Coast will see cloud cover and occasional showers as moisture spreads inland.
Highs: 40s-50s
Hazards: Light coastal rain
Alaska & Hawaii
Alaska: Cold with scattered snow showers
Hawaii: Warm, humid, and breezy with passing showers
National Summary
Tomorrow's weather pattern highlights a classic winter contrast:
A wintry mix in the Northeast, driven by a fast‑moving clipper system
Warmth across the South, with isolated thunderstorms in Florida
A moisture‑rich Pacific system bringing rain, mountain snow, and gusty winds to California and the Intermountain West
