United States January 2026 Monthly Weather Forecast: NOAA Detailed Outlook

Hey buddy! January 2026 looks like a classic weak La Niña-influenced month according to the latest NOAA Climate Prediction Center (CPC) and ECMWF data. Overall, above-normal temperatures dominate the southern and eastern U.S., while the north (especially Northwest and Northern Rockies) has chances for below-normal temps and wetter/stormier conditions. Precipitation is likely above normal in the north, drier in the south. Snow potential is good for northern ski areas, but milder in the south. Forecasts are probabilistic – check local updates!

General Outlook Summary (January 2026)

• Temperature: Above normal across the South, Southeast, East Coast, Southwest, and California. Below normal chances in the Northern Rockies, Upper Mississippi Valley, Pacific Northwest, and Alaska (especially Southeast).
• Precipitation: Above normal in the Pacific Northwest, Northern Rockies, Great Lakes, and parts of the northern Plains. Below normal (drier) in the Southwest, southern Texas, Gulf Coast, and Southeast.
• Influences: Weak La Niña persists (transition to neutral likely by spring). This favors a north-south split: stormier north, warmer/drier south.
• Snowfall: Better chances in northern/northwestern regions for ski season; lower in southern mountains.
