2025-2026 Winter Outlook: NOAA Latest Forecast & Snow Day Implications (Updated Dec 2025)

As of December 31, 2025, NOAA’s Climate Prediction Center (CPC) confirms a weak La Niña is active and influencing the 2025-2026 winter (December-February). La Niña conditions are favored to persist through the core winter months but remain weak, with a high chance (around 60-68%) of transitioning to ENSO-neutral by January-March 2026. This weak phase means classic La Niña patterns will appear, but not as extremely as in strong events.

Typical La Niña winters bring cooler and wetter conditions to the northern US (more snow potential), while the South stays warmer and drier (fewer snow days). Here’s what it means for snow days in major regions – perfect for predicting school closures!

Temperature Outlook (DJF 2025-2026)

• Below-normal temperatures favored across: Northern Plains, Upper Mississippi Valley, western Great Lakes, Pacific Northwest, and parts of northern Rockies. → Higher chance of cold snaps → More snow days in Midwest & northern states!
• Above-normal temperatures likely in: Southeast, Gulf Coast, Southwest, southern Plains, East Coast, and California. → Warmer South = Very few snow days (maybe 1-2 rare events).
• Equal chances (EC) or mixed in central US.

Precipitation & Snow Potential Outlook

• Above-normal precipitation most likely in: Pacific Northwest, northern California, northern Rockies, northern Plains, western Great Lakes. → Lake-effect snow belts (e.g., Buffalo, Cleveland) could see heavy accumulations → High snow day odds!
• Below-normal precipitation favored in: Southwest, southern Texas, Southeast, Gulf Coast. → Drier & warmer = Almost no snow days.
• Northern tier (including Great Lakes & interior Northeast) has good potential for increased snowfall due to colder air + moisture from storms.

Regional Snow Day Expectations – 2025-2026 Season

Region / States	Temperature Trend	Precipitation Trend	Snow Day Potential (2025-2026)
Northeast (NY, PA, MA, interior)	Mixed/Equal chances	Above-normal in parts	High – 12-20+ possible, especially lake-effect & nor’easters
Midwest / Great Lakes (IL, MN, WI, MI)	Below-normal favored	Above-normal	Very High – 20-30+ days, heavy lake-effect snow expected
Northern Plains & Rockies	Below-normal	Above-normal	High – Frequent cold & snow events
South (GA, TX, NC, FL)	Above-normal	Below-normal	Low – 1-4 rare icy/snow events max
Pacific Northwest	Below-normal in parts	Above-normal	High – Wet & cool = More mountain & lowland snow

Key Takeaway for Snow Days: If you live in the northern tier (Midwest, Great Lakes, northern Northeast), prepare for an active winter with more school closure chances than average! Southern states will likely see business-as-usual with rare disruptions. Our calculator uses these patterns + real-time data for your ZIP-specific prediction.

Factors considered:

1. Snowfall depth (in inches or centimeters)
2. Wind chill and visibility
3. Road condition reports
4. Storm timing (daytime vs. overnight)
5. Temperature drop rates
6. Regional patterns and history of closures

By merging all this data, the Snow Day Predictor provides an accurate, easy-to-read estimate that helps you plan ahead.
