1997-98 DJF has the highest correlation of all analogs, by far

El NiƱo snowfall patterns 1950-2026. I anticipate a lot of ā€œwinter cancelā€ opinions after Christmas, but the party will just be getting started! History says interior Northeast first, then the coast follows late season.

Pick your CWA from the main page, click ā€œmapā€ in the top menu, then state map tab. Be sure to change what you intend to map.

Np. In recent history, CPC seasonal outlook is better than climo. 10/13 winters improved on equal chances. Note that these are November issued outlooks as I figured Iā€™d give them a fair shake instead of using October issued DJF outlooks.

The issue I have is that CPC winter outlooks are not probabilistic temperature forecasts. CPC uses tercile binsā€¦ so evaluated based on the observed terciles, you get this.

Contrary to social media dismissalĀ of the initial NOAA Winter 2026-2027 seasonal forecast, NOAA's forecasts for the last two strong El NiƱos were not too warm. The forecast should not be dismissed out of hand to confirm one's hopes or biases.
