Experimental Precipitation Forecasts

Extended Winter Season Precipitation Forecasts for CONUS

This page provides forecasts of precipitation for the extended winter season of November-March. These forecasts, and the associated historical skills, are shown using two different statistical models. The first model uses only sea surface temperatures as predictors, while the second is a weighted ensemble of four different statistical models. Learn More

We include: Historical Skill, the reforecast skill across CONUS for our statistical models versus the skill of the North American Multi-Model Ensemble (NMME) forecasts; Forecasted Probabilities, the median forecasts for each year shown spatially; Time Series, the time series of the median forecasts, at each CONUS basin, for the last 30 years along with the forecast for this winter.
