What are Forecast Ensembles ? Multiple forecasts from running the same weather model with slightly different inputs.

How to read Long Range Ensemble Forecasts

What to look for?

Temperatures trending downward at the same time as precipitation spikes upward... means snow!

Lines close together indicate a high confidence, while wider spreads signal uncertainty.
