Up to 1 of the scored days in this table carry a QC flag on the observation (a CLI value that disagreed with the hourly observations, or a fallback source). They are kept in the scores and counted here rather than dropped — see methodology.
+ model too warm · − model too cold · bias interval includes zero · ★ lowest MAE · = not distinguishable from the leader · ▼ significantly worse · n < 30 greyed and unranked · CI is a 95 % moving-block bootstrap interval.

Month by month
MAE °F at lead day 1, 00Z, bilinear, daily maximum — the seasonal slice behind the window averages. A model that is excellent in one season and poor in another shows up here and nowhere else.
