Instantaneous temperature — MAE °Ft2

Scored against the observed 2 m temperature at the same instant (ASOS routine METAR). This is the headline variable: the same four instants on the forecast and the observation side. These pages are always bilinear interpolation, the headline method. The nearest-node variant, and every other window/initialization/interpolation/variable combination, is published on each permanent link below — follow any number.

Against the NWS daily extremes (secondary)

This comparison scores four 6-hourly forecast samples against the true daily extreme, so it includes a sampling penalty. The size of that penalty depends on each model's own diurnal amplitude, which is one of the things this site measures, so these numbers are published for operational relevance and are never used for ranking.

Model availability at this station

Each model is scored only over its own available period, on a shared scale; the window averages above are therefore not identical across models.
