Guidance has run 4.2°F warm at HII for a month
The mean signed residual across 906 pairs is +4.20°F, against +0.18°F averaged over all 83 stations with enough samples to score. A bias is not an error the reader can ignore — it is one they can correct for.
Mean absolute error says how far the forecast lands from the observation; the signed mean says which side it lands on. At HII over September 22–October 22, 2026, it lands +4.20°F from the report, across 906 pairs — the largest standing lean of any of the 83 stations currently carrying enough samples.
ASOS reports at :53 and the forecast is stamped on the hour, so a forecast is paired with the nearest observation within 30 minutes and otherwise left unscored.
