HII The Ledger MILEPOST 1527

Guidance has run 6.7°F warm at HII for a month

The mean signed residual across 338 pairs is +6.65°F, against +0.09°F averaged over all 84 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 29–October 29, 2026, it lands +6.65°F from the report, across 338 pairs — the largest standing lean of any of the 84 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.
