Data locationJACKSON HOLE (AWOS) (JAC)11.1 miles from central Jackson · Archive 2024-08-01–2026-07-28

Based on archived raw NBM forecasts compared with observed daily highs and lows near Jackson. Results describe this model archive, not every forecast provider.

How these numbers are calculated

The forecasts are raw NBM median temperature guidance initialized at 12Z. Results include multiple NBM model eras and are retrospective, so they describe this archive rather than guaranteeing future performance.

“Typical miss” is mean absolute error: the average size of the error regardless of direction. Warmer or cooler tendency is signed bias, which can be small even when individual errors are larger.
