59°F in the 20261015T12:00Z run, 70°F in the 20261017T00:00Z — the 2nd-largest revision of the 4 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 11°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Tuesday, October 27 at 00Z in Denver, that trail runs from 58.9°F in the 20261015T12:00Z cycle to 69.8°F in the 20261017T00:00Z — a move of +10.9°F across 8 runs.
The change is larger than the run's own 10th-to-90th percentile spread — the guidance did not merely narrow, it moved off its previous position.
