Denver's forecast for Sunday has moved 6°F warmer
60°F in the 20261102T06:00Z run, 66°F in the 20261104T00:00Z — the 2nd-largest revision of the 2 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 6°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Sunday, November 8 at 21Z in Denver, that trail runs from 60.2°F in the 20261102T06:00Z cycle to 66.5°F in the 20261104T00:00Z — a move of +6.3°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.
