Denver's forecast for Sunday has moved 14°F warmer
62°F in the 20260925T06:00Z run, 77°F in the 20260927T00:00Z — the 2nd-largest revision of the 9 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 15°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Sunday, October 4 at 00Z in Denver, that trail runs from 62.2°F in the 20260925T06:00Z cycle to 76.7°F in the 20260927T00:00Z — a move of +14.5°F across 8 runs.
The change is about half the run's 10th-to-90th percentile spread, so the earlier forecast is still inside the current range of outcomes.
