Denver's forecast for Saturday has moved 9°F warmer
57°F in the 20261016T12:00Z run, 66°F in the 20261017T12:00Z — 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 21°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Saturday, October 24 at 21Z in Denver, that trail runs from 56.8°F in the 20261016T12:00Z cycle to 65.6°F in the 20261017T12:00Z — a move of +8.9°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
