Denver's forecast for Wednesday has moved 7°F warmer
52°F in the 20261028T06:00Z run, 60°F in the 20261030T00:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 16°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Wednesday, November 4 at 21Z in Denver, that trail runs from 52.1°F in the 20261028T06:00Z cycle to 59.5°F in the 20261030T00:00Z — a move of +7.4°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
