Denver's forecast for Friday has moved 12°F warmer
58°F in the 20261012T18:00Z run, 70°F in the 20261014T12:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 20°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, October 23 at 00Z in Denver, that trail runs from 58.2°F in the 20261012T18:00Z cycle to 69.7°F in the 20261014T12:00Z — a move of +11.5°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.
