Denver's forecast for Friday has moved 9°F warmer
64°F in the 20261014T00:00Z run, 73°F in the 20261015T18:00Z — the 3rd-largest revision of the 7 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 9°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 64.4°F in the 20261014T00:00Z cycle to 72.9°F in the 20261015T18:00Z — a move of +8.5°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.
