Denver's forecast for Saturday has moved 10°F warmer
57°F in the 20261016T12:00Z run, 67°F in the 20261017T06:00Z — the 2nd-largest revision of the 3 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 17°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 66.9°F in the 20261017T06:00Z — a move of +10.2°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.
