Denver's forecast for Sunday has moved 8°F warmer
59°F in the 20261101T12:00Z run, 66°F in the 20261103T06:00Z — 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 10°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Sunday, November 8 at 21Z in Denver, that trail runs from 58.8°F in the 20261101T12:00Z cycle to 66.4°F in the 20261103T06:00Z — a move of +7.6°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.
