Denver's forecast for Friday has moved 7°F colder
55°F in the 20261028T00:00Z run, 47°F in the 20261029T18:00Z — the 2nd-largest revision of the 5 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 11°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, November 6 at 00Z in Denver, that trail runs from 54.7°F in the 20261028T00:00Z cycle to 47.3°F in the 20261029T18:00Z — a move of -7.5°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.
