Denver's forecast for Tuesday has moved 6°F colder
44°F in the 20261030T06:00Z run, 38°F in the 20261101T00:00Z — the 3rd-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 17°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Tuesday, November 10 at 12Z in Denver, that trail runs from 44.4°F in the 20261030T06:00Z cycle to 38.0°F in the 20261101T00:00Z — a move of -6.4°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
