Denver's forecast for Tuesday has moved 9°F colder
45°F in the 20261030T00:00Z run, 36°F in the 20261031T18:00Z — 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 18°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 45.2°F in the 20261030T00:00Z cycle to 36.1°F in the 20261031T18:00Z — a move of -9.0°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.
