68°F in the 20260916T00:00Z run, 59°F in the 20260917T18:00Z — the 3rd-largest revision of the 8 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 12°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Wednesday, September 23 at 15Z in Kansas City, that trail runs from 68.3°F in the 20260916T00:00Z cycle to 59.5°F in the 20260917T18:00Z — a move of -8.8°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.
