58°F in the 20260910T12:00Z run, 69°F in the 20260912T06:00Z — the 2nd-largest revision of the 10 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 20°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, September 18 at 12Z in Kansas City, that trail runs from 57.8°F in the 20260910T12:00Z cycle to 69.3°F in the 20260912T06:00Z — a move of +11.5°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.
