79°F in the 20260909T06:00Z run, 68°F in the 20260910T00:00Z — the 2nd-largest revision of the 6 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 19°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Thursday, September 17 at 15Z in Kansas City, that trail runs from 78.5°F in the 20260909T06:00Z cycle to 68.5°F in the 20260910T00:00Z — a move of -10.1°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.
