70°F in the 20260916T18:00Z run, 61°F in the 20260918T12:00Z — the 3rd-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 12°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Thursday, September 24 at 15Z in Kansas City, that trail runs from 69.9°F in the 20260916T18:00Z cycle to 60.9°F in the 20260918T12:00Z — 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.
