78°F in the 20260921T06:00Z run, 70°F in the 20260923T06:00Z — 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 17°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Wednesday, September 30 at 18Z in Kansas City, that trail runs from 78.3°F in the 20260921T06:00Z cycle to 69.9°F in the 20260923T06:00Z — a move of -8.5°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.
