82°F in the 20260910T18:00Z run, 71°F in the 20260912T12:00Z — the largest revision of any city on the roster. 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 Monday, September 14 at 00Z in Kansas City, that trail runs from 82.0°F in the 20260910T18:00Z cycle to 71.3°F in the 20260912T12:00Z — a move of -10.6°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.
