Kansas City's forecast for Tuesday has moved 17°F warmer
68°F in the 20260909T18:00Z run, 85°F in the 20260911T12:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 13°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Tuesday, September 15 at 18Z in Kansas City, that trail runs from 68.5°F in the 20260909T18:00Z cycle to 85.0°F in the 20260911T12:00Z — a move of +16.6°F across 8 runs.
The change is larger than the run's own 10th-to-90th percentile spread — the guidance did not merely narrow, it moved off its previous position.
