63°F in the 20261020T18:00Z run, 70°F in the 20261022T12:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 22°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Tuesday, October 27 at 21Z in Kansas City, that trail runs from 62.7°F in the 20261020T18:00Z cycle to 70.2°F in the 20261022T12:00Z — a move of +7.6°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
