Kansas City's forecast for Monday has moved 7°F warmer

72°F in the 20261004T12:00Z run, 79°F in the 20261005T00:00Z — the 2nd-largest revision of the 2 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 26°F.

Successive cycles do not merely refresh a forecast; they leave a trail. For Monday, October 12 at 21Z in Kansas City, that trail runs from 71.7°F in the 20261004T12:00Z cycle to 78.5°F in the 20261005T00:00Z — a move of +6.8°F across 8 runs.

The change sits well inside the run's own spread, which is the guidance converging rather than reversing.

Model NBM-QMD, via api.weather.city /v1/history. Percentiles are the same run's own.
