Kansas City's forecast for Friday has moved 16°F colder

67°F in the 20261105T00:00Z run, 51°F in the 20261106T18:00Z — 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 Friday, November 13 at 18Z in Kansas City, that trail runs from 67.0°F in the 20261105T00:00Z cycle to 50.6°F in the 20261106T18:00Z — a move of -16.4°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.

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