Kansas City's forecast for Saturday has moved 10°F colder

64°F in the 20261031T18:00Z run, 54°F in the 20261102T12:00Z — 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 Saturday, November 7 at 18Z in Kansas City, that trail runs from 64.0°F in the 20261031T18:00Z cycle to 53.9°F in the 20261102T12:00Z — a move of -10.1°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.
