Kansas City's forecast for Friday has moved 12°F colder

67°F in the 20261104T18:00Z run, 55°F in the 20261106T12:00Z — the 2nd-largest revision of the 6 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 23°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 67.4°F in the 20261104T18:00Z cycle to 55.3°F in the 20261106T12:00Z — a move of -12.1°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.
