Kansas City's forecast for Tuesday has moved 10°F warmer

74°F in the 20261008T00:00Z run, 84°F in the 20261009T18:00Z — the 2nd-largest revision of the 8 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 16°F.

Successive cycles do not merely refresh a forecast; they leave a trail. For Tuesday, October 13 at 21Z in Kansas City, that trail runs from 73.8°F in the 20261008T00:00Z cycle to 83.9°F in the 20261009T18:00Z — 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.
