Kansas City's forecast for Saturday has moved 15°F warmer
70°F in the 20260912T06:00Z run, 84°F in the 20260914T00:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 20°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Saturday, September 19 at 18Z in Kansas City, that trail runs from 69.5°F in the 20260912T06:00Z cycle to 84.5°F in the 20260914T00:00Z — a move of +14.9°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.
