Successive cycles do not merely refresh a forecast; they leave a trail. For Tuesday, September 15 at 18Z in Kansas City, that trail runs from 71.5°F in the 20260909T12:00Z cycle to 84.8°F in the 20260911T06:00Z — a move of +13.3°F across 8 runs.
The change is larger than the run's own 10th-to-90th percentile spread — the guidance did not merely narrow, it moved off its previous position.
