70°F in the 20260910T00:00Z run, 84°F in the 20260911T18:00Z — 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 15°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Wednesday, September 16 at 18Z in Kansas City, that trail runs from 70.4°F in the 20260910T00:00Z cycle to 83.8°F in the 20260911T18:00Z — a move of +13.3°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.
