88°F in the 20260921T18:00Z run, 78°F in the 20260923T18:00Z — 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 18°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Saturday, October 3 at 00Z in Dallas, that trail runs from 88.5°F in the 20260921T18:00Z cycle to 78.1°F in the 20260923T18:00Z — a move of -10.3°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.
