76°F in the 20260930T12:00Z run, 87°F in the 20261002T00:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 12°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Monday, October 12 at 00Z in Dallas, that trail runs from 76.0°F in the 20260930T12:00Z cycle to 87.3°F in the 20261002T00:00Z — a move of +11.2°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.
