70°F in the 20261007T00:00Z run, 57°F in the 20261008T18:00Z — the 2nd-largest revision of the 10 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 21°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Saturday, October 17 at 12Z in Dallas, that trail runs from 69.7°F in the 20261007T00:00Z cycle to 57.3°F in the 20261008T18:00Z — a move of -12.4°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.
