Dallas's forecast for Friday has moved 8°F colder
79°F in the 20261024T18:00Z run, 71°F in the 20261026T12:00Z — the 3rd-largest revision of the 5 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 14°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, October 30 at 21Z in Dallas, that trail runs from 79.3°F in the 20261024T18:00Z cycle to 71.1°F in the 20261026T12:00Z — a move of -8.2°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.
