Dallas's forecast for Friday has moved 7°F warmer
66°F in the 20261003T06:00Z run, 73°F in the 20261005T00:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 11°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, October 9 at 09Z in Dallas, that trail runs from 66.1°F in the 20261003T06:00Z cycle to 73.4°F in the 20261005T00:00Z — a move of +7.3°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.
