Dallas's forecast for Friday has moved 8°F warmer
68°F in the 20260921T00:00Z run, 76°F in the 20260922T18:00Z — the 3rd-largest revision of the 6 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 Friday, October 2 at 12Z in Dallas, that trail runs from 67.7°F in the 20260921T00:00Z cycle to 75.8°F in the 20260922T18:00Z — a move of +8.1°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
