Dallas's forecast for Tuesday has moved 9°F warmer
63°F in the 20261008T18:00Z run, 72°F in the 20261010T00:00Z — the largest revision of any city on the roster. 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 Tuesday, October 20 at 06Z in Dallas, that trail runs from 63.0°F in the 20261008T18:00Z cycle to 72.1°F in the 20261010T00:00Z — a move of +9.1°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
