Dallas's forecast for Tuesday has moved 7°F warmer
68°F in the 20261017T18:00Z run, 75°F in the 20261019T00:00Z — 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 5°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Tuesday, October 20 at 01Z in Dallas, that trail runs from 68.0°F in the 20261017T18:00Z cycle to 74.9°F in the 20261019T00:00Z — a move of +6.9°F across 8 runs.
The change is larger than the run's own 10th-to-90th percentile spread — the guidance did not merely narrow, it moved off its previous position.
