Dallas's forecast for Friday has moved 14°F colder
93°F in the 20261002T00:00Z run, 79°F in the 20261003T18:00Z — the 2nd-largest revision of the 10 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 13°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, October 9 at 21Z in Dallas, that trail runs from 93.0°F in the 20261002T00:00Z cycle to 79.4°F in the 20261003T18:00Z — a move of -13.5°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.
