Dallas's forecast for Tuesday has moved 9°F colder
66°F in the 20261013T12:00Z run, 57°F in the 20261015T06:00Z — the 3rd-largest revision of the 9 cities on the roster that moved at all. 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 Tuesday, October 20 at 12Z in Dallas, that trail runs from 66.2°F in the 20261013T12:00Z cycle to 57.3°F in the 20261015T06:00Z — a move of -8.9°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.
