Dallas's forecast for Monday has moved 9°F warmer
67°F in the 20261010T18:00Z run, 76°F in the 20261012T12:00Z — the 2nd-largest revision of the 11 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 16°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Monday, October 19 at 00Z in Dallas, that trail runs from 67.0°F in the 20261010T18:00Z cycle to 76.3°F in the 20261012T12:00Z — a move of +9.2°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.
