51°F in the 20261012T18:00Z run, 62°F in the 20261014T12:00Z — the 3rd-largest revision of the 8 cities on the roster that moved at all. 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 Wednesday, October 21 at 18Z in Salt Lake City, that trail runs from 50.6°F in the 20261012T18:00Z cycle to 61.8°F in the 20261014T12:00Z — a move of +11.2°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.
