61°F in the 20261029T00:00Z run, 67°F in the 20261030T18:00Z — the 3rd-largest revision of the 3 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 17°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, November 6 at 18Z in Nashville, that trail runs from 61.1°F in the 20261029T00:00Z cycle to 67.1°F in the 20261030T18:00Z — a move of +6.1°F across 8 runs.
