Nashville's forecast for Thursday has moved 9°F warmer
49°F in the 20261026T18:00Z run, 59°F in the 20261028T12:00Z — 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 17°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Thursday, November 5 at 06Z in Nashville, that trail runs from 49.4°F in the 20261026T18:00Z cycle to 58.7°F in the 20261028T12:00Z — a move of +9.3°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.
