Nashville's forecast for Thursday has moved 6°F colder
58°F in the 20261031T06:00Z run, 51°F in the 20261102T00:00Z — the 3rd-largest revision of the 5 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 8°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Thursday, November 5 at 09Z in Nashville, that trail runs from 57.7°F in the 20261031T06:00Z cycle to 51.3°F in the 20261102T00:00Z — a move of -6.4°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.
