42°F in the 20261023T00:00Z run, 55°F in the 20261024T00:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 28°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Saturday, October 31 at 09Z in Minneapolis, that trail runs from 41.9°F in the 20261023T00:00Z cycle to 54.7°F in the 20261024T00:00Z — a move of +12.8°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
