Minneapolis's forecast for Wednesday has moved 8°F colder
54°F in the 20261029T00:00Z run, 46°F in the 20261030T18:00Z — the largest revision of any city on the roster. 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 Wednesday, November 4 at 06Z in Minneapolis, that trail runs from 53.8°F in the 20261029T00:00Z cycle to 45.5°F in the 20261030T18:00Z — a move of -8.2°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
