Minneapolis's forecast for Tuesday has moved 13°F colder
52°F in the 20261018T12:00Z run, 38°F in the 20261020T06:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 20°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Tuesday, October 27 at 12Z in Minneapolis, that trail runs from 51.6°F in the 20261018T12:00Z cycle to 38.2°F in the 20261020T06:00Z — a move of -13.5°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.
