Minneapolis's forecast for Tuesday has moved 11°F colder
53°F in the 20261018T00:00Z run, 42°F in the 20261019T18:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 22°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Tuesday, October 27 at 06Z in Minneapolis, that trail runs from 52.8°F in the 20261018T00:00Z cycle to 41.5°F in the 20261019T18:00Z — a move of -11.3°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.
