Minneapolis's forecast for Sunday has moved 6°F colder
60°F in the 20261019T12:00Z run, 54°F in the 20261021T06:00Z — the 3rd-largest revision of the 4 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 14°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Sunday, October 25 at 21Z in Minneapolis, that trail runs from 60.4°F in the 20261019T12:00Z cycle to 54.3°F in the 20261021T06:00Z — a move of -6.1°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
