Minneapolis's forecast for Sunday has moved 8°F colder
61°F in the 20261019T06:00Z run, 52°F in the 20261021T00:00Z — the 3rd-largest revision of the 3 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 16°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 60.8°F in the 20261019T06:00Z cycle to 52.5°F in the 20261021T00:00Z — a move of -8.3°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.
