Minneapolis's forecast for Saturday has moved 12°F colder
56°F in the 20261025T12:00Z run, 44°F in the 20261027T06:00Z — the 3rd-largest revision of the 8 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 11°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Saturday, October 31 at 12Z in Minneapolis, that trail runs from 55.5°F in the 20261025T12:00Z cycle to 43.6°F in the 20261027T06:00Z — a move of -12.0°F across 8 runs.
The change is larger than the run's own 10th-to-90th percentile spread — the guidance did not merely narrow, it moved off its previous position.
