Minneapolis's forecast for Thursday has moved 6°F colder

57°F in the 20261103T00:00Z run, 51°F in the 20261104T18:00Z — 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 14°F.

Successive cycles do not merely refresh a forecast; they leave a trail. For Thursday, November 12 at 18Z in Minneapolis, that trail runs from 56.9°F in the 20261103T00:00Z cycle to 50.6°F in the 20261104T18:00Z — a move of -6.3°F across 8 runs.

The change sits well inside the run's own spread, which is the guidance converging rather than reversing.

Model NBM-QMD, via api.weather.city /v1/history. Percentiles are the same run's own.
