Minneapolis's forecast for Saturday has moved 10°F colder

39°F in the 20261106T12:00Z run, 30°F in the 20261108T06:00Z — 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, November 14 at 12Z in Minneapolis, that trail runs from 39.4°F in the 20261106T12:00Z cycle to 29.9°F in the 20261108T06:00Z — a move of -9.6°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.

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