Minneapolis's forecast for Friday has moved 7°F colder

42°F in the 20261106T06:00Z run, 35°F in the 20261108T00:00Z — the 2nd-largest revision of the 5 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 Friday, November 13 at 15Z in Minneapolis, that trail runs from 42.4°F in the 20261106T06:00Z cycle to 34.9°F in the 20261108T00:00Z — a move of -7.5°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.
