Minneapolis's forecast for Monday has moved 7°F warmer

52°F in the 20261102T00:00Z run, 59°F in the 20261103T18:00Z — 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 Monday, November 9 at 21Z in Minneapolis, that trail runs from 52.1°F in the 20261102T00:00Z cycle to 59.0°F in the 20261103T18:00Z — a move of +6.9°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.
