Minneapolis's forecast for Monday has moved 10°F warmer

65°F in the 20261005T00:00Z run, 75°F in the 20261006T18:00Z — the 3rd-largest revision of the 10 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 23°F.

Successive cycles do not merely refresh a forecast; they leave a trail. For Monday, October 12 at 00Z in Minneapolis, that trail runs from 65.0°F in the 20261005T00:00Z cycle to 75.2°F in the 20261006T18:00Z — a move of +10.2°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.
