MILEPOST 1289
Minneapolis's forecast for Sunday has moved 12°F warmer
61°F in the 20261002T12:00Z run, 73°F in the 20261004T06:00Z — the largest revision of any city on the roster. The current run's 10th-to-90th percentile spread at that hour is 20°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Sunday, October 11 at 18Z in Minneapolis, that trail runs from 60.9°F in the 20261002T12:00Z cycle to 72.7°F in the 20261004T06:00Z — a move of +11.8°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.
