Minneapolis's forecast for Saturday has moved 9°F warmer
54°F in the 20260912T12:00Z run, 64°F in the 20260914T12:00Z — the 3rd-largest revision of the 9 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, September 19 at 12Z in Minneapolis, that trail runs from 54.4°F in the 20260912T12:00Z cycle to 63.7°F in the 20260914T12:00Z — a move of +9.2°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.
