Minneapolis's forecast for Wednesday has moved 7°F colder
69°F in the 20260915T06:00Z run, 62°F in the 20260917T00:00Z — the 3rd-largest revision of the 3 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 12°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Wednesday, September 23 at 00Z in Minneapolis, that trail runs from 69.2°F in the 20260915T06:00Z cycle to 62.4°F in the 20260917T00:00Z — a move of -6.8°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.
