Minneapolis's forecast for Friday has moved 13°F colder
75°F in the 20260913T12:00Z run, 62°F in the 20260915T06:00Z — 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 20°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, September 18 at 21Z in Minneapolis, that trail runs from 74.7°F in the 20260913T12:00Z cycle to 61.6°F in the 20260915T06:00Z — a move of -13.1°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.
