70°F in the 20260913T18:00Z run, 60°F in the 20260915T12:00Z — the 2nd-largest revision of the 6 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 14°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, September 18 at 18Z in Minneapolis, that trail runs from 70.4°F in the 20260913T18:00Z cycle to 59.7°F in the 20260915T12:00Z — a move of -10.7°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.
