73°F in the 20260914T18:00Z run, 62°F in the 20260916T12:00Z — the 2nd-largest revision of the 7 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 Monday, September 21 at 21Z in Minneapolis, that trail runs from 73.0°F in the 20260914T18:00Z cycle to 62.1°F in the 20260916T12:00Z — a move of -10.9°F across 8 runs.
