Minneapolis's forecast for Thursday has moved 7°F colder
71°F in the 20260918T12:00Z run, 64°F in the 20260920T06:00Z — 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 8°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Thursday, September 24 at 21Z in Minneapolis, that trail runs from 70.6°F in the 20260918T12:00Z cycle to 64.0°F in the 20260920T06:00Z — a move of -6.6°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.
