MILEPOST 1107
Minneapolis's forecast for Monday has moved 12°F colder
74°F in the 20260914T12:00Z run, 62°F in the 20260916T06:00Z — the largest revision of any city on the roster. 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 Monday, September 21 at 21Z in Minneapolis, that trail runs from 73.5°F in the 20260914T12:00Z cycle to 61.6°F in the 20260916T06:00Z — a move of -12.0°F across 8 runs.
The change is larger than the run's own 10th-to-90th percentile spread — the guidance did not merely narrow, it moved off its previous position.
