New York's forecast for Wednesday has moved 10°F colder
62°F in the 20261006T06:00Z run, 52°F in the 20261007T12:00Z — the 2nd-largest revision of the 10 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 18°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Wednesday, October 14 at 15Z in New York, that trail runs from 62.0°F in the 20261006T06:00Z cycle to 51.9°F in the 20261007T12:00Z — a move of -10.1°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.
