59°F in the 20261012T12:00Z run, 69°F in the 20261014T06:00Z — the 3rd-largest revision of the 9 cities on the roster that moved at all. The current run's 10th-to-90th percentile spread at that hour is 13°F.
Successive cycles do not merely refresh a forecast; they leave a trail. For Saturday, October 17 at 03Z in New York, that trail runs from 59.3°F in the 20261012T12:00Z cycle to 69.0°F in the 20261014T06:00Z — a move of +9.7°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.
