Atlanta's forecast for Saturday has moved 8°F colder
68°F in the 20261012T00:00Z run, 60°F in the 20261013T18:00Z — the 3rd-largest revision of the 6 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 Atlanta, that trail runs from 68.1°F in the 20261012T00:00Z cycle to 59.6°F in the 20261013T18:00Z — a move of -8.5°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.
