Successive cycles do not merely refresh a forecast; they leave a trail. For Friday, November 13 at 18Z in New York, that trail runs from 54.2°F in the 20261103T06:00Z cycle to 47.7°F in the 20261105T00:00Z — a move of -6.5°F across 8 runs.
The change sits well inside the run's own spread, which is the guidance converging rather than reversing.
