Successive cycles do not merely refresh a forecast; they leave a trail. For Saturday, November 14 at 18Z in Denver, that trail runs from 55.2°F in the 20261110T12:00Z cycle to 47.8°F in the 20261112T06:00Z — a move of -7.4°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.
