Successive cycles do not merely refresh a forecast; they leave a trail. For Thursday, September 24 at 12Z in Kansas City, that trail runs from 63.2°F in the 20260917T06:00Z cycle to 56.4°F in the 20260919T00:00Z — a move of -6.8°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.
