Daily forecast evolution — 2026-08-21

How the forecasted daily high and low for this local calendar day changed each time we re-collected, until the day ended. Lead time is hours until local midnight (end of day). After the day’s high (or low) has already been observed, later snapshots freeze at max/min of remaining forecast hours and observations so far — so evening “highs” do not collapse to leftover cooler hours. Final actuals: high 71.0°F , low 66.0°F. · Clear date

Daily high forecast vs actual

Each point is the expected daily high at that collection time (remaining forecast hours ∪ observations so far). After the peak is observed, the high freezes instead of dropping with evening hours. Lead time is hours until local midnight. Green dashed = finalized actual high.
