Daily forecast evolution — 2026-08-19

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 95.0°F , low 76.0°F. · Clear date

Daily high forecast vs actual
