Daily forecast evolution — 2026-10-26

How the forecasted daily high and low for this local calendar day changed each time we re-collected, until the day ended. The series starts once the hourly window covers the date (not the first overnight hour). 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 85.0°F , low 61.0°F. · Clear date

Daily high / low

Earliest forecast that already covers the local date (morning low and afternoon high), not the first overnight hour at the edge of the hourly window, vs finalized calendar-day max/min (only after the local day ends). Click a date to see how the high/low forecast evolved toward the actual.
