Did the afternoon report's high hold?

On 182 days from May 1, 2026 to Oct 30, 2026, the NWS's afternoon preliminary report (usually "as of 5 PM" local time) had the same high as the final report on 169 of 182 days (93%). The final report came in higher on 12 and lower on 1.

Every one of those 12 higher finals put the high after the 5 PM cutoff. A final lower than the afternoon report means a reading was corrected or removed in between (1 day).
