Only initial date of record event is shown and hourly ties were not considered
Very warm air is surging into Iowa this Saturday with numerous record high temperatures being set. Des Moines set its record high today by reporting 78 degrees at 12:35 PM. Is it unusual for a record high to be set just after noon? The featured chart provides an estimate of the time of day record high and record low temperatures occurred at. The daily records are from a different dataset than the hourly temperature archive, so some estimates were done and a constraint that the extreme hourly temperature was within 4 degrees of the record temperature. Having a record high near 1 PM has happened previously, but that won't put a damper on today.

The lone blue dot (record low) shown at 5 PM on 25 Sep 1942 appears to be legitimate estimate.

Voting:
Good = 42
Bad = 13
