The heat is on for the Memorial Day weekend and temperatures on Saturday were some of the warmest on record for May. The featured table shows the hourly temperature reports from the Des Moines Airport and the previous May date with as warm or warmer temperature for that hour. The noon and 3 PM temperatures were the warmest on record, which dates back to the early 1930s for hourly temperature reports. Today will be even warmer yet with some locations taking a run at 100 degrees.
