When you set an all time December record high temperature, like Des Moines did back on the 15th, of course the daily high record for that day is beat as well. The remarkable aspect of the daily record high temperature beat was the amount greater than the previous record for the date. The featured chart presents the dates over the period of record for Des Moines where a new daily max high or daily min low were established. The previous record was 59 degrees with the new record being 74, so a beat of 15 degrees! The chart indicates this being the largest beat since another 15 degree beat back on 30 May 1934!
