Bad: 0 Abstain: 0
The last days of September have been quite warm with record high temperatures set or tied at a number of locations over the Midwestern US on Monday. For Des Moines, Monday was the fourth consecutive day with a high temperature of a least 84°F. The present forecast looks to continue such warm daily high temperatures into at least Friday, which would be a eight day streak. The featured chart presents the frequency of a given day of the year participating within such a streak for Des Moines with the earliest and latest such events listed to the side. So having such an event end on 3 October would best the previous latest such streak by about ten days.
