Plenty of Summer Left

Posted: 26 Jul 2019 05:41 AM

The featured chart depicts the date each year that ended the warmest 91 day stretch for Des Moines. A linear regression is fitted to the data along with the simple average date of September 7th shown. So while the signs of the impending fall season are increasing each day, there is still likely an entire month of summer left if you consider this metric as the delimiter of the seasons! The near term forecast certainly will feel like summer, but temperatures will be a bit below average next week.

Good = 11
Bad = 0
