On Friday, Des Moines failed to reach a high temperature of at least 70 degrees. This snapped the streak of 139 straight days with a daily high temperature of at least 70 degrees. The featured chart presents the yearly maximum streak of days along with the top twenty longest streaks. It is certainly interesting to see so many of the recent years show in the top twenty and is likely indicative of the increasing heat island effect as well as increasing temperatures from climate change. While temperatures will start off the week nice for this time of year, it appears 70s will be just out of reach.
