Posted: 10 Nov 2026 05:30 AM, Views: 1759
Yesterday's daily feature denoted that the Des Moines Airport weather sensor has yet to breach 32°F this fall season and is approaching a record for latest such first date. Today's featured chart looks into the longest consecutive day streak with a low temperature at or above (AOA) 32°F. The chart presents the longest such streak by day of the year. The right hand table lists out the longest events. This year's period comes in as the longest on record for the site with the last sub 32°F temperature occurring on 28 March. The forecast for Friday and Saturday morning continues to look like when this streak will end.
