Posted: 28 Sep 2026 05:30 AM, Views: 439
The continued near daily rainfalls this September continued over the weekend with a number of rounds of light rainfall. The featured calendar chart presents daily precipitation reports for the Des Moines airport so far this September. Only two dry days are shown over the past two weeks and even only four over the past three weeks. More rain is in the forecast for this week as last few days of the month will take a run at attempting to set a September precipitation record for Des Moines (still need ~1.5 inches more).
