The featured chart displays the daily high and low temperature climatology for Des Moines. While we have past the warmest days of the year on average, the trend for August is more flat than it is down. It is kind of interesting to see how the slide downwards really gets going in September. The month of August features elevated humidity levels, mature agricultural crops, and warm ground temperatures, all of which help to keep temperatures from fluctuating too wildly. The current near term forecast is a case in point with highs and lows about the same each day.
