Temperatures warmed nicely again into the 80s on Monday for much of Iowa. This will likely be the last of the 80s for at least the next week or so, but will it be the last of the 80s this year? The featured chart displays the combination of number of days over 80 degrees each year for Des Moines and the date of the last 80+ degree temperature that year. On average, we are likely to see another 80 degree day in October as about only 20% of years saw their last 80 degree temperature by the end of September. In general, the number of days over 80 does not appear to be a good predictor of the last date. The average date is Oct 10 as well, so there is hope for more really warm weather yet this fall!
