Temperatures warmed again nicely on Tuesday making for a three day stretch of excellent weather for most of Iowa. The Des Moines Airport reported 75 degrees at 4 PM. The featured chart presents April average 4 PM temperatures for the site by year along with the long term average and simple linear regression. The plot indicates a warming trend over the years and certainly most of the recent years have been above long term average. This year is a noted exception, but there is still a few days left to pull that average up and the forecast would indicate warmer temperatures through the end of the month.
