With today being the last day of a fall season encompassing the months of September, October, and November, it is a good time to look at summary stats in comparison to the El Nino 3.4 Index as shown by the featured chart. The left panel presents the yearly combination of average temperature and precipitation for Iowa with the color of the dots representing the August El Nino 3.4 Index value. The two right panels present the direct comparison between the index and the Iowa value. The 2020 value for Iowa comes in close to average for both temperature and precipitation. The La Nina condition this fall is still developing and stronger influences for our weather may be more likely toward later in the cold season.
