The persistent La Niña continues to create weather troubles over much of the US with the ongoing drought being difficult to break. With just a few days left in the fall season of September, October, and November, it is a good time to check in on the relationship between the El Niño index and fall season average temperatures and precipitation. Since the impact of El Niño is not instantaneous, the plot compares the August value with the subsequent fall season totals for Iowa. The relationship is not necessarily direct nor strong during the fall season, but general trend is for La Niña falls to be drier and a bit warmer than average.
