Accumulated ET at Avondale was much below average for the 2017 growing season, and precipitation accumulations for the growing season were almost 2 inches above average. From mid-June to mid-July, daily ET values were regularly over a quarter inch. But aside from that time period, daily ET accumulations mainly remained below a quarter inch.

In general, negative ET anomalies align well with below average temperature anomalies and below average solar radiation days. Even with hot summer days, there were no prolonged periods of much above average temperatures during the growing season that would amplify ET. Additionally, for the first half of the growing season, most days were less windy than average. The result: even during hotter and sunny days, there wasn't as much blowing wind to "pick up" and evaporate the moisture on the crops.

The 2017 growing season ended with a very cool, wet, and cloudy week, with ET values much below average.
