[Update 10/13/16] I have added in the remainder rainfall totals for the cropping year. Thornton, WA. had significantly less rainfall for the year than normal. The Thornton rain belt is ≈17"- 19"and 2016 showed 13.78". The SJ-E (my gauge) rain belt is14.67" 2016 showed 16.95".
The Thornton area crops were generally quite good. Our spring standup peas were fantastic.
The SJ-E area crops were spotty, ranging from fantastic to a little above average.
There are many examples that indicate there is more to yield than rainfall total. Weather, as it plays across a field can make or break a yield. We experienced a frost in April and June that had differing effects on fields.
I'm going to start posting rainfall for the two regions we farm. It's very surprising to me, and most unusual that this crop year shows St.John/Ewan area with more moisture than Thornton. Micro climates are certainly playing a part to have this happen. Brackets show a running total for the crop year which starts September 1st.

I look forward to following along. I have a research site between Pendleton and Hermiston where we have historically had one station, but I have added a second as we have two distinct areas at the site where we do research that have about 100ft of difference. It has been fun to monitor the microclimate differences in wind, ETo, and temperature. I can detect inversions quite readily now. Precipitation differences are also obvious but small. It is hard to assess how much is wind impacted and how much is legitimate.
