One of the largest high pressure ridges meteorologists have ever seen – a huge dome extending from northern Mexico across the entire continental US and in a curve from Vancouver to Toronto north through the Prairies – is just arriving. Temperatures are forecast to hit record values or potentially exceed them across all areas of California, but the vast scale of this hot air will affect all growers in all growing areas and speed up growth on many crops while demanding a surge of irrigation water. Citrus growing areas in the desert and the southern Central valley between Fresno and Bakersfield are expected to range from 42 to 46C. There hasn’t been much conversation recently about the California drought because good spring rains raised all the reservoirs to at least 80% of capacity, but the Sierra Snowpack is lower than normal, and what none of these reports cover is the amount of recharge over the winter and spring to the huge aquifers that supply most of the irrigation water. Maybe the notice on the field portable in this picture that Brody took while on a farm tour last week in California says it all – nothing has changed, and if is not getting better.
