As I write this in the first week of June, an unusual weather system brought rain showers--including thunder and lightning--to Northern California. Despite the area's need for water, the untimely weather was ominous for winegrape growers for multiple reasons. Varieties in some places hadn't finished bloom; high humidity and temperatures in the 70s increased mildew pressure; and possibly most ominous of all: The lightning suggested that last summer's wildfires were not a once-in-a-lifetime event.
