At Winchester, we had a series of thunderstorms went through the area from 3:30 to 6:00 am or so (0.47 inches). The relative humidity was above 90% until around 7:30 am. Thus, it was about 5 hours of wetness with average temperature of 68-69F. It was an infection event for Phomopsis (light infection) and downy mildew. In addition, warm temperature and high RH probably promoted downy mildew to produce spores.

As I type in this post, the sky is getting darker… I guess we will have another thunderstorm this evening.
