Most of northern VA did not see precipitation until very late last night (~1:30 am). It seems that the storm system missed most of us, unless you are in West Virginia. At Winchester location, a series of rain started around 1:20 am, then there were several precipitation intermittently, and it resulted in a total of 0.34 inches of rain. The relatively humidity was stay high (>90%) until 10:00 am. Thus, if you count the very first rain, we observed around 8.7 hours of wetness. The average temperature during this event was around 73F.
This was a borderline event for black rot and Phomopsis because they requires about 8 hours at this temperature. For downy mildew, the temperature range was optimal, thus, the infection risk was probably high. Also, it was long enough for powdery mildew to discharge ascospores.
