I thought I posted it, but apparently I did not!  Winchester area received two showers on 8th (Friday), both events were short, and temperature during the events were about 70F.  The first event was longer (~5 hours, but the amount of precipitation was very small (0.02 inches total).  The second event was short (~3 hours), and it was a thunderstorm.  It was downy mildew infection events, but since previous two days were relatively dry, it might not be a big risk.
