Disease risks from this week's rain

I was out to the eastern shore for an extension trip and missed the rain event!  During 8/23-24, Winchester area received around 0.29 inches of rain.  The event started from around 5PM on 23rd and ended around 4:30 AM on 24th.  The RH was above 90% until noon or so.  Thus, this event accounted for 20hr of wet event with an average temperature around 68F.  It was warm and long enough for both downy mildew and Botrytis.

So far, no rain is in this weekend's forecast.
