There is another chance of precipitation coming up this weekend. At northern and central VA, the chance of thunderstorms are 30-40% on both Saturday and Sunday, and at eastern shore, the chance is about 30% on Sunday.
Most of northern VA probably received more than 1 inch of rain during the last series of rain, and depends on how hard it rained, your protection may have been washed out. A typical rule of thumb for fungicide application timing is "2 weeks or 1 inch of rain whichever comes first", but during the spring when grape shoots grows rapidly, you may need to adjust the schedule based on the growth, thus my recommendation is 7-10 days schedule up to 1 month after bloom, then 14 days.
Plus, there is a frost advisory issued for tomorrow morning. I hope it won't happen...
