The weather in Southwest Virginia June 20, 2020

I'm renewing my vows and having an outdoor wedding June 20, 2020. Are you able to give me a projected idea of what the weather will be for my region then? If not, how far advance are you able to tell me in case I have to check back with you?

Also, which month in the year between April and June does it rain the least in southwest Virginia? Just in case we decide to move our date.
