For a long drought regarding any northerly wind the past two weeks, this might trigger migrants on the move and Friday prospectively favorable for bird numbers uptick. It helps too to see the setting sun for birds to orient themselves but with no good wind for awhile, they'll say the heck with it Lets go! :-) it will be a wet thunderous commute though.
