We woke up to a light rain this morning but so far it’s soaked into the ground.  It looks like the first round of heavy weather went south of us.  There is the potential for a few storms this afternoon but they’re going to be isolated so we’ll have to wait and see.  It’s nice to see the clouds and light rain after the last few days of sun.  This has been The Summer of Olives and this definitely feels like another olive day.  Hopefully the weather pushes a few more sulphurs, isonychias, golden drakes, and cahills.  We’ve seen isolated decent hatching of those but it would be nice to see it river wide.  These humid days always have to potential to bring out the flying ants too.
