Weather is all over the place.  Was clear a few days ago.  yesterday it was 40% chance.  this morning was slight chance, but rain in a.m.  Now it says all clear. Most likely with a 90degree day, they are "guessing" on an afternoon shower due to the heat. I'm pumped.  Just hope no more than a couple of sessions is rained out.  I don't ride the track in the rain.
