Saturday was dumb luck or whatever you want to call it - there was plenty of moisture around but we just couldn't score.
Sunday never felt like it was our day - from very early on, it seemed...obvious that it was going to be a far eastern PA event. CTP "admitted' they extended the watch for continuity and allowed for any storm that did form/hit could have contained a torrential downpour.
If they hadn't issued the watch on Saturday I highly doubt one would have been issued for Sunday alone.
