Looking forward to the cool down no matter how short lived it will be.  Rainfall here for September was better than for most places.  Received 3.32" for the month.  That was mostly from the 2.15" that fell on 9/5, surprise over performer.  Rest of the month was scattered light events.  Hopefully October can deliver more widespread moderate to heavier totals but my expectations are low.
