For the last two days the sky has been full of billowy clouds. I am not sure if it is the remnants of Hurricane Harvey or Autumn is coming early this year, but the temperatures have also dropped from the 80's (upper 20s C) to the 60s (teens C).
@maggiemae - If they are the remnants of Harvey they are pretty depleted by now. We are getting those sporadic rains where you get rain in small areas.
