Hi!
We just got back tonight and spent Sunday, Monday and Wednesday in the parks. While they were far from empty, all of the waits were very tolerable. The most we waited for any attraction was 20 minutes and many were walk-ons. I saw many fast-pass lines closed because the waits were only 5 minutes or so. The weather was sunny and hot (in the low 90's), although I do remember seeing rain in the forecast for the end of the weekend and first of next week. Just pack your ponchos and enjoy the lighter crowds if the rains do come. Have fun!!!
