WE have gone twice during this time. Both times the weather was great!! It was in the low 70's in the day, low 60's at night. PERFECT! Also, it's the dry season, so we didn't have any rain. A couple days it was in the low 80's.
Personally, that was a little to hot for me. I hate hot weather. I sweat to easy.
Many people say to pack for any weather, but I never pack more than a sweatshirt or light jacket for early morning and evening. One pair of jeans, and I wear capris the rest of the time. My DD9 and DH wore shorts, but I don't like them so I stuck with capris.
I don't bother packing heavy clothes, coats or gloves. If I'm that cold I will just buy another Disney sweatshirt.

I usually buy a sweatshirt as a souvenier anyway.
Have fun, it's a GREAT time to go. The only time I will go anymore. Also, the crowds are always low. Never waited more than 10 minutes for anything. Still get your Fastpasses for big rides (Soarin', Everest, etc....) but anything else is usually short lines. We walked right onto Tower of Terror at 11:00 am one day, andturned tirght around and got back on. Same with RNR.
