Longer answer, don't count on anybody's 10 day forecast as being anything more than a general guideline of the conditions you may run into while there. This time of year, you are best off packing layers. That way some combination of clothing (shirt/sweatshirt/windbreaker) will keep you comfortable.
I usually check out the Orlando Sentinel on-line before we go. I figure if anybody knows they should. I'll find out just how accurate they are in 16 more days!
We're planning on layering on top, but don't know if we should pack more long pants, shorts, capris, etc. I only have so much room, so I can't bring a plethora of each.
