That is what Fritz the weather guy said on the news last night...hot on Thursday and Friday, in the 100's in the inland areas.
On the plus side, the mornings are always pleasant and it does not get hot until the afternoon. I am not sure I would cancel a trip due to it, as that is simply the high, not the temperature for the entire day. Plan to do outside things in the morning, do some of the inside things with A/C in the afternoon, then take a cool nap/rest before dinner and it will be fine again after dinner.
It is much different here than the muggy, oppressive heat of Orlando, where it gets hot first thing in the morning and never lets up.
Come have fun!
