Fall, does not feel like it

I heard that was soposed to be a cold front that would come through Katy.  Yesterday it  felt like there was a good cold front, but here's something weird today on the wheather channel said the high was 68 degrees and boy was it hot . I went out and it was so hot that I had to take off my jacket and roll up my sleeves. I even saw a wasp. The whether man was wrong. It might be in the 50's, but it feels like its in the 90's. WHOA!
