Not so warm in south Texas

I'm on my last trip of the fall travel season, and frankly I'm rather disappointed. The people are great, I've got a bay front room and have had fun thus far. The major issue here is the freakin' weather. I picked this trip almost exclusively for the nice weather potential. Seriously, who doesn't want to go to Corpus Christi in December? It's all nice and warm and sunny.... or not. No, it was lovely when I got here on Wednesday, about 85 degrees, sunny, a light breeze. I wore my flip flops and walked around town - just great! All that ended about the time I went to bed that night. The wind woke me up repeatedly, it got terribly cold out, and today I didn't see the sun at all. Granted, it's better than the cold and wind in DC (cause there's no bay front room) and it is probably 10 to 20 degrees warmer. I'm outta here tomorrow afternoon, and of course it's supposed to warm up over the weekend. I suppose this is what I get for planning business travel around my personal desires.
