Most likely it is due to Houston building up and also asphalt runways nearby at the airport.

WXMan57 raises a very good point from another topic I created about 100F days and major hurricane landfalls.wxman57 wrote:I believe that we're seeing more 100F days lately because the thermometer exposure is different from the "old day". With lots more concrete around the city, there's a heat island effect that wasn't in existence much of the last century (until the 1970s). There are just a lot more heat sources than there were in the first half of last century.
In addition, I've seen studies that suggest the change to a new material for instrument shelters may have contributed to most of the temperature rise last century attributed to global warming.
