Unfortunately, the only site in Texas (that I am aware of) that collects data and calculates chilling hours is our Research and Extension Center in Overton, TX (see below). I have tried to find detailed historical weather data for other sites so I can calculate average chilling hours and have been unsuccessful. You might review the weather service link that I provided below. You might ask the local airport or other site for a copy of their weather data, but you have to figure out how to calculate the chilling hours from raw data - you might see if the Overton Center could help if you are able to get raw weather data. Good luck.
