if you flew on Christmas day, there was a snow storm here in Dallas, while many areas of the country can handle more snow then we got on the 25th, Dallas does not have the equiptment either in the city or the airport for more then 2 inches of snow (we rarely get any snow here) so when it does hit, it cripples the city.
To show you how strange Texas weather is, we had snow in Dallas and in north Houston the tornodo sirens were going about off about 11am.
Texas don't like the weather just wait a few minutes it will change
