Snow in Houston?

Wow! It's snowing in Houston! Check out some of the pictures on www.KHOU.com. I lived in Houston for a few years back in the '80's. There is even a lot of snow along the coast, which I find surprising, since the temperature should be a few degrees warmer there. The city took a lot of preventive measures by spraying deicer along the highways yesterday. Hopefully the roads will be clear for all of the cruise passengers embarking and disembarking over the weekend. If not, the trip from the airport to Galveston or the ship channel could turn into an all day affair!
