I am no scientist, but the weather patterns are changing.
The Texas of my youth had school closing storms only once every two years, if we were lucky. The youth today, just don't even know the luck that global warming brings them.
The snow blast of 2011 was in part two today. Not as impressive as last week. It does mean no school, ice covered roads and being locked safely tucked into the house with sloppy sweats. It is glorious!
