Two months ago, Hurricane Ike ravaged Galveston Island. Today it snowed there. Two months. Today I see it's snowing in south Louisiana. Snow on the bayou.
Not only is it a rarity to have snow on Galveston (I really don't know about Louisiana, but I'm pretty sure it's just as rare there), but for snow to fall in December is almost unheard of.
I grew up in Houston. The few times I saw snow as a child were usually in February, maybe January, but always after the new year. Mom said we didn't do white for Christmas. More likely, it was too hot to wear that new sweater.
Mother Nature is a weird chick.
