@chai2,
All I know about snow in Austin is the 1920ish snow that my grandmother told of. They had moved there a few months before from a colder climate and for unknown reasons had brought along a sled. They were from her remembering the only folks in town with a sled.
She left town soon after and the rest is the story of how I eventually came to be...
Enjoy the snow, maybe some will adhere to grass and trees and even car tops so children can have some fun (maybe even the occasional adult can join in on the merriment).
