recognizing a pattern

Here in Colorado there is a two day run up before a big snow storm. Day one is the warm before the storm. That was Tuesday when I posted a sunshiny, blue sky day. Day two is the blow before the snow. My blip yesterday was of wind blowing a small amount of snow off a roof. So today should be the big snow storm, right? Well this is all the snow we got! The temperature is still cold, but the sun is out.
