It literally happened that way.
Friday morning, clear and warm. Friday afternoon, the clouds started coming in -- and it commenced to snow at 4:30 p.m.
By 6 p.m. or so, the snow was sticking.
IF it comes...
I'm not surprised. This is typical for us -- and Colorado. I did get the garden bed of greens and peas covered, and brought in the flowers I bought this week. (Fortunately, they weren't planted yet.)
Temps are down in the 20s. Our power flickered on and off several times last night, but never went completely out. We're warm and snug -- and maybe a bit drowsy. A good day to stay in.
