Ice crystals like cactus needles.
Later in the afternoon Callie and I were snowed upon during our walk. It started as sleet but quickly changed to snow. The road was white by the time we got home and I had to brush snow off the dog's back before taking her into the house. The air flow is shifting today to the south; by Friday we should be having a mini heat wave. Well, maybe a mini not-as-cold wave.
