Interesting observations. It started snowing here about a half hour ago. Just like you, there was no "lead up" by way of flurries or sleet turned to rain. BAM, it just started as a wall of tiny flakes. I cant see the pole lights of my neighbors farm , hes about 1/3 mile away .
Wind's starting to make some noise nd all the sheep and the steers made a bee line for the barns.
Got a fire started in the fireplace, Im watching PAWN STARS, made some brats n onions for supper. Wifes doing the barn watch till 1AM.
