3rd snow event?
Sorry, forgot to hit "post this" and just saved it. Was written 12/30/09.Well, we had some more snow again yesterday afternoon (12/29) into the early evening. Temps were in the mid to upper 30s yesterday but the rain turned into snow late in the afternoon. The ground was just too warm to let any of it stick and we wound up with just a trace of snow. Downtown Dallas nothing stuck because the ground was too warm. Up in Frisco, we had around a ½" on the grass.
