Yes, Widespread
Last week's mix of storms, west and east winds, and high pressure has created a heterogeneous snowpack in the lowlands with diverse travel conditions. Subtle changes in aspect reflect sun's increasing intensity and multiple wind directions this week. Surface hoar buried above sun crust on any southerly tilt and on density change everywhere else.
Sunday's rain at BTL in this area will void much of this.
