I have been watching the south-facing snow banks along the street, wondering when the snow would begin to melt back wherever dust and dirt catches the sun. Today was the first sign of it this year. I think it takes a certain combination of sun angle, sunny days, and air temperature, so the date varies. I have a picture of an advanced stage of the thaw from March 15th, three years ago, here.
