One Maryland farmer I spoke with this past weekend voiced concern about this phenomenon. Snow on the ground serves several purposes - 1) it insulates the ground for any overwintering crops; 2) it protects the soil from dessication and degradation, keeping moisture and topsoil where it is; and 3) it allows for the water to seep into the soil and recharge groundwater, rather than skipping town in a hurry.
So while you may be enjoying a bit of 'good' weather, consider this - will new buds still arrive in the spring? Will we face a serious drought from lack of winter snow? How will the crops fare? Where are we all going to get our skiing in????
