Here comes the snow! Just what we plein air painters have been waiting for. 

After you get all your groceries put away and make plans for the animals and other family members, I hope you'll have a chance to paint--try a view from your windows!  I still consider this plein air, because all the conditions are the met (painting the outdoors while there, in real time, dealing with the changing light)--except you're warm and comfortable. AND as a bonus, with snow the light does not change that much.
