We had the most extreme weather a week ago.  First was the snow, more than I can remember seeing here.  It came down fast and just kept on coming, over a foot.  Then while the snow was on the ground we had a 12degree low at night, following by an 18degree low.  Meanwhile daytime temps never got above freezing and all this occured after mild, spring like weather had encouraged bud growth.  It will be interesting to see what the ultimate result will be.
