<p style=”text-align: left;”>Off topic, but watching snowdrifts form on my roof for +34 winters, this last >7″ blast dump left me wondering…hmm, I didn’t make the connection earlier….My roof ridge line is like a wing in stall condition, vortices all over the leeward side. A north snowblow over e-w gable ridge gets snow trapped on south. homebuilders call it “architectural shadow”, I looked it up. My low-pitch roof angle turns out , sadly, to be the perfect stall AOA!</p>
