Wasn't this whole subject discussed at length last year?

Possibly. However, last winter was so mild that I apparently never noticed
the phenomenon on my (then new to me) 496.

This winter -- the harshest in decades -- has reduced our flying to furtive
trips around the pattern whenever the storms let up. We've received over
20" of new snow in the last few days...and another deep freeze is predicted.
