Nice reminder that it's the vertical circulation induced by frontogenesis that produces heavy snow, not the 2-D frontogenesis itself.

The lifting associated with that circulation may or may not actually line up spatially w/the FGEN max, and will produce flakes through a layer. https://t.co/pd85VozB9U
