Dendritic December?

The forecast for this afternoon promises dendrite formation:

Expect snow intensity to pick up this afternoon as developing coupled jet structure induces large scale ascent/stronger isentropic lift in 290-295k surface. Forecast soundings suggest temperatures in the upper level cloud layer around -13c which is supportive of 70 percent ice cystal initiation.This coupled with 700mb temperatures of -13c should be supportive of fairly good dendrite snow Crystal fall growth this afternoon and evening.

It's time we Minnesotans got to know our flakes.
