Another reason I'd be surprised if it goes to all sleet even once mixing starts, I'm sure its possible but can't remember too many times at least near the coast when it's been in the teens and pure sustained sleet. Maybe valentines day 2007 but even that was probably in the 20s?

I lived through that VD 2007 storm in central PA and it was dumping sleet at maybe 10-12 degrees. What happens at 750 or 800mb is irrrelevant to the surface. If there's strong southerly flow at those levels because of a primary and 700/850 lows in a bad place, those levels will warm up and it will sleet.

Yea again I'm saying near the coast it seems a very rare phenomenon to get both sustained sleet and temps below 20, usually either the upper levels aren't as warm as modeled or the surface warms more, always some exceptions. Inland is a different story.

Holy cow, for those of us on here who are not mets primarily interested in the science, to be on your PC or phone obsessing over the sleet line when the thing you've spent a week tracking - heavy snow - is happening outside the window, is bizarre.  Enjoy the snow for crying out loud.  It was never going to snow forever.

I think part of the fun is nowcasting vs. what was modeled and that includes tracking the sleet line! Still a great storm regardless ad it’s not often we get such cold, dry high ratio snows.

I had 5 inches of sleet in 2007 with temps in the upper teens to low 20s here in Brooklyn.
