Looking at the text output and TT are in the 50s for TAN.  Nice signal for some T-snow.

 

The difference here is that it's actually very hard to get thundersnow in this set up. If you look at the soundings, it's not a MAUL type sounding where you have elevated CAPE...it's sort of unstable from the ground up...but lacks good elevated CAPE. You can get 4"/hr rates...but I can't recall an inv trough setup that had TSSN.

It would have to be extremely intense

If we could get that, I would be fine resorting to make thunder noises with my iPhone. :lol:

I think the March 1992 event had TSSN in E MA. But yeah, you like to see soem CAPE and also like to see the lift deeper than in a norlun event...the lift can be intense, but its often relatively shallow in these setups. Though the NAM looks a bit more impressive in this one....it does have a bit of a MAUL on the ORH counding around 69-71 hours.

Here is the TAN sounding
