I’m intrigued by the curl up by the RGEM. Seems to be driven by the intensity of the s/w. Euro is in that camp with intensity. Sort of leaning in that direction with it being more intense.
I was going to post during the 12z runs and never did for 18z ones, but as Scott alluded to a little while ago, there does look to be some convective nature to this that may bring some intense banding and thunder snow potential.
