Never seen a run put the DGZ at literally 300 feet above the ground even if only a tick is fully saturated. Still interesting regardless.

TBH, I'm more disappointed in this Tuesday's system more then anything. 850s just a few degrees off from a novelty inch or two.
 
What does this mean?
Usually the dendritic growth zone is found way higher in the atmosphere. When it snows, that’s the region where it comes from. You’re usually talking the layer that is -10c or below in your sounding. That’s normally found way up, roughly 8k feet. In this case, it’s just off the ground comparatively. That’s how it snows so easily in places like Michigan. You don’t need a whole lot of moisture if your growth zone is close to the ground.
 
I can this this path for the low. For whatever reason the models want to create a second jet in IL from the SSW phase. Not doubting it. I just think there could be a scenario where the low travels East of the mountains based on the PVA jet locations. In this run, there was less interaction with the SSW which meant a further East low. Also, what's picking up the SSW currently is aircraft traveling from CONUS to HI, not soundings yet. 1671318744317.png

Thank you so much
