Another snow script: fill below 0 wet bulb at 700 850 925 and surface levels. areas with all 4 fill types have all levels below 0 wet bulb temp. Theoretically if precip occurs there is possibiity of "wet bulbing" and any snow that occurs will cool "warmer" levels to the point that no melting occurs ...

SPC has a combination of PW and Surf Conv on their site. It is listed as potential precipitation placement. I have run this and seems to work pretty well. This script shows pw from a previous script and overlays surf conv lines.
I am also trying to figure out if it is better to add scripts to new ...

I have been playing with this script for about a month now, Have no idea if this is accurate. IFF the term is (differential vorticity) advection this should be close...if it is differential (vorticity advection) then it is worthless. What I can find online this shows areas where Cap could be eroded ...
