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 categories or to add to the categories already present. That is why some categories have scripts not realted to the category title. Best advice is to check total posts, that will let you know something, could be anything has been added...and it probably is not related to the title of the category. I will try to limit each category in the future, to 5 posts per. 8-)

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, theoretically :neutral:

Another version of pot. precip. place.

This one uses 850mb convergence:

EDITED :oops: :oops: :oops: Fixed line that had SSUM...should have been sdif!!!!!

Thought I had included this earlier, may not have done so. Temp contour (fill and line).

Added diagonal fill for convergence to original, and added output of relative humidity at 925 mb X ave mixr. May add an Ave rel. hum. X ave. mixr. later.
