Thanks to Tom Abell who alerted me to these
experimental NWS WPC graphics, I was finally able to assemble a script for the Saratoga template in order to
selectively display them. They are published by select WFO's, and I think the list is comprehensive with all of the non-contributors weeded out.
There are several winter weather variables whose maps contribute to the final Winter Storm Severity Index. These are selectable per WFO via a second drop-down.
The script is available on
my scripts page. Be aware that there's a link to the StandAlone version in the script, so it should be uploaded as well.
