[gembud] snow squall warnings in gpmap

Hi gembuds,

After we had one pass through this morning, I was trying to figure out how to 
get NWS snow squall warnings to show up using gpmap – I see that the 
functionality was added to GEMPAK a few versions ago but I don't see 
documentation for how to add them to the maps.  Is it just a modification to 
the WARN settings, etc., and if so, what needs to be added?

Thanks!

Russ
