I really need to read up more on plumes and their accuracy.
The GEFS plumes paints about a 5in snow storm around KGSP. I still need to do research, but ensembles and plumes are painting a different story then the operation models are suggesting.
I am assuming that is why it’s important not to just go by the GFS or the EURO or any OP model alone, but use its members and ensembles.
