There was a truck with snow on it in my school parking lot

I would advise to keep an eye on ICON and Herpes for the wind event. they both nailed previous wind events over here this winter

Grapefruit size hail reported with that cell.

FWIW (not much) the 18z GFS is a few notches South with the Thursday night system. Heaviest precip is around Olympia instead of Seattle. Looks more like the GEM.

This Pontiac cell has big trouble written all over it. Just has the look, and it should be riding near the warm front for a substantial amount of time as it has started to take a bit of a right turn.
