FFC's current take on this system. They think we could see more than just the mountains getting flurries. Seems to go with the Euro's idea.
With surface low basically traversing the northern sections of the
forecast area, first inclinations would be that instability may be
hard to come by. But with such a dynamic system, it appears strong
diffluence aloft may aid in the development of elevated convective
elements north and surface based to the south. 50 to 60 knot low
level jet could be enough to allow for some localized strong to
severe storms as well.
On the back side of the system, much colder air will stream into
the area. Column max temperature profile indicates all temps
going below 0C quite quickly as wrap around moisture moves in. For
now, will introduce a mix of rain/snow for the higher elevations
but this may need expansion with subsequent runs should model
trends continue.
