My understanding is that the 540 line is where freezing temps start.

The 540 line is TYPICALLY the rain/snow line... but not always.

The 540 line is the southernmost blue one.

That value only works for the areas east of the Rockies-for the West Coast it takes a far lower value for sealevel to low level snowfall.
