Another rain-heavy atmospheric river is lining up to hit Northern California through much of next week.

The first wave is expected to hit Sunday night, followed by a warmer storm midweek.

Snow levels for that second round will likely be above the seven thousand foot level.

Meteorologist Jim Mathews with the National Weather Service in Sacramento says flooding from rapid snow melt is not a concern at this point.

There will be some melting occurring at the lower elevation," says Mathews. "But, actually the snowpack, as thick as it is, will act a sponge and absorb most of the water."

Matthews says much of the mid-week system is also expected to push into far northern California and Oregon.

Snow levels will then drop for yet another system expected to arrive late in the week.
