A low pressure system that has brought a great deal of snow to the northern Plains and Great Lakes was expected to continue to wind down on Sunday, though light snow was forecast continue to accumulate in the frigid air filtering in behind the storm.

Meanwhile, a coastal low pressure system moving up the East Coast was expected to bring heavy rain to New England. Most of the region was expected to receive snow from the storm, with snow in the forecast for Maine.

In the South, high pressure was expected to build eastward, keeping skies clear throughout the southeastern U.S. and for all but the beaches of the Gulf Coast.

A storm in the Gulf Coast was forecast to send a few showers ashore.

The same high pressure system was expected to also affect the Southwest, Rockies and High Plains, bringing clear skies and dry conditions.

West of the Rockies, a relatively dry storm system was expected to continue to slowly make its way ashore, eventually moving into the Northwest. High pressure in the region was forecast to slow the storm's approach in the region, pushing precipitation southward into California before Washington even begins to see cloud cover. By the end of the day, rain was in the forecast throughout the coast, although the showers were expected to be widely scattered away from the central California coast.

Temperatures in the Lower 48 states Saturday ranged from a low of -18 degrees at Belmont, Ariz., to a high of 73 degrees at West Kendall, Fla.
