The winter storm was expected to linger over the East Coast and bring another messy day to New England and the Northeast. A low pressure system was forecast to keep pushing northward up the East Coast and pulling cool and moist conditions into the region.

A winter weather advisory was issued over the region, with 3 inches to 5 inches of new snowfall expected over much of New England. Further north, a blizzard warning was in effect for Massachusetts as 6 inches to 10 inches of snow was anticipated with winds gusting up to 30 mph.

The conditions could mean dangerous road and travel conditions over most of the eastern U.S.

To the west and south of the storm system, dry and cool conditions were expected as high pressure started to build in from the Plains. A few scattered clouds were forecast over the Central and Southern U.S., with temperatures in the South expected to remain in the 50s, while the Midwest was forecast to see highs near 30.

A weak low pressure system tracking through the Northern Plains and Upper Midwest could allow for a few scattered flurries on Sunday.

More active weather was anticipated in the West, as a low pressure system moved onshore from the Pacific Ocean. This system could mean widespread scattered precipitation over most of the Pacific Northwest. Less than a quarter of an inch of rain was expected over most areas, while light snow with accumulation of up to 3 inches was expected over the higher elevations. The rest of the West was forecast to see cool conditions with overnight lows dropping below freezing in some areas.

Temperatures in the Lower 48 states on Saturday ranged from a low of -20 degrees at Berlin, N.H., to a high of 82 degrees at San Diego.
