The Northeast was expected to see another day of scattered snowfall on Monday, while precipitation was forecast to return to the Pacific Northwest.

A low pressure system lingering off the Northeast and New England shores was expected to continue bringing cool conditions to the region. The system was expected to pick up moisture from the Great Lakes and Atlantic Ocean, which could produce light and scattered snowfall over the extreme Northeast. Lake-effect snow was expected to continue over the eastern shores of the eastern Great Lakes.

Between 4 inches and 8 inches of thick snow was expected to fall near the Great Lakes, while 1 inch to 3 inches was forecast over the rest of the Northeast. Blustery conditions with wind gusts of up to 20 mph were expected to persist as the low pressure system continued moving east.

In the West, a low pressure system was forecast to advance over the Pacific Northwest. The system was expected to obtain abundant moisture from the Pacific Ocean and bring scattered showers over Oregon and Washington, and snow at higher elevations of the Cascades. Highs were expected to return to the 50s over most of the West Coast.

Between the two systems, a large high pressure system was forecast to cover the Central U.S. from the Rockies to the Mississippi Valley. It was expected to pull cool air in from the North and allow for plenty of sunshine. Highs in the Northern Plains could reach near 10 degrees, while the Southern Plains were expected to remain in the mid-40s. Overnight lows could drop below freezing in the South and below zero in the North.

On Sunday, temperatures in the Lower 48 states ranged from a low of -36 degrees at Crane Lake, Minn., to a high of 81 degrees at North Island, Calif.
