A major storm system was forecast to continue to bring winter weather to the northern Plains and Great Lakes regions Saturday. The broad low pressure system was expected to encompass an area from the Rockies to New England and the Mid-Atlantic.
A second storm was forecast to increase precipitation along the East Coast as it developed off the Carolinas.
Temperatures at the coast were expected to be warm enough that snow would be kept at bay Saturday. But inland, especially throughout the Midwest and northern Plains, temperatures were expected to be cold enough that any precipitation would be in the form of snow.
Southeasterly winds in the Great Lakes region are expected to allow warm air to flow north and keep most of the region from receiving much snow.
The Southwest and southern Plains were forecast to be cool but dry as northerly winds pushed Canadian air southward. Overnight lows were expected drop below zero all the way south to the northern reaches of the Gulf Coast states.
West of the Rockies, clouds were forecast to begin to increase across the Pacific Coast as a frontal storm moved closer to shore. By nightfall, rain was expected in Northern California, with precipitation moving inland overnight. Clouds were in the forecast for the Northwest, but precipitation should hold off until Sunday morning.
Temperatures in the Lower 48 states Friday ranged from a low of -24 degrees at Jordan, Mont., to a high of 83 degrees at Vero Beach, Fla.
