The nation's weather

A powerful Pacific storm will pound California and Nevada with heavy rain and high elevation snow. Winter storm warnings are in effect for the Sierra Nevadas of California with up to 2 feet of new snow possible above 7,000 feet. Some lower elevations in California could experience more than an inch of rain, prompting flooding concerns.

High wind warnings are in effect for almost all of California and Nevada as southerly winds will gust up to 75 mph in the lower elevations and up to 100 mph along the ridges of the Sierra Nevadas. The intensity of the wind may potentially knock out power to some populated areas.

Meanwhile, another storm will move into the upper Midwest, spreading rain. The rain will make its way into the Mississippi Valley watershed, adding to an already potentially record-breaking flood season. Flood watches and warnings are already in effect for the Mississippi River.

Temperatures in the Northeast will rise into the 30s and 40s, while the Southeast will see readings in the 70s and 80s. The Southern plains will see temperatures in the 80s and some 90s, while the Northwest will see 40s and 50s. Higher elevations will only rise into the 20s and 30s in the West. Temperatures in the lower 48 states on Saturday have ranged from a morning low of 6 degrees at Crane Lake, Minn., to a high of 89 degrees at Augusta Bush, Ga.
