Rain fell across the eastern half of the nation Sunday and started turning into a major snowstorm for the Northeast. Another storm moved onto the West Coast, threatening heavy snow in the mountains.

Showers and some locally heavy rain stretched from the Ohio Valley and along the length of the East Coast.

The rain turned to snow in parts of Pennsylvania and New York as a nor'easter developing along the coast dragged in cold air from the north. Winter storm watches were in effect from northern Virginia to Maine as the storm was expected to dump one to two feet of snow over a two-day period.

Farther south, a line of thunderstorms stretched across Florida and along the coasts of Georgia and the Carolinas, moving out to sea during the afternoon.

Rainfall in parts of Florida was estimated at around 2 inches.

Along the West Coast, rain fell across much of California and into Oregon, with up to three-quarters of an inch of rain in parts of California. Light rain also started moving into western Nevada.

Winter storm warnings were posted for California's Sierra Nevada, with one to two feet of snow possible at higher elevations.

Sunday's temperatures around the Lower 48 states ranged from a midday reading of 88 at Fort Lauderdale, Fla., to a morning low of 24 below zero at Presque Isle, Maine. The lowest wind chill was 32 below zero at Jackson, Wyo.
