The nation's weather

[March 07, 2011] (AP) Much of the Eastern Seaboard will start seeing drier weather conditions Monday as the storm system over the area exits.

The cold front extending from the Mid-Atlantic through the Southeast will move into the western Atlantic as associated low pressure climbs northeastward up the New England coast. Ample moisture over the area will combine with this low pressure system to fuel more light to moderate rain with periods of heavy rainfall and thunderstorms in the Northeast and New England areas.

Mild temperatures and significant rainfall may promote rapid snow melt with sharp rises on area rivers and streams. Thus, expect areas from southern New England through the central Appalachians to remain under various flood watches and warnings into Monday morning.

In addition to rain, bands of snow showers and heavy, wet snow will develop from Maine through the lower Great Lakes. The interior of Maine will see the worst of these conditions with snow mixed with sleet and freezing rain at times. Snow and sleet accumulations in the area from Sunday afternoon through Monday afternoon are expected to reach between 14 to 20 inches. This area may also see up to a quarter-inch of ice accumulations.

Elsewhere in the East, waves of energy in the upper Midwest will bring light to moderate snowfall to the upper Mississippi Valley and light rain to the mid-Mississippi Valley. A more significant snow event may occur in the upper Mississippi Valley on Tuesday.

In the West, a developing trough of low pressure will fuel more low-elevation rain and high-elevation snow in northern and central California and the southern Pacific Northwest. Meanwhile, a Pacific cold front will move through the Great Basin with rain, snow and strong winds. Snow is expected to be significant over parts of northern and central Nevada. Heavy mountain snow is also expected across much of Utah, with rain changing over to snow across the western and central valleys.

Temperatures in the Lower 48 states Sunday ranged from a morning low of minus 11 degrees at Grayling, Mich., to a high of 84 degrees at Marathon, Fla.
