Weather Underground Forecast for Tuesday,January 13,2015

A cold front will move across the East Coast on Tuesday, while an area of low pressure will inch across the Intermountain West.

An extensive cold front will shift eastward over the western Atlantic. Snow showers will linger over parts of southern New England and the northern Mid-Atlantic during Tuesday morning. The southern end of the frontal boundary will move much slower across the eastern Gulf Coast, the Southeast and the southern Mid-Atlantic. A wave of low pressure is expected to develop along the tail end of the cold front. As this system taps into moisture from the Atlantic Ocean, a mixture of rain, freezing rain and snow will develop across West Virginia, Virginia, eastern Tennessee, North Carolina and northern South Carolina. Cold rain will affect the Southeast, while showers and thunderstorms will fire up over southern Florida.

Meanwhile, an arctic high pressure system will sink southeastward over the upper Midwest and the Great Lakes. Temperatures will struggle to climb above the single digits from the northern Plains to New England. Additionally, scattered snow showers will be possible over the upper Midwest.

A trough of low pressure will progress slowly eastward over the Intermountain West. This system will usher light to moderate snow showers across the central and southern Rockies. A mixture of rain and snow is expected across the lower elevations of New Mexico. By the late afternoon and evening, light snow showers will spread across the southern high Plains. Just to the west, a ridge of high pressure over the eastern Pacific will keep weather conditions calm from the Pacific Northwest to the Southwest.
