Weather Underground Forecast for Saturday,January 11,2014

An active weather system will push across the eastern third of the country on Saturday, while a cold frontal boundary will move over the Northwest.

An extensive cold frontal boundary will stretch from southern Texas to the central Great Lakes. As a low pressure system interacts with a warm, muggy air mass surging northward from the Gulf of Mexico, conditions will be favorable for thunderstorms development across the southeast and into the Mid-Atlantic. Severe thunderstorms will be possible from Florida to the Mid-Atlantic Coast, while showers and weaker thunderstorms will develop further inland. Along the northern portion of the frontal boundary, a low pressure system will trigger snow showers across the Great Lakes and into the Ohio Valley, while freezing rain will be possible across northern New England.

The majority of the central U.S. will stay clear of precipitation, although light rain and snow will fall in parts of the northern Plains.

Meanwhile, a separate cold front will begin to trek across the Northwest on Saturday, providing rainy conditions to northern California, Oregon and Washington. Heavy snow can be expected across the Cascades and northern Rockies, while lighter snow will push across the northern Sierra Nevadas and central Rockies. The desert Southwest will avoid precipitation on Saturday as high pressure prolongs a dry spell across the region.
