Weather Underground Forecast for Monday,December 29,2014

A cold front will stall over the Southeast on Monday, while a separate cold front will extend from the Northwest to the central Plains.

A cold front will stretch across the eastern Gulf Coast, the Southeast and the southern Mid-Atlantic. This system will interact with moisture from the Gulf of Mexico, fueling rain and thunderstorms across the eastern Gulf Coast and the Southeast. A mixture of rain and snow will create messy road conditions over the interior Mid-Atlantic. Scattered snow showers will be possible over the Great Lakes, while conditions are expected to clear up over the Northeast.

Meanwhile, an arctic high pressure system will push bitter cold air across the Intermountain West, the northern Plains and the upper Midwest. As this cold air sinks southward over the Rockies, widespread snow showers will develop across the region. In addition, an onshore flow from the Pacific will bring coastal rain to northern California, Oregon and southwest Washington. Snow levels are expected to drop to roughly 3,000 feet across the Olympic Range, the Oregon Coast Range, the Cascades, the Wasatch and the northern Sierra Nevada. High pressure will keep conditions relatively dry across the Southwest, the southern Rockies and the southern Plains. Temperatures are forecast to range between the 50s and 60s across the Desert Southwest on Monday.
