Weather Underground Forecast for Saturday,January 3,2015
A
low pressure system will move across the Gulf Coast and the Mississippi
Valley on Saturday, while a separate system will develop over the
northern Plains.
A vigorous low pressure system will shift north northeastward over the western Gulf Coast and the middle Mississippi Valley. This system will draw moisture from the Gulf of Mexico, fueling rain and thunderstorms across the Gulf Coast, the lower Mississippi Valley, the Deep South, the Tennessee Valley, the Ohio Valley and the southern Mid-Atlantic. There will be a chance of severe thunderstorms over southeast Louisiana, southern Mississippi and southwest Alabama. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Heavy rain associated with these thunderstorms will bring a threat of flash flooding to northeast Louisiana, northwest Mississippi, eastern Arkansas, northern Alabama, northwest Georgia, Tennessee and southeast Kentucky. A swath of mixed precipitation will impact the southern Plains, the middle Mississippi Valley, the southern Great Lakes and the interior Mid-Atlantic. In addition, moderate to heavy snow showers will affect the central Plains, the upper Midwest, the Great Lakes and the Northeast.
A separate system will dip south southeastward over the northern Plains. Light to moderate snow showers will be possible across the central and northern Rockies, as well as the northern Plains. Just to the west, an onshore flow from the Pacific will bring late evening rain to Washington. High elevation snow showers will be possible over the Cascades.
A ridge of high pressure over the eastern Pacific will keep weather conditions calm across the Southwest, the Great Basin and the southern Rockies on Saturday.
