Weather Underground Forecast for Monday,December 15,2014
A
cold front will shift across the central and eastern thirds of the
country on Monday, while a Pacific system will affect the West Coast.
A cold frontal boundary will extend across the Great Lakes, the upper Midwest, the Mississippi Valley and the southern Plains on Monday. During the morning, an area of low pressure along the northern tier of the frontal boundary will usher light to moderate snow showers across the Dakotas and the upper Mississippi Valley. Meanwhile, a potent low pressure system will move northeastward over the central Plains, the middle Mississippi Valley and the upper Midwest. As this system draws moisture from the Gulf of Mexico, heavy snow showers and freezing rain will impact the central and northern Plains, as well as the upper Mississippi Valley. In addition, showers and thunderstorms will develop ahead of the aforementioned cold front over the western Gulf Coast and the lower Mississippi Valley. Light showers will spread across the Tennessee Valley and the Ohio Valley during the late afternoon and evening. Weather conditions will remain relatively calm across the Eastern Seaboard as high pressure builds over the Mid-Atlantic.
A separate cold front will slide across the West Coast on Monday. Light to moderate rain will develop from western Washington to southwest California. High elevation snow showers can be expected over the Cascades, the Sierra Nevada and parts of the Great Basin.
