Weather Underground Forecast for Sunday, March 16, 2014
A cold frontal boundary will stretch from the southern Plains to the Mid-Atlantic on Sunday, while a separate frontal boundary will approach the Pacific Northwest.
Another round of cold air will move across the central and eastern thirds of the country on Sunday as a cold frontal boundary extends from the southern Plains to the Mid-Atlantic. This cold front will interact with an abundance of warm, muggy air from the Gulf of Mexico to produce widespread showers and thunderstorms. Thunderstorms will be possible from central Texas to the Carolinas, while parts of central Gulf Coast will have a chance of severe thunderstorms. As cold air digs southward over the Midwest and eastern states, a mixture of sleet and snow showers will develop across the middle Mississippi Valley to southern New England. Pockets of heavy snow showers are forecast to impact a handful of states, including Missouri, Illinois, Kentucky, Ohio, West Virginia, Virginia, Maryland, Pennsylvania and Delaware.
Meanwhile, a separate cold frontal boundary will begin to move across the Pacific Northwest on Sunday. This system will usher rainy weather over Washington, Idaho, Oregon and parts of northern California, while moderate to heavy snow showers will push across the Cascades. The Southwest will stay warm and dry on Sunday due to high pressure along the eastern Pacific. Temperatures will range between the 80s and 90s across the Desert Southwest. .
Temperatures in the Lower 48 states Saturday have ranged from a morning low of -14 degrees at Crane Lake, Minn. to a high of 84 degrees at Thermal, Calif.
