Weather Underground Forecast for Saturday, January 31, 2015
A trough of low pressure will slide across the Southwest and the southern Plains on Saturday, while a separate system will impact the Northeast.
An area of low pressure will move northeastward over the coast of New England. This system will strengthen over the western Atlantic, bringing moderate to heavy snow showers to eastern New England. The heaviest snow will develop across eastern Maine, where accumulations will approach one foot. Snow accumulations will range between 6.0 to 12.0 inches from eastern Massachusetts to eastern New Hampshire. In addition, scattered snow showers will linger over the northern Mid-Atlantic. The remainder of the Eastern Seaboard will experience calm weather conditions on Saturday.
Meanwhile, a trough of low pressure will slide across northern Mexico, the Southwest and the southern Plains. This system will draw moisture from the eastern Pacific, initiating widespread rain and snow across the Southwest, the Four Corners and the southern Plains. The heaviest precipitation will focus over Arizona and New Mexico. During the afternoon and evening, snow showers will spread eastward over the central and northern Plains, as well as the Midwest. Light to moderate rain is also expected across the southern Plains and the lower Mississippi Valley. A ridge of high pressure over the eastern Pacific will keep conditions relatively clear over northern California and the Pacific Northwest on Saturday.
