Weather Underground Forecast for Monday, February 16, 2015

An area of low pressure will slide across the Deep South on Monday, while an arctic high pressure system will settle in over the Northeast.

A low pressure system is forecast to move eastward over the southern Plains, the lower Mississippi Valley and the Deep South. This system will draw moisture from the Gulf of Mexico, bringing chances of moderate to heavy precipitation to the southern tier of the country. An arctic air mass will interact with this low pressure system. As warm, moist air from the Gulf of Mexico overruns the arctic air, a mixture of freezing rain and snow will impact the southern and central Plains, the middle and lower Mississippi Valley, the Deep South, the Tennessee Valley, the Ohio Valley and the Mid-Atlantic. Snow showers are expected to wind down over the upper Midwest and the Northeast, although a frigid air mass will settle in over the region. Blustery conditions are expected across the northern tier of the country. Wind chill warnings are in place for a handful of states, including Maryland, Pennsylvania, New York, Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire and Maine.

Meanwhile, a cold front extending across the Intermountain West will generate moderate to heavy snow showers across the Rocky Mountains. Winter weather advisories are in place for Colorado, Wyoming and southern Montana.

A ridge of high pressure will continue to influence a dry weather pattern over the western third of the country. Temperatures will range between the 70s and 80s across the Desert Southwest on Monday.

Temperatures in the Lower 48 states Sunday have ranged from a morning low of -27 degrees at Land O, Wis. to a high of 80 degrees at Miramar MCAS, Calif.
