The trough of low pressure over the central Plains will drop southeastward throughout the day, supporting a wave of low pressure that will trek eastward into the lower Ohio Valley with light to moderate snow showers. The trough will also support the development of another low pressure system along a cold front near the Western Gulf Coast. Flow associated with this system will enhance moisture along the central and western Gulf Coasts, allowing for showers, periods of heavy rainfall and chances of thunderstorms to develop primarily along the coast of Texas. In addition to active weather, warm moist flow will allow temperatures in the Southeast to warm back to near normal values.

To the north, an Alberta clipper system will bring snow to the Great Lakes on Monday. While light accumulations are generally expected across the region, intense lake-effect snow may produce heavier accumulations in western Mackinac County, Michigan. Temperatures in the Midwest and especially the Northeast will remain bitter cold Monday. Daytime highs in these regions are expected to drop to about 10 to 30 degrees below average.

Finally in the West, high pressure will keep much of the region under fair and dry weather conditions with near to above normal daytime highs. Disturbances in the eastern Pacific will keep chances of precipitation over the Pacific Northwest.

Temperatures in the Lower 48 states Sunday ranged from a morning low of minus 36 degrees at International Falls, Minn., to a high of 79 degrees at North Island, Calif.
