A sprawling and dangerous winter storm will affect most of the central and eastern U.S. Tuesday, frozen precipitation will continue to develop across the nation’s mid-section and spread across the Midwest and Northeast. Significant accumulations of freezing rain can be expected from the Ozark Plateau into the northern Mid-Atlantic States, while heavy snow will fall from the central and southern Rockies into the Midwest and Northeast. Bitterly cold weather will trail the storm.
Locally, periods of snow, sleet, and freezing rain will occur Tuesday, then change over to all snow over the entire area by Wednesday as sharply colder air moves. Snowfall accumulations of over 12 inches are possible along and north of a Taylorville to Danville line. Ice accumulations up to three-quarters of inch are also possible south of a Taylorville to Danville line.
