A strong and deep low pressure system that has developed across the Central U.S. will continue tracking northeastward and up the Ohio River Valley. Winter storm warnings are in effect from the Mid-Mississippi River Valley to the Great Lakes as snowfall totals will range from another 2 to 6 inches in the Midwest, pushing storm totals from 12 to 17 inches of snow in some areas. An inch of freezing rain and sleet is anticipated across the Northeast and New England, thus, an ice storm warning has been issued for New Jersey, Massachusetts, Connecticut and southeastern New York. Blizzard conditions will also persist from the Midwest to New England as 25 to 35 mph winds are expected with gusts up to 40 and 50 mph. Many areas will see white out conditions. Extremely dangerous road and travel conditions are anticipated across most of New England and the Lower Great Lakes region. A cold front produced by this system extends southward, and will move from the Lower Mississippi River Valley to the Carolinas. This front is capable of producing some intense rainfall as it pulls in ample moisture from the Gulf of Mexico. Expect rainfall totals along this front to range from 1 to 2.50 inches.
Behind this system, extremely cold air will pour into the Northern Plains, Northern Rockies and Upper Midwest. As strong winds prevail, windchills will range from 20 to 30 degrees below zero across Minnesota, the Dakotas and the Central Plains. Expect wind ranging from 15 to 25 mph, with gusts up to 35 mph.
Temperatures in the Lower 48 states Tuesday ranged from a morning low of -42 degrees at Havre, Mont., to a high of 82 degrees at Plant City, Fla.
