Snow is blanketing northern Texas to northern Ohio while an icy mess is unfolding from northeastern Texas through the Tennessee Valley. The most significant icing is occurring in Arkansas and eastern Oklahoma. Click here for a live look at the winter storm unfolding across the Mid-South.
Winter Storm Warnings and Winter Weather Advisories stretch from Texas Rio Grande Valley to western Massachusetts. Dallas, Oklahoma City, St. Louis, Indianapolis, most of Ohio, Pittsburgh and Binghamton, N.Y., are all included. Ice Storm Warnings continue from southeastern Oklahoma into western Tennessee, including Memphis, Tenn., and Little Rock, Ark.
The heaviest snow will fall from southern Indiana into northern Pennsylvania where 6 to 10 inches will blanket the ground. Surrounding this zone, totals will be less than 6 inches from northern Arkansas into southern New York.
Ice will be most problematic from central Arkansas into western Tennessee where up to one-half inch will cause slippery roads and power outages. If you must travel, allow plenty of extra time and distance between you and the next motorist, that way you arrive at your travel destination safely.
So far, the greatest ice totals have occurred in the Mid-South and Southern Plains. A few of the highest totals include Johnson, Ark., and Muskogee, Okla., with 3 inches of sleet, and Greenwood, Ark., measuring 1.25 inches of freezing rain.
The bull`s eye for snow is southern Illinois with 10 inches reported at Mount Vernon. Most snow totals range from 3 to 8 inches from the Mid-South to the Midwest. So far, the wintry weather has not caused any flight delays in the Central U.S.
The front will slowly ease to the East Coast through early Saturday. Snow and ice will end in the nation`s midsection with rain changing to freezing rain, sleet and snow along and north of Interstate 80 in Pennsylvania on Saturday with a few inches of wet snow and up to a tenth of an inch of ice expected.
The problems won`t end Saturday. An Arctic high pressure will glide in behind the front Saturday while low pressure develops on the front`s southern flank across the Central Gulf Coast. The low will track north into the Ohio Valley Sunday afternoon into early Monday.
Ahead of the storm`s center, snow will develop from south to north from the Mid-Atlantic into New England but warmer air moving in aloft will change the precipitation to a dangerous mix of sleet and freezing rain from the Appalachian Ridge to the Interstate 95 corridor.
While snow accumulations will be less than 4 inches, ice will cause major problems in the Mid-Atlantic late Sunday into early Monday. Freezing rain could accumulate more than one-quarter inch along Interstate 81 from Roanoke, Va., to Harrisburg, Pa. One-tenth of an inch of ice will coat secondary roads, sidewalks and parking lots in the major Mid-Atlantic metropolitan areas.
Already, Winter Storm Watches are posted from northern North Carolina into western Maryland. These watches will likely expand north along Interstate 81 later into Pennsylvania, with winter-related alerts also possible along the populated Interstate 95-corridor in the Mid-Atlantic.
The storm will exit early Tuesday, with cold air pouring in behind the departing cold front. This could lead to refreezing of melted snow and ice.
