A new winter storm is threatening to blanket portions of the South and Southeast in snow and ice through the end of the week.
High pressure over the Midwest will continue to send unseasonably cold air southward through the end of the week. At the same time, an area of low pressure will begin to develop over the western Gulf of Mexico today and Thursday and will send plenty warm, moist air northward.
The collision of these two air masses will result in moderate to heavy rainfall and thunderstorms along the Gulf coast, with snow and even some ice farther north starting on Thursday and continuing into early Saturday.
Winter Storm Warnings are in place across northeastern Texas, southeastern Oklahoma, and central and southern Arkansas, including Little Rock, Ark. and Dallas. Winter Storm Watches are currently in effect from northern Texas and southeastern Oklahoma eastward through northern Georgia, Tennessee, southern Kentucky, and far western North Carolina. This includes cities such as Memphis and Nashville, Tenn., Tupelo, Miss., Huntsville and Birmingham, Ala., and Atlanta.
A swath of 2 to 6 inches of snow is expected from Thursday afternoon through Saturday morning on the northern side of this storm. In addition, a small area of freezing rain and sleet will be possible from northeastern Texas to northern Georgia, where upwards of 0.05 inches of ice will be possible.
Meanwhile, moderate to locally heavy rainfall will occur on the warm side of this area of low pressure. Rainfall totals of 1 to 3 inches will be possible from southeastern Texas to southern Mississippi. This may lead to localized flooding in urban areas and in poor drainage areas. Remember, “Turn Around, Don’t Drown!” if you approach a flooded roadway. While a few embedded thunderstorms will also be possible on Friday, widespread severe weather is not anticipated at this time.
A piece of this storm system will combine with an arctic cold front that will move across the Upper Midwest and Great Lakes on Friday and through the Northeast on Saturday. Along and ahead of this front, light snow will develop across the Great Lakes, Ohio Valley, and Mid-Atlantic on Friday into Saturday. Here, snow accumulations will generally be under 2 inches, but localized snow accumulations of 3 or 4 inches will be possible, especially over higher elevations.
