A storm system pressing across northern Mexico will spread rain and snow over the southern Plains today. This storm will drench the South Central states through the middle of the week, before targeting the Eastern Seaboard just in time for the new year.
Snow will overtake New Mexico and western Texas today and advance across Oklahoma tonight. Accumulations of 1 to 3 inches can be expected, with as much as half of a foot piling up in parts of western Texas.
A wintry mix of rain and snow could lead to slick roads for a time along a swath from Junction to Dallas, Texas, by this afternoon, reaching towards Little Rock, Ark., overnight tonight.
Meanwhile, soaking rain will press across cities and towns farther south and east from southern and coastal Texas into the lower Mississippi Valley today through Wednesday. By Thursday, the wet weather will engulf the Southeast.
During the next few days, the heaviest rain will target the Gulf Coast. This could renew flooding problems, since waterways in this area have already been swollen by record-shattering rainfall of late.
As the storm journeys northward along the Eastern Seaboard on New Year's Eve into the weekend, advancing cold air colliding with lingering moisture will lead to accumulating snow in the southern Appalachians. As the storm departs, the new year will start out with unusually cold temperatures across the South.
