A cold front pushing across the Eastern and Central US will stall and slow down as it nears the Gulf Coast. During this period of slow movement, the Southern US will have the chance to see some snowflakes.
Portions of New Mexico and west and south Texas will experience snowflakes this Thursday into Thursday night. In fact, this snow may get as far south as Brownsville, TX. The last time this location experienced snow was on Christmas Eve in 2004!
Snowfall accumulations will be certainly be light. Most locations that experience snow will likely receive from a dusting on up to two inches. Some areas of southern New Mexico may pick up four inches, and some areas in west Texas could see as much as six to seven inches.
Looking ahead to Friday, the risk for some southern snow moves into the Southeast. The morning commute on Friday may turn out to be unusual, as snowflakes will begin to fall in the AM. The snow will possibly continue throughout the day in southern Mississippi, central Alabama, and northern Georgia. Overnight, portions of South Carolina and North Carolina may deal with snow as a coastal storm develops along the front. Again, the reason behind all of this is the slow-moving cold front. Precipitation will linger behind the front while cold air moves in from the north. This combination of the near-freezing temperatures and precipitation will cause snow.
Snow accumulations in the southeast will be very minimal (up to 1-2 inches on grassy surfaces), so don’t expect the scene from past winters of thousands of people trapped on the highway stuck in the snow—this will not happen! Temperatures will stay above freezing in the deep South, limiting the ability of snow to stick on the roads. Further north and east in the southern Appalachians, where the ground may be a bit colder, an inch or two at max will fall.
