One computer forecast model shows abundant snow while the other shows a much weaker storm system Thursday through Saturday.

Snow and ice will return to the South this week. Maybe.

(CNN)If you can believe it -- MORE winter weather could impact the same spots later this week as what are getting hit Monday and this past weekend.

Like my five-year-old, you might still feel like you need to #BlameJudson for the lack of snow. He put the spoon under his pillow, threw ice cubes in the toilet, ran around the table singing "Let it snow, let it snow, let it snow" AND wore his pajamas inside out the night before. Even though we saw white flakes, there still wasn't enough snow on the ground to use the sled I bought him when he was two.
I am as disappointed as anyone that our snowless streak in Atlanta continues. But there is a chance -- if we get measurable snow later this week -- we will keep from breaking the record of going 1,477 days without snow. (We are currently sitting at 1,460 days Monday.)
Some computer forecast models are hinting at another winter system to hit parts of the South and make its way up the coast this weekend. This storm system, if you believe one model, will bring real snow to Atlanta, but also an icy mess to coastal towns like Savannah in Georgia and Charleston in South Carolina.
Not to mention, it could actually bring good accumulating snow to cities in the Northeast, like New York.
The problem is, there is less uncertainty in this storm system than this past weekend.
Last week, both global weather models showed the same overall weather pattern but disagreed on the details.
This week we can't even say we are sure something WILL happen.
"Ample forecast spread and continuity issues limits predictability of particular system threats days 4-7," the Weather Prediction Center said Monday morning in its forecast discussion.
What is certain is that a cold front will push through the Central US Wednesday and across the East through Thursday, leaving an Arctic blast of frigid air behind it.
Frigid below-average temperatures dive south and east Wednesday through Thursday.
Temperatures from the Plains to the East Coast could drop 20 to 30 degrees below normal.
Texas, for instance, will have many areas go from the 70s and 80s Tuesday to mid-30s and lower 40s on Thursday.
As frigid temperatures established across the East Thursday into Friday, a low pressure system is expected to form along the cold front and just off the Georgia coast. If it forms near the coast, it could filter in moisture from the Atlantic into the cold air, allowing for that winter precipitation to form in areas that you might not associate with ice or snow. Take Charleston, South Carolina, for instance.
"The thermal profiles of all of the medium range models indicate the potential for wintry precipitation across all or part of the forecast area at some point from late Thursday night through Saturday morning," the National Weather Service in
