The National Weather Service is predicting possible snowfall in South Mississippi on Thursday and into Friday morning, furthering the prediction that the weather would change if the Saints won the Super Bowl.
A surface low is expected to develop in the Gulf of Mexico on Thursday. As moisture increases across the area late Thursday morning and into the afternoon hours, a mix of sleet and snow will begin to fall across South Mississippi and southeast Louisiana, mainly north of Interstate 12.
A few areas as far south as Donaldsonville, La., and LaPlace, La., may see sleet mixed with rain through Thursday afternoon. As night rolls around the surface low is expected to track across the northern Gulf of Mexico near the Louisiana Coast.
A changeover to all snow should occur over South Mississippi. Accumulations of 2 to 4 inches will be possible overnight. The snow may be heavy at times, which could result in isolated amounts higher than 4 inches.

Points south of this, such as the Baton Rouge metro area and east along Interstate 12 will be in a mix of rain and snow. Accumulations will be less in these areas at 1 to 3 inches.
By Friday morning, the surface low should be tracking east of the area and snow should end by Friday afternoon.
The National Weather Service does caution that because the forecast is a couple of days off, the forecast is uncertain. If the low tracks farther away from the Coast toward the central Gulf, little if any accumulations would occur.
