Snow and sleet will fall in parts of the Carolinas on Sunday morning, but forecasters say they think Rock Hill-area residents will see only rain from the wintry system.
It could be a close call, though, as National Weather Service meteorologists say they’re dealing with a tricky forecast.
Sunday’s system will come on the heels of another outbreak of cold weather that will hold afternoon high temperatures across the Rock Hill area to the 40s on Friday and Saturday.
National Weather Service meteorologist Scott Krentz said a weak low pressure system is expected to develop along a cold front that will cross the Carolinas on Sunday. Precipitation is predicted to begin as snow in the early-morning hours Sunday across the North Carolina mountains and extreme northwest South Carolina.

Some warmer air will be dragged into the system at the mid levels of the atmosphere, Krentz said, allowing the snow to change to sleet in some places.
The tricky part of the forecast is determining how cold temperatures will get overnight Saturday. For now, the Weather Service expects Sunday morning lows will be around 34 degrees. That means the precipitation will fall as rain in the Rock Hill area.
But, Krentz added, “any change in minimum temperatures (Sunday morning) will change precipitation types.”
For now, the Weather Service is expecting a few inches of snow in the North Carolina mountains and a lighter amount of snow and sleet in northwest South Carolina and the North Carolina foothills.
Either way, Krentz said the snow won’t last long Sunday. Rain is expected to continue throughout the day, with afternoon temperatures reaching the mid 40s. And lows Sunday night are forecast to remain above freezing.
“So any accumulations will melt, limiting the impact concerns,” Krentz said.
