Another massive winter storm is forecast to pummel the southern and eastern U.S., with impacts from Texas to the Carolinas.

On Sunday, there’s a chance of snow, but current forecasts indicate it could be light, the weather service said. “Even if it develops, the system will be rather weak and progressive, so snowfall totals and resulting impacts appear minor,” the weather service said in its Thursday morning forecast discussion.

Twenty states, from Texas to Delaware, were on alert Friday for snow and ice as the storm continued to move across the South.

Brutal cold will open the door for a winter storm to take a somewhat unusual track through the South and create treacherous conditions.

Snowfall totals on Thursday are expected to be light. The weekend forecast for a more serious winter storm remains uncertain.

NWS reports confidence that a winter storm will bring precipitation to SC Lowcountry next week, but not yet saying snow. The Weather Channel says there will be.

More snow could be on the way.

After a blast of arctic air settles in this weekend, a storm system will track eastward across the South, bringing the potential for snow and ice. The details of who will see wintry precipitation and how much are still uncertain,
