The Lower 48 is in the grips of yet another cold snap as weather outlets forecast winter storms for many in the deep south.

Winter storms are being called for from Mississippi to South Carolina and a state of emergency has been called in South Carolina as well as Louisiana. Louisiana Governor Bobby Jindal is warning that state’s residents to remain indoors, and schools are closing and road crews are preparing for the predicted ice storms.

This cold snap moving into the south has been plaguing the Northern Plains and the northeast, residents there are still dealing with temperatures that has dropped to wind chills of 35-50 degrees below zero in recent days. The state of Minnesota is still faced with plummeting temperatures even as they struggle with shortages of natural gas following the Canadian natural gas pipeline explosion that took place in Manitoba on Saturday. The explosion and ensuing shortage is affecting customers in eastern North Dakota, and western Wisconsin as well.

Along with the shortages of natural gas, electric companies are asking their customers to turn their thermostats down to 60 degrees in order to head off possible electrical outages from overtaxed grids as temperatures fall. PJM Interconnection has asked for voluntary conservation in 13 states and the District of Columbia.

Airlines continue to cancel flights with as many as 3,000 grounded flights by Tuesday morning.

In Pennsylvania, Illinois and Ohio, a weather phenomenon called snow rollers took place as snow and high winds drove snow across the landscape rolling snow into tens of thousands of large snowballs.

NOAA reported today that “a wintry mix is possible as far south as southern LA, extending along the Gulf coast into northern FL and northeastward along the Southeast coast into the Carolinas. Significant icing appears quite probable across portions of southern GA into coastal SC and southeastern NC. A swath of light to moderate snows is likely further to the north and west, with heavy snows possible across northeastern NC into the Hampton Roads region of VA.” Along the Carolina coast and Virginia, forecasters are predicting up to a foot of snow.
