With a winter storm warning in effect for Lowcountry counties, forecasters are calling for increased snow totals to fall across the area mixed with ice and sleet. Storm Team 2 Chief Meteorologist Rob Fowler said Lowcountry counties can expect to see between 3 to 5 inches of snow,

For example, Lake Charles, La., along the Gulf Coast, showed snowfall rates of over 1 inch per hour this morning and early afternoon and visibility down to a quarter of a mile with blowing snow. This is one of the reasons why blizzard warnings were posted briefly for that region earlier.

A winter storm sweeping through the U.S. South on Tuesday was dumping snow at levels millions of residents haven't seen before. Moisture from the Gulf of Mexico was combining with a low-pressure system and chilly air to drop significant amounts of snow in some spots.
