A Winter Storm Warning is in effect for the following counties in our area: Horry (except coastal areas), Georgetown (except coastal areas), Florence, Marion, Marlboro, Dillon, Darlington, Robeson and Scotland from 7PM Tuesday through 3AM Thursday. Everything is coming together for another winter storm to impact the Carolinas Tuesday through early Thursday morning. Cold air is rushing into the area Monday night. On Tuesday, moisture rides up and over the shallow layer of cold air setting the stage for a prolonged period of wintry precipitation for much of the area, especially inland.
While some wintry precipitation is possible Tuesday morning, the best chance arrives during the afternoon. With cold air in place, precipitation may begin as rain, snow and sleet inland and sleet and rain along the Grand Strand. Precipitation will become more widespread in the afternoon fron south to north. There may be a brief break in preciptationTuesday evening before more substantial precipitation returns Tueday night through Wednesday. With warm air working in aloft, any sleet and snow will likely chance to freezing rain inland and ice accumulations could be significant.
Here's our best estimate of what will happen in your area.
Little River, Longs, Loris, Conway, North Myrtle Beach, Carolina Forest, Myrtle Beach, Socastee, Garden City, Surfside, Murrells Inlet, Pawleys Island and Georgetown. - Some sleet to start, but eventually it changes to mainly rain, especially along the coast. If the air is colder than our current thinking, we could have a period of freezing rain in Conway, Loris and Longs Tuesday night and Wednesday morning, but accumulations are not likely. Bottom-line, this is mainly a rain event for the Grand Strand.
Darlington, Hartsville, Lake City, Johnsonville, Dillon, Marion, Mullins, Aynor & Kingstree - A very tricky forecast here with all types of precipitation possible. Some rain, sleet and snow Tuesday morning will become more widespread during the afternoon. More sleet and freezing rain are likely Tuesday night through Wednesday. 1" - 2" of snow and sleet are possible, but freezing rain is the big concern. Areas along the I-95 corridor have the highest threat for significant freezing rain that could total more than .50". That's more than enough to produce scattered to widespread power outages.
Lumberton, Red Spring, Bennettsville, Cheraw, Laurinburg and Maxton - Snow and sleet may not get started until the afternoon Tuesday then continue into early Wednesday morning. Through the day Wednesday, snow and sleet may change to mainly sleet and freezing rain. 2" - 4" sleet and snow are possible with around .25" of freezing rain on top of that.
Needless to say, travel will be seriously impacted Tuesday afternoon through Thursday, especially inland.
