Winter Weather — Greenville Mountains, South Carolina
2021-02-17 to 2021-02-18 · Greenville Mountains, South Carolina
Wider weather episode
Moisture and precipitation overspread the upstate South Carolina late in the evening of the 17th and continued into the morning of the 18th in association with an area of low pressure moving along the Gulf Coast. Enough cold air was in place to allow some of this precipitation to fall as freezing rain above about 2000 feet, until warming temperatures gradually forced a transition to rain from southwest to northeast. Total ice accretion was generally in the .10 to .20 range, with spotty higher amounts. Due to warm road temperatures, accretion was primarily limited to elevated surfaces and limited travel difficulties.
