A reinforcing cold air mass will push nighttime lows into the low 30s across western North Carolina and the Upstate of South Carolina Tuesday night into Wednesday morning, with a second round of cold settling in Wednesday night through Thursday morning. Frost formation is likely where skies clear and winds calm, especially between 2 a.m. and 9 a.m.

Why it matters

The sudden cold snap poses a threat to sensitive vegetation, early blooms, and outdoor plumbing across the region. Residents will need to take precautions to protect plants, pets, and property from the freezing temperatures.

The details

Mountain towns including Boone, Burnsville, and Newland are expected to see the coldest readings, ranging from 28°F to 31°F. Asheville could bottom out near 30°F, while foothill communities like Hickory and Lenoir hover in the mid-30s. Farther south, Greenville, Spartanburg, and Anderson remain just above freezing in the upper 30s to near 41°F, but patchy frost may still develop in low-lying areas.

  • Tuesday night into Wednesday morning, temperatures will drop into the low 30s.
  • Wednesday night through Thursday morning, a second round of cold will settle in.
  • Between 2 a.m. and 9 a.m., frost formation is likely where skies clear and winds calm.
