Columbia, SC – Temperatures plunging to 33°F overnight will create widespread frost across central South Carolina and the CSRA by 1 a.m. Thursday, posing a risk to early morning travel and sensitive vegetation.
According to the National Weather Service in Columbia, a Frost Advisory is in effect from 1 a.m. to 9 a.m. EDT Thursday, covering areas including Richland, Lexington, Aiken, Sumter, and Richmond counties. Clear skies and calm winds will allow rapid cooling, leading to frost development on exposed surfaces before sunrise.
In the Midlands, including Columbia, Lexington, and Sumter, frost is expected on vehicles, rooftops, and grassy areas during the early morning commute. Along the Georgia border, cities such as Augusta, Evans, and Thomson will see similar conditions, with colder pockets in rural and low-lying areas.
The primary concern is damage to agriculture and landscaping. Tender plants, spring blooms, and backyard gardens are especially vulnerable at temperatures near freezing. Residents should cover plants, bring potted vegetation indoors, and avoid leaving irrigation systems running overnight.
Temperatures will rebound after 9 a.m., but additional cold mornings remain possible through late week, and more advisories could be issued if conditions persist.
