Greenville–Spartanburg, SC – Residents across Upstate South Carolina and the western North Carolina foothills woke to shimmering rooftops and frost-covered fields early Saturday morning as the coldest air of the season settled into the region. Temperatures dipped into the mid-30s, triggering the season’s first Frost Advisory and signaling the true arrival of November chill.
The Incident: Early Frost Blankets the Upstate
According to the National Weather Service in Greenville–Spartanburg, a Frost Advisory remains in effect until 9 a.m. Saturday, warning residents to protect sensitive outdoor plants from damage.
“Temperatures early this morning have fallen into the low to mid-30s across the foothills,” meteorologists reported. “Gardeners and growers should take precautions to prevent frost damage.”
The frost formed under clear skies and calm winds, allowing ground temperatures to drop quickly overnight. Homeowners in Greenville, Spartanburg, and Gaffney reported thin layers of ice on car windshields and lawns sparkling with a pale white coating before sunrise.
Investigation and Evidence: What’s Behind the Chill
Meteorologists explain that this first widespread frost is the result of a high-pressure system that settled over the Carolinas, creating ideal radiational cooling conditions. With light winds and dry air, temperatures dropped several degrees lower than average for early November.
This early frost serves as a reminder of the region’s transition into late fall, where sharp nighttime drops can follow mild afternoons. Fortunately, no freezing temperatures are expected, meaning the frost will cause only minor damage to unprotected plants.
Weather Pattern and Forecast Details
Skies will remain clear and calm through Saturday, helping temperatures rebound by the afternoon. Highs are expected to reach the lower 60s, offering a pleasant fall day for outdoor projects, hikes, or early holiday decorating.
By Sunday afternoon, clouds will begin to build ahead of an approaching weak low-pressure system moving in from the west. This will introduce a 30 percent chance of light rain Sunday night, primarily after 10 p.m.
Forecasters note that no severe weather or heavy rainfall is expected, though roads along I-85 and I-26 may become damp overnight.
“We’re not expecting any stormy weather,” meteorologist Scott Krentz with the NWS said. “Just a few passing showers as the next front slides through.”
Statements and Reactions from Officials
Local officials and agricultural experts are advising residents to cover plants and move potted flowers indoors to minimize frost damage. Home improvement stores across Greenville and Spartanburg reported increased sales of plant covers and tarps ahead of the advisory.
Local grower Susan McMillan from Taylors shared,
“This kind of early frost isn’t unusual, but it can sneak up on you. A single cold morning like this can hurt tender plants if you’re not prepared.”
Background Context: The Transition to November Weather
The Upstate’s November climate often swings between frosty mornings and mild afternoons, a pattern typical for this time of year. According to long-term climate data, Greenville averages one to two frost events before mid-November, often preceding a stretch of milder temperatures.
As the jet stream shifts southward, cool air masses from the Midwest occasionally dip into the Carolinas, creating the chilly starts that mark the change of seasons.
Ongoing Developments and Five-Day Outlook
Looking ahead, temperatures will gradually warm through midweek, providing a pleasant stretch of autumn weather following Sunday night’s light rain.

- Saturday: 62°/37° – Frost early; sunny and calm.
