Greenville, SC – Gardeners and growers across western North Carolina have a narrow window to act as temperatures drop toward freezing overnight, creating conditions for frost that could damage sensitive plants by sunrise.
According to the National Weather Service in Greenville-Spartanburg, lows will fall into the low to mid-30s across the North Carolina mountains between 3 a.m. and 7 a.m. Wednesday, with colder pockets near 30°F in higher elevations. Frost development is most likely in sheltered valleys around Asheville, Boone, and Burnsville.
The threat expands Wednesday night into early Thursday, reaching parts of the foothills and northwest Piedmont, including Hickory, Lenoir, and areas near Morganton. Temperatures again dip into the low 30s, allowing frost to form where winds remain light and skies clear.
While South Carolina locations like Greenville and Spartanburg stay milder in the upper 30s to low 40s, patchy frost cannot be ruled out in outlying rural areas.
Residents should cover or bring in sensitive vegetation, especially early-season crops and flowering plants. Frost conditions will ease after sunrise each day, but additional advisories may be issued as colder nights continue through midweek.
