Greenville Spartanburg Asheville Anderson, SC, August 13, 2026 —
Residents across the Western Carolinas, with a particular focus on areas like Greenville, are preparing for a prolonged period of dangerous heat. Heat index values are forecast to surpass 100 degrees Fahrenheit, a situation expected to persist from Friday through Tuesday.
The extreme and persistent high temperatures are attributed to a meteorological phenomenon known as a heat dome. This occurs when an upper-level ridge of high pressure becomes stagnant, trapping hot air over a region and preventing cooler air masses from moving in. This atmospheric setup is leading to the anticipated heatwave, with forecasts indicating little to no overnight relief from the oppressive conditions.
While there is a possibility of isolated thunderstorms developing, these are not expected to significantly alleviate the overarching threat posed by the extreme heat. The primary concern remains the duration and intensity of the high temperatures, which could pose risks to public health and infrastructure.
Officials are advising residents to take necessary precautions to stay safe during this period of extreme heat. Further details regarding specific health advisories or public safety measures are expected as the heatwave progresses.
