SC Swelters: Heat Dome Grips Upstate Through September
31 Aug
Summary
- Upstate South Carolina faces persistent high heat and humidity.
- Heat index values are expected to reach 97-100 degrees through Labor Day.
- A heat dome expansion could significantly impact the region's weather.
As August concludes, the Upstate region of South Carolina is set to experience a continuation of summer heat into the first week of September. The National Weather Service in Greenville-Spartanburg forecasts high temperatures and humidity, with heat index values likely to range between 97 and 100 degrees Fahrenheit through Labor Day weekend.
A powerful heat dome originating over the Ozarks is predicted to shift eastward, potentially encompassing Upstate South Carolina. This system is expected to drive daily high temperatures into the mid- to upper-90s by September 1st and 2nd. The prolonged period of excessive heat and humidity, with dewpoints in the low 70s, could extend through September 4th.
While a weak cold front might offer a slight reprieve between September 4th and 5th, its impact remains uncertain. Meteorologists note that the El Niño pattern may contribute to warmer-than-average temperatures across South Carolina this fall. Residents in areas like Greenville, Spartanburg, and Anderson are advised to limit strenuous outdoor activities and stay hydrated during this period of early September heat.
