Greenville is waking to clear skies and temperatures in the mid-70s Wednesday, but the comfortable start will fade fast. Sunshine will drive the afternoon high to 97 degrees, with the heat index reaching 103 as light winds offer little relief.
Triple-Digit Heat Index Through Friday
Wednesday will stay sunny with only a 1% chance of rain and east-northeast winds between 1 and 5 mph. The National Weather Service forecasts another high near 97 Thursday, when the heat index could reach 104, followed by a similarly hot and mostly sunny Friday.
Wednesday night will be mostly clear, with temperatures dipping to about 74 degrees, though the heat index could remain near 100. No watches, warnings or advisories are listed in the supplied forecast, but prolonged afternoon exposure will still be rough for anyone working, exercising or running errands outdoors.
Weekend Storm Chances Bring Some Relief
Saturday starts sunny and could again reach 97 degrees before a 30% chance of showers and thunderstorms arrives after 2 p.m. Sunday looks cooler at around 90 degrees, but the rain and storm chance rises to 50% during the afternoon and evening.
Labor Day brings a more noticeable break from the heat, with a partly sunny high near 86 and a 30% chance of showers and thunderstorms. Another chance of storms continues Monday night, when the low could fall to 66 degrees.
Plan Outdoor Time Around The Heat
The National Weather Service recommends drinking plenty of water, taking frequent breaks in shade or air conditioning, and checking on older adults, young children and people working outside, according to its heat safety guidance. Early morning and evening will be the better windows for strenuous activity through Friday, while weekend plans should leave room for a pop-up shower or thunderstorm.
