Greenville is starting Thursday with clear skies and temperatures around 72 degrees, but the easygoing morning will give way to a sunny afternoon near 92, according to the National Weather Service. The bigger heat arrives Friday, when the high could reach 93 before weekend storms move into the forecast.

The National Weather Service Greenville-Spartanburg office expects dry weather Thursday with southwest winds of 2 to 8 mph. No watches, warnings or advisories are listed for the forecast area, though the combination of heat and humidity will make long stretches outdoors feel more taxing.

Friday Brings The Week’s Peak Heat

Friday stays sunny and warmer, with a high near 93 and light southwest winds. A few showers or thunderstorms could develop Friday night, when the rain chance rises to 40% and temperatures settle near 70.

This latest outlook sharpens the forecast from earlier this week, when Greenville was still looking at a cooler and drier stretch before the weekend storm pattern. The updated forecast is available from the National Weather Service.

Saturday Looks Like The Wettest Day

Saturday is expected to bring the best chance for rain, with showers likely before 11 a.m. followed by more showers and thunderstorms through the afternoon. The high should reach about 88, with an 80% chance of precipitation and another round of storms possible Saturday night.

Sunday offers a partial reset, starting mostly sunny before a 40% chance of showers and thunderstorms arrives after 2 p.m. Monday remains hot near 91, with only a slight chance of afternoon storms, so outdoor plans may work best earlier in the day.

Plan Around The Heat And Storm Timing

Thursday and Friday will favor morning or evening errands, outdoor workouts and other heat-sensitive activities. For Saturday, keep plans flexible, allow extra time for wet roads and check the sky before heading out, since the stormiest stretch of the weekend is expected during the daytime.
