Greenville is starting Tuesday, September 15, under mostly cloudy skies, but the gray opening will not last. Isolated showers are possible around daybreak, followed by partial sunshine and an afternoon high near 86 degrees.

Warm-Up Arrives By Midweek

The National Weather Service expects a partly cloudy night with a low around 66 and northeast winds near 6 mph. Wednesday should be sunny and warmer at about 90 degrees, with temperatures returning to the 90s by Thursday and Friday.

Weekend Storm Chances Build

Saturday will stay sunny for much of the day, with a slight chance of showers and thunderstorms after 2 p.m. Sunday brings a 30% chance of afternoon storms and a high near 90, while Monday brings a 50% chance of showers.

What It Means For Local Plans

Tuesday morning plans may need a light rain layer, but afternoon errands and outdoor activities should get a better weather window. The bigger story is the heat: after today’s relatively mild start, temperatures climb into the low and mid-90s through Friday before storm chances increase over the weekend and into Monday.
