Even with high pressure over the area on Monday, June 3, a typical summer pattern continued, with increasing afternoon and evening storm chances, heat, and humidity through Thursday. Morning lows were in the 60s, and highs through the middle of the week were in the upper 80s and low 90s.
A stalled frontal boundary along the coast on Tuesday lead to partly to mostly cloudy skies over the region, with a chance of showers and thunderstorms in the afternoon and early evening. While the threat of severe and heavy rainfall remained low, strong storms and localized downpours occurred. There were reports of trees down in Calhoun, Fairfield, Lexington, and Saluda counties.
An approaching front and upper trough on Thursday brought another round of storms, and a few storms were strong to severe. Early Thursday morning, heavy rain, between two and four inches, fell across portions of the Lowcountry, especially in Charleston and Colleton counties. A USGS rain gauge near Jacksboro recorded 4.39 inches of rain in three hours.
Behind the front, high pressure filtered back into the area, bringing drier air and fair conditions to the region on Friday and Saturday. Another approaching front produced severe thunderstorms in the northern Midlands late Sunday evening, causing wind damage in Fort Lawn and Great Falls. This prompted the National Weather Service to conduct storm surveys the following morning.

Most locations across the state recorded half an inch of rain during the period, with portions of the Central Savannah River Area and the Upper Savannah River basin reporting up to three inches of rain. A few CoCoRaHS observers in Greenwood County and coastal portions of Charleston and Colleton counties measured up to four inches of rain. Due to multiple periods of dry weather, the U.S. Drought Monitor expanded the abnormally dry conditions (D0) across portions of the Lowcountry and Midlands.
Despite rainfall from showers and thunderstorms during the period, 14-day average streamflow values at gauges across the state decreased, with some gauges reporting flows below average. River height gauges across the state remained below the action stage, and gauges within the Coastal Plain fell below the action stage due to the relatively dry week.
