On Monday, June 12, a cold front approached the state, triggering afternoon thunderstorms. In the Upstate, minor storm damage was reported in Pickens and Spartanburg counties. Lightning struck the tarmac at the Greenville-Spartanburg International Airport and caused a structural fire in Reidville. At the coast, wind damage was reported in Jasper and Beaufort counties, and the station at the Beaufort MCAS recorded a maximum wind gust of 53 mph. On Tuesday, the front pushed slowly toward the coast and triggered a few isolated showers. High temperatures were in the upper 70s to upper 80s, between five and ten degrees below normal.
By mid-week, the front weakened and lifted north, allowing for more scattered showers and storms on Wednesday and Thursday. Strong thunderstorm winds downed trees in Canadys and Ruffin in Colleton County, and there were additional wind damage reports in Jasper and Beaufort counties. Severe storms produced hail up to 1.75 inches and strong winds on Thursday, causing damage in Salem in Oconee County and near Six Mile in Pickens. Wind damage was also reported in Anderson and Spartanburg Counties.
Headed into the weekend, drier air started to move into the area providing sunshine and low rain chances. On Saturday, a second cold front provided a reinforcing shot of drier air into the region. High temperatures on Saturday were closer to average values, reaching the mid-80s to near 90 degrees at the coast. On Sunday, onshore winds contributed to higher tides and caused shallow coastal flooding along low-lying areas.

Most of the rain reported during the period came from a warm front that lifted across the state on Sunday, June 11, with totals ending on Monday morning. Totals from one to three inches across the Midlands and Upstate, with some locations measuring isolated amounts over three inches. The remained of the period was mostly dry, with scattered afternoon showers on Wednesday and Thursday. The abnormally dry (D0) conditions across a portion of the Upstate, northern Midlands and Pee Dee regions continued to persist on the Thursday, June 15, release of the United States Drought Monitor map.
With a lack of widespread rainfall during the period, some gauges in the upper Saluda and Broad watersheds continued to report streamflow values below normal. Elsewhere, the 14-day average streamflow values dropped from above normal to near normal due to the dry conditions. The values reported on the Little Pee Dee River near Galivants Ferry continued to be much below normal. While river height gauges across the state remained below the action stage, coastal flooding was reported at the beginning of the period.
