The main weather story for the week was the tranquil conditions and the near-normal maximum and minimum temperatures, with low temperatures in the upper 60’s to low 70’s, and daytime highs reaching the upper 80’s to mid-90’s.
On the morning of Monday, June 24, some of the mountainous stations recorded minimum temperatures in the low 60’s, such as the National Weather Service station at Caesars Head which reported a morning low of 61 degrees. An upper-level disturbance, associated with a weak cold front, helped promote scattered thunderstorms during the afternoon. Some of the storms produced strong winds in portions of the Upstate, causing downed trees in Abbeville, Cherokee, Greenwood, Greenville, Laurens, Newberry and Spartanburg counties. The 24-hour CoCoRaHS rainfall totals ending on the morning of Tuesday, June 25, showed the heaviest rainfall in the Upstate, with over an inch reported by CoCoRaHS observers in Anderson, Greenville and Spartanburg counties. Some totals near half an inch were reported across the Midlands, and areas south of the Interstate 95 corridor reported a Trace or no rainfall. The warm conditions continued after the disturbance moved through the region but high-pressure helped suppress shower activity and provided some drier air across the Palmetto State through Wednesday.
By Thursday, June 27, the typical summertime afternoon and evening thunderstorms returned in parts of the Upstate, where thunderstorms downed trees and power lines in Anderson and Oconee counties. Scattered showers developed along the sea breeze and a storm spotter reported pea-sized hail southwest of Moncks Corner, near Cane Bay. The daily rainfall totals ending on the morning of Friday, June 28, were highest in the Upstate (2.00 inches from a CoCoRaHS observer near Seneca) and near Lake Wylie (1.83 inches). Minimum temperatures continued to range from the upper 60’s to low 70’s, with maximum temperatures in the upper 80’s to mid-90’s through the weekend.
Early Saturday morning, pictures of waterspouts offshore of Edisto Island, Seabrook Island and Sullivan’s Island were relayed to the National Weather Service Office in Charleston. Rainfall totals from the isolated thunderstorms in the Lowcountry were highest in the Goose Creek/Summerville area, with a CoCoRaHS station report of 2.04 inches in Summerville. Maximum temperatures on Sunday, June 30, were slightly warmer, with highs in the low to upper 90’s ahead of a forecast period of excessive heat heading into the upcoming week.

Rainfall totals over the seven days were varied across the Palmetto State, with some localized areas of the Upstate observing more than two inches of rain while other locations in the Midlands and Pee Dee regions received less than half an inch. The sparse rainfall over much of the state caused stream levels to continue to fall and remain below critical flood thresholds by the end of the period. Similarly, streamflow values in areas that received the heaviest rainfall totals increased and remained slightly above normal through the weekend. The year-to-date rainfall totals in the Upstate remained well above normal for this time of year, with more than 20 inches reported at many locations and over 40 inches in some of the more mountainous areas. Fifteen to twenty inches of rain have fallen since the beginning of the year in the Midlands, but even after the rain this weekend, the Central Savannah River Area is close to four inches below normal. Parts of the Lowcountry and Pee Dee continue to be the driest parts of the state, with between ten and fifteen inches of rain for the year in areas from the Interstate 95 corridor to the coast, with isolated totals of over 25 inches in portions of Beaufort, Charleston and Colleton counties. In areas that have missed the beneficial rainfall, the totals are six to eight inches below normal for this time of year, with portions of Georgetown County close to twelve inches below normal.
