The climatological start to summer began on Monday, June 1. The 12:53 p.m. temperature at Columbia's Hamilton-Owens AP of 88 degrees fell 18 degrees by 2:00 p.m. during a thunderstorm. Scattered storms over Fairfield and Lancaster counties produced one-inch diameter hail. Chesterfield received rains of 1.42 inches. Holly Hill reported a Tuesday minimum temperature of 63 degrees and it was 64 degrees in Johnston. Drenching rains on Tuesday night brought 2.45 inches in three hours to Columbia's Hamilton-Owens AP and intensity rates of 0.48 inches in 5 minutes (part of 2.92 inches in one hour) to the USGS gage at the N Fork Edisto River near Orangeburg. More flooding rains developed into early Wednesday morning across central counties and over to the coast along a nearly stationary boundary. Two CoCoRaHS volunteers within one quarter of a mile to each other in McClellanville measured 5.80 and 5.66 inches respectively. Heavy rains left 2.53 inches in Cheraw, 2.33 inches at the Charleston AP and 2.12 inches in Saluda. Nearly constant thunder late Wednesday night made for interrupted sleep and flash flooding for Lexington and Richland counties. Upper level convergence over a stalled front caused localized torrential downpours within the Columbia metropolitan area. The USGS rain gage at Brookland Cayce High School measured intensity rates of up to 2.48 inches in 30 minutes on Thursday morning between 1:15 and 1:45 a.m., 6.28 inches in just over six hours and a running total that began on June 1 of 9.66 inches. The USC campus gage recorded a 24-hour rainfall of 4.70 inches with street flooding in Five-Points and downstream of Rocky Branch Creek. The gage at McTier Creek in Monetta measured 5.17 inches and Clarks Hill reported 4.00 inches. Thursday's cloudy weather and 78-degree high temperature at Winnsboro was 10 degrees below the date average for that location. The 5.86 inches measured at Columbia Metro AP for June's first four days was the most for so early in that location's June recordkeeping. On Friday morning, Chester and Union cooled to 59 degrees with drying sunshine observed well inland. Mostly sunny conditions on Saturday moved the thermometer to 90 degrees at the Rock Hill AP, Little Mountain and the Conway AP. Isolated thundershowers brought Long Creek in Oconee County 0.98 inches of rain and the Georgetown AP 1.14 inches of rain. Partly sunny weather on Sunday included scattered thunderstorms. The Greenwood and Orangeburg airports both warmed to an afternoon high temperature of 88 degrees. The state average temperature for the seven-day period was near the long-term average.
