The period started as the cold front had moved well offshore and a high-pressure system built into the region. Overnight lows on Monday and Tuesday were five to ten degrees below normal, mainly in the mid-30s. Breezy and sunny conditions prevailed through early Tuesday afternoon, with high temperatures climbing into the low 50s in the Upstate and the upper 50s closer to the coast.
Moisture increased across the region late Tuesday, ahead of the next system. Scattered showers started overnight as a low-pressure system formed in the Midwest. By Wednesday morning, a warm front lifted north across the state, creating a widespread rain event that lasted into late afternoon. High temperatures outside of the Upstate climbed into the mid-60s. A few strong thunderstorms produced gusty winds up to 40 mph. The associated cold front moved through late Wednesday and was offshore by Thursday morning.
High pressure settled near the Gulf Coast and provided dry conditions with cooler temperatures on Thursday and Friday. Despite the nearly sunny skies, high temperatures only climbed into the upper 40s in the Upstate and the lower 50s in the Midlands and Pee Dee. On Saturday, the high pressure moved into the Southeast; however, as the pressure continued to shift ahead of the next weather system, clouds increased across the region late in the afternoon. As the next storm approached the area, scattered showers developed on Sunday afternoon, with more widespread rain falling overnight

A cold front midweek provided most of the rainfall across much of the state during the period, though additional rain on Sunday contributed to the overall totals. Widespread totals of over an inch and a half were measured across the state; however, over two inches were recorded in the Central Savannah River Area. Isolated portions of coastal Georgetown and Horry counties reported less than an inch of rain. According to the latest release of the US Drought Monitor, the rain helped remove drought (D1) conditions and eased abnormally dry (D0) conditions in the interior parts of the Lowcountry. However, D1 persisted in coastal portions of the Lowcountry and Pee Dee, while there was a slight decrease in D1 conditions in Dillon and Marion counties.
The multiple rounds of precipitation during the period kept the 14-day averages for stream flow gauges near normal in portions of the Midlands and Upstate. Some tributaries along the Broad and Savannah rivers continued to record stream flows slightly above normal. River heights remained below flood stage in portions of the Upstate. With the consistent precipitation over the past few periods, some river height gauges south of the Fall Line rose into action stage, and a few reached minor flood stage and would continue to rise as water moved through the river basins. Two gauges within the Pee Dee River basin continued to measure flows below average, the Little Pee Dee at Galivants Ferry and Waccamaw River near Longs.
