On Monday, November 27, a cold front moved through the area during the morning, bringing much drier and colder air into the region. Cloudy conditions gave way to sunny skies, and daytime temperatures across the state reached the mid to upper-50s. By Tuesday morning, low temperatures dropped into the upper 20s and low 30s as high pressure settled over the area. A reinforcing cold front moved through the area late Tuesday, with minimum temperatures up to fifteen degrees below normal on Wednesday morning. The National Weather Service (NWS) station at the Greenville-Spartanburg International Airport reported a low of 21 degrees, breaking the record of 23 degrees in 1967. The coastal region was the only area that did not record temperatures below freezing. Maximum temperatures there were still below normal, with highs in the low to mid-50s.
While morning temperatures remained cooler than usual, a warming trend began on Thursday that lasted through the rest of the period. Daytime temperatures were back to normal for the end of November, with high temperatures reaching the upper 50s to low 60s. High pressure continued to keep conditions dry, but clouds increased throughout the day.
On the first day of climatological winter, wedge conditions kept high temperatures slightly below average in the Upstate, with temperatures in the mid-50s. However, maximum temperatures were up to ten degrees above average across the Lowcountry, Midlands, and Pee Dee. The NWS station at the Columbia Metropolitan Airport CAE observed a high of 71 degrees, and the high reached 76 degrees at the NWS Charleston International Airport station. The warmer-than-normal temperatures continued over the weekend, with overnight temperatures over twenty degrees above normal, lows were in the 50s and 60s, and daytime temperatures in the upper 60s to mid-70s. An area of low pressure south of the region provided isolated and scattered showers over the weekend.

Rainfall was sparse during the seven days, with less than a tenth of an inch recorded across much of the state. Only stations in the Upstate reported rainfall totals over a quarter of an inch, mainly in portions of Greenville, Oconee, and Pickens counties. The US Drought Monitor (USDM) map released on November 23 showed some improvements due to widespread precipitation from the previous period. The spatial extent of extreme (D3) conditions decreased across parts of the Upstate, and the rain from the previous period eased severe (D2) and moderate drought (D1) conditions in other parts of the state.
There was minimal change in the 14-day average streamflow values in portions of the Broad, Catawba, Pee Dee, Lynches, and Saluda River basins. Most gauges still showed lingering dry conditions, and the limited rainfall caused a slight improvement in flow values in the Upstate. Many streamflow values were still below the normal range or on the lower end of the normal range. While the river height gauges across the state reported levels below flood stage, tidal gauges reached minor heights early in the period due to astronomically high tides.
