WEEKLY SOUTH CAROLINA WEATHER 2025
February 17, 2025 - February 23, 2025
WEATHER SUMMARY:
Dry and cool weather returned behind Sunday’s cold front on Monday, February 17. High temperatures were up to ten degrees below normal, rising into the 50s after starting in the lower 30s during the morning. Temperatures warmed slightly on Tuesday but were still below normal. However, on Tuesday, a winter weather advisory was in effect for portions of northeastern SC.
Wednesday morning, temperatures in the Midlands and Upstate were below freezing, and high temperatures barely reached the mid-40s across most of the state. Low pressure moved along the coast on Wednesday and Wednesday night, bringing precipitation. Temperatures were near freezing, and sleet was reported in Chesterfield and Lancaster counties during the afternoon. There were limited impacts from freezing rain on bridges and elevated roadways, with light ice accumulations less than a tenth of an inch. There was a brief period of flurries across portions of the Upstate and Midlands, and the National Weather Service observer at the Greenville-Spartanburg International Airport reported 0.3 inches of snow accumulation. As clouds moved out of the area, the wind gusts increased during the afternoon. The combination of cold temperatures and wind speed led to the National Weather Service issuing Cold Weather Advisories as strong Canadian high pressure and a frigid and dry air mass settled into the central US and extended into the Southeast US for the remainder of the week and weekend.
Despite sunny conditions on Friday, temperatures were up to 20 degrees below normal. Morning lows dropped into the teens to low 20s, with wind chill values in the single digits in the Upstate and teens at the coast. Temperatures only rose into the 40s by late afternoon. The NWS station at Anderson Regional Airport reported a new record low of 16 degrees, breaking the previous record of 20 degrees set in 1959. Temperatures were slightly warmer on Saturday, with highs in the mid-50s, but five to ten degrees below normal. The warming trend continued Sunday, with morning temperatures in the mid-to-upper 30s and afternoon high temperatures reaching the upper 50s to low 60s

PRECIPITATION AND RIVER STAGES:
Rainfall during the period occurred mainly on Wednesday into Thursday morning, with totals ranging from less than a tenth of an inch across most of the Upstate to roughly half an inch reported in portions of Charleston and Horry counties. After the rain, conditions remained dry throughout the rest of the period. The U.S. Drought Monitor map released on Thursday, February 20, showed improvements to the dry and drought conditions across portions of the Fall Line and Upstate due to the heavy rainfall from the previous period. Elsewhere, conditions remained unchanged.
Despite the lack of rainfall, the 14-day average streamflow values at gauges in the Upper Savannah, Santee, Broad, and Catawba River basins continued to report flows above normal. Some gauges in the Midlands recorded flows within normal range; however, gauges in portions of the Lowcountry and Pee Dee regions continued to report values below normal. Some gauges on rivers in the Pee Dee recorded values much below normal, including the gauge on the Little Pee Dee River at Galivants Ferry, Black Creek at Kingstree, and the Waccamaw River near Longs. The height levels at the river and the tidal gauges remained below the flood stage during the period.

Charleston Harbor (CHTS1): 55.2 degrees.
