WEEKLY SOUTH CAROLINA WEATHER 2023

March 6, 2022 - March 12, 2023

WEATHER SUMMARY:

On Monday, March 6, a dry high pressure over the region provided fair weather and partly cloudy skies. A weak, dry front moved through Tuesday morning, bringing breezy conditions to area lakes late Tuesday into Wednesday morning. High temperatures were up to twenty degrees above average despite the frontal passage. A few locations set new daily record high temperatures, including 87 degrees recorded at the National Weather Service (NWS) stations at Charleston International Airport and Beaufort Marine Corps Air Station.

Behind the front, an extremely dry air mass on Wednesday afternoon contributed to elevated fire danger conditions. While high temperatures were cooler than earlier in the week, in the 60s, they were closer to seasonable values for the beginning of March. The beautiful weather lasted until late on Thursday when increasing cloudiness developed overnight, bringing a return to unsettled weather. A cold front on Friday triggered some scattered showers and a few thunderstorms in the Lowcountry.

After the frontal passage, there was a brief reprieve as drier air filtered back into the region. On Saturday, a cooler air mass arrived with temperatures about five degrees below normal, starting in the 40s and only rising into the upper 50s to low 60s. Seasonable conditions continued overnight before a low-pressure system brought moisture back to the region, and widespread rain developed by late morning. A cold air wedge also set up across the state, and temperatures in the Upstate struggled to get out of the upper 40s, while closer to the coast, temperatures reached the upper 60s. Rain tapered off by the early evening as drier air filtered back into the region for the beginning of the work week.

(Note: The highest and lowest official temperatures and highest precipitation totals provided below are based on observations from the National Weather Service (NWS) Cooperative Observer network and the National Weather Service's Forecast Offices.)
The highest temperature reported was 87 degrees on March 7 at the Beaufort Marine Corps Air Station and at the NWS station at the Charleston International Airport.
The lowest temperature reported was 31 degrees at the NWS station near Jocassee in Oconee County on March 7.
The maximum 24-hour precipitation reported was 1.00 inches at the NWS Long Creek in Oconee County, ending on the morning of March 12.
The CoCoRaHS station Tamassee 0.9 NW (SC-OC-95) reported a 24-hour precipitation total of 1.33 inches, ending on the morning of March 12.

SOIL TEMPERATURES:

4-inch depth soil temperature: Clinton: 47 degrees. Columbia: 60 degrees. Barnwell: 52 degrees. Mullins: 49 degrees.

PRECIPITATION AND RIVER STAGES:

Most of the state recorded at least half an inch of rainfall, though some areas received more and less. Parts of Oconee and Pickens counties, along with most of the lower Savannah River basin, measured more than an inch, with few isolated locations reporting close to an inch and a half. Elsewhere, rainfall was sparse in interior portions of the Pee Dee, especially near Darlington and Marlboro counties.

During the past few weeks, the 14-day averages for stream flow values across much of the state started to decline due to the lack of consistent rainfall across the region. Most stream flow gauges in the major river basins across the state reported values slightly below normal conditions, with more gauges dropping to much below normal flows. However, rain toward the end of the period improved a few streamflow values, though those in the Pee Dee region remained below average. Most river heights returned to levels below the action stage.

WATER TEMPERATURES:


Charleston Harbor (CHTS1): Not Available.
Capers Nearshore Buoy (Station 41029): Not Available.
Fripps Nearshore Buoy (Station 41033): 62.6 degrees.
