WEEKLY SOUTH CAROLINA WEATHER 2022

June 6, 2022 - June 12, 2022

WEATHER SUMMARY:

A dry high pressure remained in control of the weather pattern through the middle of the week, with temperatures near normal. Overnight lows were observed in the 60s, while highs reached the low to mid-80s in the Upstate and the upper 80s to low 90s elsewhere across the state. An area of low pressure developed along a stalled front in south-central Georgia by Tuesday morning, triggering some storms in Beaufort County. Most of the state remained dry as high pressure shifted offshore ahead of a cold front on Wednesday.

On Thursday, a slow-moving cold front pushed into the region, triggering isolated and scattered showers and thunderstorms along the South Carolina coast. Thunderstorms in Beaufort County produced strong winds, including a wind gust of 47 mph at Beaufort MCAS and a 51-mph gust recorded at the Beaufort County Airport. Damage to small sheds, patio furniture, and trees near Conway in Horry County was caused by a downburst.

Drier air worked into the region behind the front that stalled along the coast. Over the weekend, a weak area of low pressure formed offshore of the southern Lowcountry, bringing increased rain chances in the eastern half of the state. A slow-moving thunderstorm over a portion of Richland County produced nearly an inch of rain in 45 minutes, causing flash flooding in the Five Points area of Columbia. High pressure moved into the region on Sunday, and temperatures rose into the upper 90s, between five and ten degrees above normal.

The Charleston Harbor Tidal Gauge recorded the first high astronomical tides due to the June King Tide event. The tidal levels ranged between 7.0 feet and 7.2 feet MLLW starting on Saturday and Sunday, which caused shallow flooding to low-lying coastal areas.

(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 97 degrees on June 12 at the NWS stations near Barnwell and the Florence Regional Airport.
The lowest temperature reported was 49 degrees at the NWS station near Jocassee in Oconee County on June 7.
The maximum 24-hour precipitation reported was 1.09 inches at the NWS station Walterboro in Colleton County, ending on the morning of June 9.
The CoCoRaHS station Hilton Head Island 4.7 NW (SC-BF-104) reported a 24-hour precipitation total of 2.55 inches, ending on the morning of June 9.
The state average precipitation for the seven-day period was 0.6 inches.

SOIL TEMPERATURES:

4-inch depth soil temperature: Clinton: 80 degrees. Columbia: 80 degrees. Barnwell: 75 degrees. Mullins: 73 degrees.

PRECIPITATION AND RIVER STAGES:

Most of the state recorded less than a tenth of an inch of rain during the period, though some isolated locations in the Coastal Plain measured between one and two inches. However, CoCoRaHS observers on Hilton Head Island reported between four and five inches over the seven days. Unfortunately, the lack of rain in the Midlands led to a reintroduction of abnormally dry conditions (D0) on the United States Drought Monitor. Despite some rainfall totals of over two inches in the coastal Lowcountry, severe drought (D2) conditions persisted in Beaufort and Jasper counties, and moderate drought (D1) designations remained in place across areas east of Interstate 95.

With the lack of widespread rainfall during the period, the 14-day streamflow averages at many of the gauges of the four main watersheds dropped to well-below normal thresholds. The gauge on the North Tyger River near Fairmont joined the Little Pee Dee River at Galivants Ferry, recording values below 10% of their average streamflow. All the state’s rivers observed heights below the flood stage, although a round of King Tides caused coastal gauges to rise to minor and moderate flood stages.

WATER TEMPERATURES:


Charleston Harbor (CHTS1): 82.6 degrees.
Capers Nearshore Buoy (Station 41029): 80.4 degrees.
Fripps Nearshore Buoy (Station 41033): 81.5 degrees.
