Which radars cover Barnwell?

The closest NEXRAD Doppler radar is KCLX (Charleston, SC), about 45 miles south-southeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.

Radar	Distance	Lowest beam over Barnwell	View
KCLX Charleston, SC	45 mi south-southeast	3,100 ft	Good — most storms and steady rain or snow show clearly
KCAE Columbia, SC	51 mi north-northeast	3,600 ft	Good — most storms and steady rain or snow show clearly
KJGX Robins AFB, GA	122 mi west-southwest	13,000 ft	Limited — the beam overshoots the lowest part of storms

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
