Which radars cover Johnsonville?

The closest NEXRAD Doppler radar is KLTX (Wilmington, NC), about 59 miles east-northeast. 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 Johnsonville	View
KLTX Wilmington, NC	59 mi east-northeast	4,500 ft	Good — most storms and steady rain or snow show clearly
KCAE Columbia, SC	97 mi west	9,100 ft	Fair — the beam can pass over shallow snow and low-level rotation
KCLX Charleston, SC	122 mi southwest	13,100 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.
