Which radars cover Sebastian?

The closest NEXRAD Doppler radar is KBRO (Brownsville, TX), about 38 miles 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 Sebastian	View
KBRO Brownsville, TX	38 mi southeast	2,500 ft	Excellent — the lowest scan sees close to the ground
KCRP Corpus Christi, TX	101 mi north	9,700 ft	Fair — the beam can pass over shallow snow and low-level rotation
KEWX San Antonio, TX	233 mi north	37,800 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.
