Which radars cover Helotes?

The closest NEXRAD Doppler radar is KEWX (San Antonio, TX), about 40 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 Helotes	View
KEWX San Antonio, TX	40 mi east-northeast	2,700 ft	Excellent — the lowest scan sees close to the ground
KDFX Laughlin AFB, TX	99 mi west-southwest	9,400 ft	Fair — the beam can pass over shallow snow and low-level rotation
KGRK Central Texas, TX	111 mi northeast	11,200 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.
