Open live radar for San Antonio What TALON shows

Which radars cover San Antonio?

The closest NEXRAD Doppler radar to San Antonio, TX is KEWX (San Antonio), about 34 miles to the northeast. Radar beams climb as they travel because the Earth curves away underneath them, so the height of the lowest scan over a city decides how much of a storm's base the radar can see.

Radar	Distance	Lowest beam over San Antonio	View of low-level rotation
KEWX San Antonio, TX	34 mi northeast	2,100 ft	Excellent — the lowest scan is close to the ground, where tornadoes form
KDFX Laughlin AFB, TX	108 mi west	10,800 ft	Fair — the lowest scan is already well above the ground
KGRK Central Texas, TX	112 mi northeast	11,400 ft	Fair — the lowest scan is already well above the ground

Beam height is the center of the 0.5° scan above the radar, using standard atmospheric refraction. Hills and buildings near the radar can block it further.

On TALON you get San Antonio's live radar loop, storm tracks with arrival times and NWS warnings free; close-up radar and rotation detection are part of TALON Pro.
