Which radars cover Hornitos?

The closest NEXRAD Doppler radar is KHNX (San Joaquin Valley, CA), about 89 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 Hornitos	View
KHNX San Joaquin Valley, CA	89 mi south-southeast	8,000 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMUX San Francisco, CA	94 mi west-southwest	8,800 ft	Fair — the beam can pass over shallow snow and low-level rotation
KDAX Sacramento, CA	104 mi northwest	10,300 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.
