Which radars cover Rio Vista?

The closest NEXRAD Doppler radar is KDAX (Sacramento, CA), about 22 miles north. 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 Rio Vista	View
KDAX Sacramento, CA	22 mi north	1,300 ft	Excellent — the lowest scan sees close to the ground
KMUX San Francisco, CA	71 mi south	5,800 ft	Good — most storms and steady rain or snow show clearly
KBBX Beale AFB, CA	91 mi north	8,400 ft	Fair — the beam can pass over shallow snow and low-level rotation

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
