Which radars cover Graton?

The closest NEXRAD Doppler radar is KDAX (Sacramento, CA), about 64 miles east. 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 Graton	View
KDAX Sacramento, CA	64 mi east	5,000 ft	Good — most storms and steady rain or snow show clearly
KBBX Beale AFB, CA	99 mi northeast	9,400 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMUX San Francisco, CA	103 mi south-southeast	10,100 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.
