Which radars cover Walnut Grove?

The closest NEXRAD Doppler radar is KDAX (Sacramento, CA), about 19 miles north-northwest. 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 Walnut Grove	View
KDAX Sacramento, CA	19 mi north-northwest	1,100 ft	Excellent — the lowest scan sees close to the ground
KMUX San Francisco, CA	78 mi south-southwest	6,700 ft	Fair — the beam can pass over shallow snow and low-level rotation
KBBX Beale AFB, CA	86 mi north	7,700 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.
