Which radars cover Greenhorn?

The closest NEXRAD Doppler radar is KBBX (Beale AFB, CA), about 54 miles west-southwest. 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 Greenhorn	View
KBBX Beale AFB, CA	54 mi west-southwest	4,000 ft	Good — most storms and steady rain or snow show clearly
KRGX Reno, NV	70 mi east	5,600 ft	Good — most storms and steady rain or snow show clearly
KDAX Sacramento, CA	109 mi south-southwest	10,900 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.
