Which radars cover Downieville?

The closest NEXRAD Doppler radar is KBBX (Beale AFB, CA), about 44 miles west. 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 Downieville	View
KBBX Beale AFB, CA	44 mi west	3,000 ft	Good — most storms and steady rain or snow show clearly
KRGX Reno, NV	73 mi east	6,000 ft	Fair — the beam can pass over shallow snow and low-level rotation
KDAX Sacramento, CA	88 mi south-southwest	7,900 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.
