Which radars cover Big Lagoon?

The closest NEXRAD Doppler radar is KBHX (Eureka, CA), about 46 miles south. 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 Big Lagoon	View
KBHX Eureka, CA	46 mi south	3,200 ft	Good — most storms and steady rain or snow show clearly
KMAX Medford, OR	97 mi northeast	9,200 ft	Fair — the beam can pass over shallow snow and low-level rotation
KBBX Beale AFB, CA	175 mi southeast	23,300 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.
