Which radars cover Castella?

The closest NEXRAD Doppler radar is KMAX (Medford, OR), about 66 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 Castella	View
KMAX Medford, OR	66 mi north-northwest	5,300 ft	Good — most storms and steady rain or snow show clearly
KBHX Eureka, CA	115 mi west-southwest	11,900 ft	Limited — the beam overshoots the lowest part of storms
KBBX Beale AFB, CA	121 mi south-southeast	12,900 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.
