Which radars cover Lewiston?

The closest NEXRAD Doppler radar is KBHX (Eureka, CA), about 78 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 Lewiston	View
KBHX Eureka, CA	78 mi west	6,700 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMAX Medford, OR	96 mi north	9,000 ft	Fair — the beam can pass over shallow snow and low-level rotation
KBBX Beale AFB, CA	104 mi southeast	10,200 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.
