Which radars cover Monmouth?

The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 61 miles north-northeast. 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 Monmouth	View
KRTX Portland, OR	61 mi north-northeast	4,700 ft	Good — most storms and steady rain or snow show clearly
KLGX Langley Hill, WA	162 mi north-northwest	20,600 ft	Limited — the beam overshoots the lowest part of storms
KMAX Medford, OR	193 mi south	27,600 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.
