Which radars cover Union?

The closest NEXRAD Doppler radar is KLGX (Langley Hill, WA), about 50 miles west-southwest. 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 Union	View
KLGX Langley Hill, WA	50 mi west-southwest	3,600 ft	Good — most storms and steady rain or snow show clearly
KATX Seattle/Tacoma, WA	65 mi north-northeast	5,100 ft	Good — most storms and steady rain or snow show clearly
KRTX Portland, OR	113 mi south	11,600 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.
