Which radars cover Chehalis?

The closest NEXRAD Doppler radar is KLGX (Langley Hill, WA), about 62 miles west-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 Chehalis	View
KLGX Langley Hill, WA	62 mi west-northwest	4,800 ft	Good — most storms and steady rain or snow show clearly
KRTX Portland, OR	66 mi south	5,200 ft	Good — most storms and steady rain or snow show clearly
KATX Seattle/Tacoma, WA	108 mi north-northeast	10,800 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.
