Which radars cover Longview?

The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 30 miles south. 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 Longview	View
KRTX Portland, OR	30 mi south	1,800 ft	Excellent — the lowest scan sees close to the ground
KLGX Langley Hill, WA	86 mi northwest	7,700 ft	Fair — the beam can pass over shallow snow and low-level rotation
KATX Seattle/Tacoma, WA	143 mi north	16,900 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.
