Which radars cover Lewisville?

The closest NEXRAD Doppler radar is KRTX (Portland, OR), about 23 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 Lewisville	View
KRTX Portland, OR	23 mi west-southwest	1,300 ft	Excellent — the lowest scan sees close to the ground
KLGX Langley Hill, WA	118 mi northwest	12,400 ft	Limited — the beam overshoots the lowest part of storms
KATX Seattle/Tacoma, WA	164 mi north	21,100 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.
