Which radars cover Grand Coulee?

The closest NEXRAD Doppler radar is KOTX (Spokane, WA), about 66 miles east-southeast. 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 Grand Coulee	View
KOTX Spokane, WA	66 mi east-southeast	5,300 ft	Good — most storms and steady rain or snow show clearly
KPDT Pendleton, OR	156 mi south	19,300 ft	Limited — the beam overshoots the lowest part of storms
KATX Seattle/Tacoma, WA	162 mi west	20,700 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.
