Which radars cover Nampa?

The closest NEXRAD Doppler radar is KCBX (Boise, ID), about 18 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 Nampa	View
KCBX Boise, ID	18 mi east-southeast	1,000 ft	Excellent — the lowest scan sees close to the ground
KPDT Pendleton, OR	184 mi northwest	25,400 ft	Limited — the beam overshoots the lowest part of storms
KLRX Elko, NV	197 mi south	28,500 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.
