Which radars cover Arivaca?

The closest NEXRAD Doppler radar is KEMX (Tucson, AZ), about 45 miles east-northeast. 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 Arivaca	View
KEMX Tucson, AZ	45 mi east-northeast	3,100 ft	Good — most storms and steady rain or snow show clearly
KIWA Phoenix, AZ	120 mi north	12,800 ft	Limited — the beam overshoots the lowest part of storms
KYUX Yuma, AZ	207 mi west-northwest	31,000 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.
