Which radars cover Dunnigan?

The closest NEXRAD Doppler radar is KDAX (Sacramento, CA), about 31 miles south-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 Dunnigan	View
KDAX Sacramento, CA	31 mi south-southeast	1,900 ft	Excellent — the lowest scan sees close to the ground
KBBX Beale AFB, CA	46 mi north-northeast	3,100 ft	Good — most storms and steady rain or snow show clearly
KMUX San Francisco, CA	120 mi south	12,800 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.
