Which radars cover Vacaville?

The closest NEXRAD Doppler radar is KDAX (Sacramento, CA), about 19 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 Vacaville	View
KDAX Sacramento, CA	19 mi east-northeast	1,000 ft	Excellent — the lowest scan sees close to the ground
KBBX Beale AFB, CA	81 mi north-northeast	7,000 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMUX San Francisco, CA	83 mi south	7,300 ft	Fair — the beam can pass over shallow snow and low-level rotation

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
