Which radars cover Mountain House?

The closest NEXRAD Doppler radar is KMUX (San Francisco, CA), about 47 miles south-southwest. 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 Mountain House	View
KMUX San Francisco, CA	47 mi south-southwest	3,200 ft	Good — most storms and steady rain or snow show clearly
KDAX Sacramento, CA	51 mi north	3,700 ft	Good — most storms and steady rain or snow show clearly
KBBX Beale AFB, CA	120 mi north	12,700 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.
