Which radars cover Simi Valley?

The closest NEXRAD Doppler radar is KVTX (Los Angeles, CA), about 27 miles west-northwest. 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 Simi Valley	View
KVTX Los Angeles, CA	27 mi west-northwest	1,600 ft	Excellent — the lowest scan sees close to the ground
KSOX Santa Ana Mountains, CA	71 mi east-southeast	5,800 ft	Good — most storms and steady rain or snow show clearly
KEYX Edwards AFB, CA	89 mi northeast	8,000 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.
