Which radars cover Porterville?

The closest NEXRAD Doppler radar is KHNX (San Joaquin Valley, CA), about 38 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 Porterville	View
KHNX San Joaquin Valley, CA	38 mi west-northwest	2,400 ft	Excellent — the lowest scan sees close to the ground
KEYX Edwards AFB, CA	106 mi southeast	10,500 ft	Limited — the beam overshoots the lowest part of storms
KVBX Vandenberg AFB, CA	114 mi southwest	11,800 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.
