Which radars cover Newark?

The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 113 miles 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 Newark	View
KLSX St. Louis, MO	113 mi southeast	11,600 ft	Limited — the beam overshoots the lowest part of storms
KDVN Quad Cities, IA	133 mi north-northeast	15,000 ft	Limited — the beam overshoots the lowest part of storms
KILX Lincoln, IL	140 mi east	16,200 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.
