Which radars cover Laplace?

The closest NEXRAD Doppler radar is KHDC (Hammond, LA), about 31 miles north. 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.

KHDC
Hammond, LA		31 mi north1,900 ftExcellent — the lowest scan sees close to the ground
KLIX

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