Which radars cover Petersburg?

The closest NEXRAD Doppler radar is KHTX (Huntsville, AL), about 41 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 Petersburg	View
KHTX Huntsville, AL	41 mi southeast	2,800 ft	Excellent — the lowest scan sees close to the ground
KOHX Nashville, TN	64 mi north	5,000 ft	Good — most storms and steady rain or snow show clearly
KHPX Fort Campbell, KY	105 mi north-northwest	10,300 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.
