Which radars cover Petros?

The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 59 miles east. 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 Petros	View
KMRX Knoxville, TN	59 mi east	4,400 ft	Good — most storms and steady rain or snow show clearly
KOHX Nashville, TN	118 mi west	12,400 ft	Limited — the beam overshoots the lowest part of storms
KJKL Jackson, KY	121 mi north-northeast	12,800 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.
