Which radars cover Dennis?

The closest NEXRAD Doppler radar is KGWX (Columbus AFB, MS), about 46 miles south. 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 Dennis	View
KGWX Columbus AFB, MS	46 mi south	3,200 ft	Good — most storms and steady rain or snow show clearly
KNQA Memphis, TN	108 mi west-northwest	10,800 ft	Limited — the beam overshoots the lowest part of storms
KHTX Huntsville, AL	125 mi east-northeast	13,500 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.
