Which radars cover St. Johns?

The closest NEXRAD Doppler radar is KGRR (Grand Rapids, MI), about 51 miles west. 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 St. Johns	View
KGRR Grand Rapids, MI	51 mi west	3,600 ft	Good — most storms and steady rain or snow show clearly
KDTX Detroit, MI	59 mi east-southeast	4,400 ft	Good — most storms and steady rain or snow show clearly
KIWX Fort Wayne, IN	128 mi south-southwest	14,000 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.
