Which radars cover Massena?

The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 64 miles east-northeast. 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 Massena	View
KDMX Des Moines, IA	64 mi east-northeast	4,900 ft	Good — most storms and steady rain or snow show clearly
KOAX Omaha, NE	83 mi west	7,300 ft	Fair — the beam can pass over shallow snow and low-level rotation
KEAX Kansas City, MO	171 mi south	22,400 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.
