Which radars cover Ayer?

The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 48 miles south-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 Ayer	View
KBOX Boston, MA	48 mi south-southeast	3,300 ft	Good — most storms and steady rain or snow show clearly
KGYX Portland, ME	114 mi northeast	11,700 ft	Limited — the beam overshoots the lowest part of storms
KENX Albany, NY	126 mi west	13,800 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.
