Which radars cover Castine?

The closest NEXRAD Doppler radar is KGYX (Portland, ME), about 80 miles west-southwest. 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 Castine	View
KGYX Portland, ME	80 mi west-southwest	6,900 ft	Fair — the beam can pass over shallow snow and low-level rotation
KCBW Caribou, ME	124 mi north-northeast	13,300 ft	Limited — the beam overshoots the lowest part of storms
KBOX Boston, MA	205 mi southwest	30,600 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.
