Which radars cover Cohasset?

The closest NEXRAD Doppler radar is KBBX (Beale AFB, CA), about 29 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 Cohasset	View
KBBX Beale AFB, CA	29 mi south-southeast	1,700 ft	Excellent — the lowest scan sees close to the ground
KDAX Sacramento, CA	97 mi south	9,200 ft	Fair — the beam can pass over shallow snow and low-level rotation
KRGX Reno, NV	122 mi east	13,000 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.
