Which radars cover Dayton?

The closest NEXRAD Doppler radar is KPDT (Pendleton, OR), about 60 miles 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 Dayton	View
KPDT Pendleton, OR	60 mi southwest	4,600 ft	Good — most storms and steady rain or snow show clearly
KOTX Spokane, WA	96 mi north	9,000 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMSX Missoula, MT	196 mi east-northeast	28,200 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.
