Which radars cover Petersburg?
The closest NEXRAD Doppler radar is KDTX (Detroit, MI), about 57 miles north-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 Petersburg | View |
|---|---|---|---|
| KDTX Detroit, MI | 57 mi north-northeast | 4,200 ft | Good — most storms and steady rain or snow show clearly |
| KCLE Cleveland, OH | 101 mi east-southeast | 9,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIWX Fort Wayne, IN | 109 mi west-southwest | 11,000 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.
