Which radars cover St. Clair?
The closest NEXRAD Doppler radar is KDTX (Detroit, MI), about 50 miles west. 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 St. Clair | View |
|---|---|---|---|
| KDTX Detroit, MI | 50 mi west | 3,600 ft | Good — most storms and steady rain or snow show clearly |
| KCLE Cleveland, OH | 103 mi south-southeast | 10,000 ft | Limited — the beam overshoots the lowest part of storms |
| KGRR Grand Rapids, MI | 155 mi west | 19,100 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.
