Which radars cover St. Peter?
The closest NEXRAD Doppler radar is KVWX (Evansville, IN), about 74 miles 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 St. Peter | View |
|---|---|---|---|
| KVWX Evansville, IN | 74 mi southeast | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 92 mi north-northwest | 8,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 99 mi west | 9,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
