Which radars cover Griggsville?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 70 miles south. 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 Griggsville | View |
|---|---|---|---|
| KLSX St. Louis, MO | 70 mi south | 5,600 ft | Good — most storms and steady rain or snow show clearly |
| KILX Lincoln, IL | 80 mi east-northeast | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 132 mi north | 14,800 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.
