Which radars cover Grain Valley?
The closest NEXRAD Doppler radar is KEAX (Kansas City, MO), about 14 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 Grain Valley | View |
|---|---|---|---|
| KEAX Kansas City, MO | 14 mi south | 800 ft | Excellent — the lowest scan sees close to the ground |
| KTWX Topeka, KS | 108 mi west | 10,800 ft | Limited — the beam overshoots the lowest part of storms |
| KSGF Springfield, MO | 131 mi south-southeast | 14,600 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.
