Which radars cover Winona?
The closest NEXRAD Doppler radar is KSGF (Springfield, MO), about 115 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 Winona | View |
|---|---|---|---|
| KSGF Springfield, MO | 115 mi west | 12,000 ft | Limited — the beam overshoots the lowest part of storms |
| KLSX St. Louis, MO | 122 mi north-northeast | 13,100 ft | Limited — the beam overshoots the lowest part of storms |
| KNQA Memphis, TN | 140 mi southeast | 16,300 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.
