Which radars cover Tempe?
The closest NEXRAD Doppler radar is KIWA (Phoenix, AZ), about 17 miles east-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 Tempe | View |
|---|---|---|---|
| KIWA Phoenix, AZ | 17 mi east-southeast | 900 ft | Excellent — the lowest scan sees close to the ground |
| KFSX Flagstaff, AZ | 92 mi north-northeast | 8,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KEMX Tucson, AZ | 128 mi southeast | 14,100 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.
