Which radars cover Cornwells Heights?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 30 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 Cornwells Heights | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 30 mi east-southeast | 1,800 ft | Excellent — the lowest scan sees close to the ground |
| KDOX Dover AFB, DE | 90 mi south-southwest | 8,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOKX Upton, NY | 123 mi east-northeast | 13,100 ft | Limited — the beam overshoots the lowest part of storms |
