|---|---|
| Location | 32.2800°, -89.9840° · Rankin County |
| Elevation | 607 ft above sea level |

How high can KDGX see?
A radar beam travels in a nearly straight line while the Earth curves away underneath it, so the farther a storm is from KDGX, the higher above the ground the radar is looking. Tornadoes start in the lowest few thousand feet, so storms close to the radar show low-level rotation much better.
| Distance from KDGX | Lowest scan (0.5°) | Next scan (1.5°) |
|---|---|---|
| 10 mi | 500 ft | 1,400 ft |
| 25 mi | 1,500 ft | 3,800 ft |
| 50 mi | 3,600 ft | 8,200 ft |
| 75 mi | 6,300 ft | 13,200 ft |
| 100 mi | 9,600 ft | 18,800 ft |
| 150 mi | 18,200 ft | 32,000 ft |

Severe weather inside KDGX's range
Since 1950, NOAA has recorded 1,025 tornadoes within 60 miles of the KDGX radar, 239 of them rated EF2/F2 or stronger. They have been most common in April and March. The strongest was an F5 on March 3, 1966, which passed about 7 miles north-northwest of the radar and caused 58 deaths. The most recent was an EF0 on November 25, 2025, which touched down about 36 miles west of the radar.
Hail: 1,491 reports of hail 1 inch or larger within 60 miles of the KDGX radar since 1955, 127 of them 2 inches or larger. The largest was 4.50-inch hail (grapefruit size) on April 14, 1996.

KDGX radar FAQ
How often does KDGX update?
Every NEXRAD radar completes a full scan about every 4–6 minutes in storm mode, and repeats the lowest tilt more often (SAILS) during severe weather. TALON loads each new scan as it arrives.
What is the range of KDGX?
Reflectivity reaches about 290 miles and velocity about 185 miles, but useful low-level detail is within roughly 100 miles — see the table above.
Is KDGX down?
Radars occasionally go offline for maintenance. When one does, TALON's US radar map fills the gap from neighboring radars (KHDC, KLIX, KGWX).
