How high can KLGX see?
A radar beam travels in a nearly straight line while the Earth curves away underneath it, so the farther a storm is from KLGX, 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 KLGX | 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 |
Height of the beam's center above the radar, using standard refraction. Terrain can raise or block the beam.
Severe weather inside KLGX's range
Since 1950, NOAA has recorded 8 tornadoes within 60 miles of the KLGX radar, all of them weak (EF0–EF1). They have been most common in December and October. The strongest was an EF1 on October 18, 2019, which touched down about 56 miles east-northeast of the radar. The most recent was an EF0 on March 19, 2021, which touched down about 55 miles south of the radar.
Hail: 3 reports of hail 1 inch or larger within 60 miles of the KLGX radar since 1955. The largest was 1.25-inch hail (half dollar size) on November 23, 2014.

KLGX radar FAQ
How often does KLGX 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 KLGX?
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 KLGX down?
Radars occasionally go offline for maintenance. When one does, TALON's US radar map fills the gap from neighboring radars (KATX, KRTX, KPDT).
