How high can KTLH see?
A radar beam travels in a nearly straight line while the Earth curves away underneath it, so the farther a storm is from KTLH, 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 KTLH | 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 KTLH's range
Since 1950, NOAA has recorded 366 tornadoes within 60 miles of the KTLH radar, 71 of them rated EF2/F2 or stronger. They have been most common in April and March. The strongest was an F3 on February 13, 2000, which passed about 53 miles north of the radar and caused 11 deaths. The most recent was an EF1 on April 7, 2025, which passed about 40 miles north-northeast of the radar.
Hail: 316 reports of hail 1 inch or larger within 60 miles of the KTLH radar since 1955, 22 of them 2 inches or larger. The largest was 4.00-inch hail (softball size) on January 28, 1995.

KTLH radar FAQ
How often does KTLH 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 KTLH?
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 KTLH down?
Radars occasionally go offline for maintenance. When one does, TALON's US radar map fills the gap from neighboring radars (KVAX, KEVX, KEOX).
