How high can KPDT see?
A radar beam travels in a nearly straight line while the Earth curves away underneath it, so the farther a storm is from KPDT, 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 KPDT | 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 KPDT's range
Since 1950, NOAA has recorded 24 tornadoes within 60 miles of the KPDT radar, 1 of them rated EF2/F2 or stronger. They have been most common in May and June. The strongest was an F2 on June 26, 1958, which touched down about 26 miles north of the radar. The most recent was an EF0 on March 5, 2024, which touched down about 24 miles east-northeast of the radar.
Hail: 144 reports of hail 1 inch or larger within 60 miles of the KPDT radar since 1955, 9 of them 2 inches or larger. The largest was 2.75-inch hail (baseball size) on July 9, 1995.

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