Which radars cover Philadelphia?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 97 miles 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 Philadelphia | View |
|---|---|---|---|
| KLSX St. Louis, MO | 97 mi southeast | 9,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 129 mi east | 14,300 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 137 mi north-northeast | 15,700 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.

KLSX (St. Louis, MO), about 97 miles southeast. KILX (Lincoln, IL) is 129 miles away and also covers the area.
Does radar show snow in Philadelphia?
Yes. TALON colors snow blue, a rain–snow mix pink and freezing rain purple using NOAA's precipitation-type analysis. Over Philadelphia the lowest scan from KLSX is about 9,100 ft up, so light snow from shallow clouds can be under-shown — check NWS winter alerts too.
