Which radars cover Foristell?

The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 17 miles east-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 Foristell	View
KLSX St. Louis, MO	17 mi east-southeast	900 ft	Excellent — the lowest scan sees close to the ground
KILX Lincoln, IL	127 mi northeast	13,800 ft	Limited — the beam overshoots the lowest part of storms
KPAH Paducah, KY	170 mi southeast	22,200 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.
