Which radars cover Folsom?

The closest NEXRAD Doppler radar is KHDC (Hammond, LA), about 15 miles west-southwest. 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 Folsom	View
KHDC Hammond, LA	15 mi west-southwest	800 ft	Excellent — the lowest scan sees close to the ground
KLIX New Orleans, LA	30 mi southeast	1,800 ft	Excellent — the lowest scan sees close to the ground
KDGX Jackson, MS	115 mi north	11,800 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.
