I'm no weather expert, but because you've got a regular pattern around the radar (the circle) that really shouldn't appear in a normal weather condition, the beam may be getting grounded due to local conditions - see beam ducting.

The lil notch on the right is looks like it might be showing incomplete, conflicting, or out of bounds data. The site's map legend may have a decoder for that pattern.
