I'm on GRLevel3 looking at the KDVN area. The radar was in VCP 32 (clear air mode) and switched to VCP 12 (precip mode) to track the developing weak convection to the west. As the radar went into precip mode, the MS river began to produce organized ground clutter. Basically you can see the state border between Iowa and Illinois made up of radar echoes along the river. What exactly is causing this?
It shows up pretty good here too: http://radar.weather.gov/radar.php?rid=dvn&product=N0R&overlay=11101111&loop=no
