Looks very strange! 25/06/2013
Not a conflict of temperatures (storms could cause radar interference)
Clearly located where the pressures are the lowest (hence a lot of rain)
I wonder… Either the radars are all malfunctioning and not detecting correctly, but why would the two over the alps behave that way, there’s no excessive rain there…
The other way to cause mis-detections is, interferences with something else…
