For Italy, I found this list of differente radar sites (EU, Swiss, Italian), but I have no idea how to access the data http://www.astrogeo.va.it/radar/radar.php one of these is the Government page http://www.protezionecivile.gov.it/jcms/it/mappa_radar.wp
For Northern Italy we have also this http://www.centrometeolombardo.com/radar/ but again no idea on how to access source
