Anyone want to try to guess any 'snow inflated predictions' for the morning assuming there are ~25 to 27m watching TV tonight? I'll go for:
BBC One
16:30 - Six Nations Rugby: 6.6m (34.0%)
18:55 - BBC News: 4.1m (17.1%)
19:15 - The Magicians: 4.9m (19.4%)
20:30 - Lottery: 5.5m (21.0%)
20:40 - Casualty: 6.3m (25.0%)
21:30 - Mrs Brown's Boys: 5.0m (20.0%)
ITV1
18:15 - You've Been Framed!: 3.9m (17.0%)
19:15 - Harry Hill's TV Burp: 5.7m (22.8%)
19:45 - Take Me Out: 5.9m (23.0%)
21:00 - The Jonathan Ross Show: 4.2m (17.0%)
22:00 - The Talent Show Story: 2.3m (10.0%)
+1 approx 0.2m to 0.4m added onto all the above for ITV1.
As I said earlier, I think ITV will be the main beneficiary, because their shows go towards the younger skewing audience who are normally out (myself excluded

) on Saturday nights.
But in reality I expect BBC One and ITV1 to have a big boost tonight.
