Post update
Nottinghamshire (267 & 286-5) need 110 more runs to beat Durham (330 & 332-4 dec)
Right - 13 overs still to bowl in theory.
Notts need 110 more to win, Durham need five wickets.
But.....there's some nasty looking clouds on the horizon which could scupper either of those two scenarios.

How much longer will this one between Nottinghamshire and Durham continue though?
