  1. Prospects poor

    Heavy rain overnight and this morning mean the start of the second day will almost certainly be delayed.

    The local forecast says it may turn to showers later, so a later start to the day may mean some cricket later.

    Worcestershire will be frustrated having had by far the better of the opening day.

  2. Stumps - day one

    So, at almost 10pm, the first day of day-night County Championship fixtures is at an end.

    We'll be taking a closer look at how things unfolded, with plenty of analysis, on the BBC Sport website shortly, so keep your eyes peeled for that.

    I'll be back with Felix Keith tomorrow at 13:45 BST to bring you all the action from day two.

    Sleep well!

    Scott: It's even weirder watching the county cricket updates two hours ahead in Rhodes.

  5. Stumps at Cardiff

    Glamorgan 5-0 v Derbyshire 288

    Glamorgan nightwatchman Timm van der Gugten and conventional opener Jacques Rudolph have seen off the two overs without any drama.

    Earlier, Derbyshire did well to make 288, with Tom Milnes' 53 and Tony Palladino's 23 boosting their total. Interesting second day ahead.

  6. Stumps at Edgbaston

    Warwickshire 23-1 v Lancashire 273

    That's also your lot at Edgbaston.

    Jonathan Trott and Andrew Umeed have seen things through to stumps for the hosts after Will Porterfield went in James Anderson's second over.

    The Bears still have plenty of hard work to do with the bat to make sure they stay in the game though.

  7. Close of play at Durham

    Durham 197 v Worcestershire 210-4

    Worcestershire close day one in a strong position after skittling Durham for less than 200 and then moving into the lead late on.

    The Pears have dished out some serious punishment, scoring at almost five an over.

    Brett D'Oliveira (91 not out) will resume with Moeen Ali (36 not out) in the morning.

  8. Pink ball verdict

    Essex spinner Simon Harmer thinks he got more bounce and drift from the pink ball...

  9. Post update

    There is County Championship cricket still going on at 9.44pm folks.

    Anyone else feel a bit odd?

  10. Stumps at Trent Bridge

    Nottinghamshire 135-3 v Kent 180

    Another strong day for Division Two's leaders Nottinghamshire.

    Kent are currently third and will be hot on their heels for promotion, but have been out-played on day one, with only Daniel Bell-Drummond's unbeaten 84 really putting up much of a fight to the hosts' bowling.

    To complete things, Steven Mullaney finishes 63 not out alongside Alex Hales (28 not out). Notts are just 45 runs behind with seven first-innings wickets in-hand.

  11. Kevin in a dark place

    Essex 106-0 v Middlesex 246 - stumps

    You really couldn't make it up. It's been a long and now very dark day for BBC London's Kevin Hand...

  12. Derbyshire bowled out for 288

    Glamorgan v Derbyshire 288

    I was just getting ready for bed and then Derbyshire decided to lose their last wicket.

    Tony Palladino skied Michael Hogan to Graham Wagg at mid-off for 23.

    It means Glamorgan have got to come out and bat for two overs tonight.

  13. Stumps at Wantage Road

    Northants 261 v Leicestershire 65-4

    It's over at Northampton too, where Leicestershire will be relieved to get off the pitch four down. Nightwatchman number two, Clint McKay, did his job alongside Colin Ackermann.

    Northants' day, after Ben Duckett's marvelous century and Max Holden's 92.

  14. Night arrives at Chelmsford

    Essex 106-0 v Middlesex 246 - stumps

    It's darkish at Chelmsford now...

  15. Stumps at Hove

    Sussex 358-9d v Gloucestershire 31-0

    Sussex skipper Ben Brown declared to leave Gloucestershire a task and they've duly seen it through, with openers Cameron Bancroft (18 not out) and Chris Dent (7 not out) unbeaten.

    They're 327 runs behind going into day two at Hove.

  16. Post update

    Warwickshire 11-1 v Lancashire 273

    Warwickshire aren't going to take any risks this evening.

    They're 11-0 off eight overs.

    Five overs to survive, James Anderson is into his fifth over.

  17. Stumps at Chelmsford

    Essex 106-0 v Middlesex 246

    Chelmsford sunset

    It's been another stellar day for Division One leaders Essex and their march towards a first County Championship title in 25 years.

    After Simon Harmer took five wickets to bowl Middlesex out for less than 250, Alastair Cook and Nick Browne batted throughout the final session.

    Essex trail by 140 with plenty of batting to come.

  18. Close of play at Hampshire

    Hampshire 211-9 dec v Somerset 18-0

    No such batting woes for Somerset at the Ageas Bowl as they reach stumps unscathed.

    Marcus Trescothick and 20-year-old debutant Ed Byrom saw out the remaining six overs after Hampshire declared.

    The forecast for the next couple of days in Southampton isn't looking great I'm afraid, but we'll keep our fingers crossed.

  19. WICKET Porterfield (lbw b Anderson) 1

    Warwickshire 3-1 v Lancashire 273

    BBC Sport's Stephan Shemilt said Jimmy would fancy this - and there's his first wicket.

    The seamer spears one into the pads of Will Porterfield and he's on his bike.

    Warwickshire's batting woes of 2017 continue.

  20. Stumps at Headingley

    Yorkshire v Surrey 374-6

    Kumar Sangakkara

    Yorkshire and Surrey, you win the medal for ending closest to the scheduled 9pm finish!

    And it's been a very good day for the visitors, with fifties for Jason Roy and Kumar Sangakkara leading them towards maximum batting bonus points.

    Plenty of hard work to do for Yorkshire - but they've got some talent in their batting line-up - Joe Root and Jonny Bairstow are okay aren't they?
