Nottinghamshire v Somerset 231-4
Four more for Archie Vaughan as he drives at one outside off and takes a thick edge... but it runs harmlessly through the gully area and away to the boundary.
Durham 218-4 v Derbys
Martin Andersson is short of a length and Ollie Robinson has loads of time to pull it away for four.
The new ball can't come soon enough for Derbyshire, who are toiling out there at the moment.
Nottinghamshire v Somerset 227-4
Archie Vaughan has really dug in since coming in at six and nudges a single off Brett Hutton to go to 18 from 87 balls.
Somerset are in touching distance of a bonus batting point now, with just 23 more needed to get there.
Sussex 106-1 v Glamorgan 155
"It's got really gloomy," says BBC Sussex's Adrian Harms.
The umpires have looked at each other as if to say 'what do you reckon?' - and a few moments later, they lead the players off.
Leics v Essex 233-3
Image source, ShutterstockMatt Critchley's looked relatively becalmed recently, but he dabs Ben Green away to third man to bring up his half-century - the fourth time he's passed 50 this season.
Critchley gets there from 81 balls and he and Jordan Cox will be looking to stretch Essex's total towards a commanding position tonight. They still have more than 20 overs to face this evening, weather and light conditions permitting.
Yorkshire 327-4 v Warwickshire
The dismissal of Matthew Revis hasn't slowed Yorkshire down.
Captain Johnny Bairstow is looking to play his shots while Will Luxton continues to add to his career best, reaching 148.
Milnes c Bailey b Livingstone 22 (Lancashire v Kent 163-9)
Matt Milnes has tried to get on with it for Kent... but it's failed here.
Milnes attempts to go big against Liam Livingstone over mid-on but holes out to Tom Bailey on the rope.
Livingstone now has 4-10 in this seven-over spell. Not bad after five years away from the County Championship format for Lancashire.
Lancashire v Kent 159-8
Matt Milnes is trying to tack on what might be valuable runs for Kent at the end of this innings.
He picks up a boundary off George Balderson, before a single apiece for himself and Matt Parkinson, before Milnes pulls one for three through mid-wicket.
Durham 206-4 v Derbys
It's taken a while because of that rain interruption but Graham Clark cuts Martin Andersson away for a single as he and Ollie Robinson post a 50 stand from 121 balls.
McSweeney c Bracey b Clarke 117 (Northants 353-5 v Glos)
And the new ball does bring dividends for Gloucestershire and Kristian Clarke!
Nathan McSweeney tries to glide one off his pads and just gets a faint edge around the corner, with James Bracey moving to his left to gather the catch.
Clarke has his third wicket and George Bartlett is the new man in for Northamptonshire.
Zafar lbw Allison 2 (Middx 220-7 v Worcs)
Ben Allison strikes with the new ball to claim his third wicket.
Zafar Gohar offers no stroke to one which nips back at him. It's a misjudgement and he's gone having taking 24 balls to score two.
Middlesex have now lost four wickets for 21.
Nottinghamshire v Somerset 222-4
No surprises there.
Since taking three wickets for 47 runs in the first 18 overs, Notts have taken just one wicket for 175 runs in the 62 overs since then.
Haseeb Hameed's side take the new ball and it's Fergus O'Neill who will get first dibs.
Lancashire v Kent 150-8
Kent reach 150 but this has been a real disappointment with the bat for the visitors.
Sussex 102-1 v Glamorgan 155
Tom Alsop drives Tom Norton for four, the first boundary of his innings, as Sussex reach three figures, with 19 overs to come after this one.
Nottinghamshire v Somerset 222-4
And there is the 50 partnership for Jordan Hermann and Archie Vaughan.
Hermann has contributed to 38 of those.
Northants 352-4 v Glos
James Sales is at full stretch to reach this widish delivery from Kristian Clarke, but makes enough of a connection to steer the ball for a boundary that takes Northamptonshire past 350.
Three bonus points in the bag and, with more than 27 overs left until the cut-off point in this innings, the home side must surely be eyeing the chance of picking up a fourth and fifth.
Durham 204-4 v Derbys
They are back out in the middle at the Riverside.
A single is the only addition so far.
Nottinghamshire v Somerset 218-4
Image source, ShutterstockJordan Hermann is only with Somerset on a three-game deal in the County Championship but he's hit a first century for the club here.
After scoring 25 in his first match against Sussex, the South African has delivered a vital innings for his side against the defending champions at Trent Bridge.
Hermann brings it up in classy style, timing a perfect straight drive to punch it down the ground for four off Lyndon James.
Sussex 97-1 v Glamorgan 155
The downfall of Tom Haines has brought Tom Alsop to the middle for his first Championship innings of the season and he is quickly under way with a couple.
Daniel Hughes is 37 not out at the other end.
Dudgeon st Moores b Livingstone 3 (Lancashire v Kent 146-8)
Oh dear.
Keith Dudgeon dances down the track to Liam Livingstone but completely misses it down the legside and Joe Moores does very well to bring it in and whip off the bails for a stumping.
What a return this is proving to be for Livingstone for the first time in the Championship in five years.
He has figures of 3-5 in this current spell - and 3-39 from 14 overs overall.
Lancashire are skittling through Kent now. Six wickets taken for 35 runs since tea.
