Surrey lead by 61 against Warwickshire after reaching 211-8 at stumps.
Wes Agar takes 4-60 as Kent bowl out Middlesex for 229 at Lord's.
England's Rehan Ahmed makes 90 for Leicestershire against Glamorgan
Seam bowler Timm van der Gugten takes 6-88 for Glamorgan
Durham enforce follow-on against Derbyshire with a lead of 287.
Sussex's Cheteshwar Pujara 99 not out at close of play against Gloucestershire.
Warwicks 145-9 v Surrey
Dan Mousley comes down the track and flicks Dan Worrall away into the leg-side but picks out Ryan Patel, the lone man in the deep, who atones for dropping him on 16 on day one.
No addition to his overnight score by the left-hander, who faced 132 balls and hit eight fours.
Oliver Hannon-Dalby is Warwickshire's number 11.
Warwicks 145-8 v Surrey
Chris Rushworth collects the first runs of the day at Edgbaston, pushing a ball from Kemar Roach down the ground for two.
Wonder if the former Durham seamer is fancying his chances when it's his turn to bowl for Warwickshire in these conditions.
Was that a dropped catch off his own bowling? We rather think it was. Roach's fourth wicket will have to wait.
Warwicks 143-8 v Surrey
Looks like Dan Mousley believes attack is the best form of defence. He is looking to play his shots but one whistles just past the edge as Dan Worrall starts with a maiden.
"Showers throughout the afternoon," says BBC Coventry & Warwickshire's Clive Eakin. We hope he was talking about somewhere else.
Leics 329-5 v Glam
Shiny new ball taken by Glamorgan.
But Timm van der Gugten immediately overpitches and Pete Handscomb drives him down the ground for four.
Another Australian, Michael Neser, is back as well to try and break the partnership.
But he's also driven straight past his bootlaces by Handscomb!
Warwicks 143-8 v Surrey
So, how long can the 2021 champions prolong their first innings against the 2022 champions? We are about to find out.
Jordan Clark took two wickets with successive balls in the final over of day one and one more will give Surrey a full complement of bowling points.
It's Dan to Dan to start up - Worrall bowling to Mousley, who is 55 not out. Nothing to do with Dan Dan from Carry On Screaming.
Durham 410-8 v Derbys
Successful inspection at the Riverside and they'll be underway shortly.
Leics 305-5 v Glam
A second batting point on the board for the Foxes.
Still 30 overs to go in the bonus point period.
Leics 298-5 v Glam
Fourth innings for Pete Handscomb this season and a third time past 50.
98 balls for this effort with four fours - including two this morning off Andrew Salter.
A slog sweep beat deep square to the fence and a cut through points brings him a half-century.
Middlesex v Kent 152-6
Grant Stewart is a big strong man. He flicks his wrists at a delivery from Ethan Bamber and clips him away over the deep square leg boundary for six. Very similar to yesterday's antics.
Think that signifies what the gameplan might be for the visitors. The 150 is up. These two can punish anything loose, so Middlesex have brought on Tim Murtagh to try and outfox them.
Middlesex v Kent 145-7
Image source, Rex FeaturesAnd his average goes down...
Ethan Bamber produces a decent bouncer which draws the left-handed Ben Compton into a swat on the spin but he cn only edge to John Simpson who clutches the ball to his right.
A priceless knock for his side, again. Matt Quinn joins Grant Stewart, what will their gameplan be?
Leics 283-5 v Glam
Andrew Salter's off spin into the attack at Grace Road.
Last ball of the over, Rehan Ahmed is down the pitch to lift over mid-on for four.
Australian Peter Handscomb is at the other end on 40 but rather playing second violin to the 18-year-old.
The pair have a hundred partnership in 154 balls and Leicestershire are back on top.
Middlesex v Kent 139-6
Another immaculate contribution from Ben Compton. What a revalation he has been for Kent, and the county game.
He brings up his 10th first-class 50 with a streaky edge for four from the 165th ball he has faced. Unfashionable? Perhaps. Unflappable? Definitely.
This unbeaten 52 has not yet improved his first-class or season average.
Warwicks 143-8 v Surrey - start delayed
The umpires have taken a look in Birmingham and play will commence at mid-day, with lunch to be taken at 1:45. It is hoped that, barring any further unwelcome weather, 88 overs will be possible before the close.
Glos v Sussex 47-1
The umpires want to give the outfield a bit more time at Nevil Road so they'll check again in just over an hour.
An early lunch will also be taken, which sounds like good news.
But the Bristol outfield has taken a battering in the past two months so don't count your chickens just yet.
Middlesex v Kent 133-6
Grant Stewart rattles Tom Helm through the covers with gusto to begin his latest over.
Helm replies in superb fashion, beating the bat a couple of times and getting the Italian international to play inside the line before an overthrow from Ethan Bamber after a sharp single rolls all the way to the rope.
10 off the over, after all that.
Middlesex v Kent 123-6
You're probably still in the middle of elevenses, but the Lord's floodlights have just flickered into life as there is blanket of cloud over St John's Wood. Hopefully nothing to worry about at this stage.
Ethan Bamber and Tom Helm operating from either end early on day two. Just 10 runs from the opening five overs. Kent won't mind that one jot.
Leics 255-5 v Glam
Image source, Rex FeaturesRehan Ahmed adds a third boundary of the opening 13 minutes and goes to his half-century.
It's a slightly strange swatty pull through mid-on but he has fifty in 70 balls.
Leics 250-5 v Glam
Two-thirds of a day yesterday at Grace Road but they're away on time and Leicestershire have brought up a batting point.
Rehan Ahmed punched Timm van ger Gugten through the covers for four fifth ball of the day.
He tried again in the Flying Dutchman's next over and edged wide of second slip for four more before a leg bye raised the 250.
Middlesex v Kent 121-6
Ben Compton is off and running with a boundary off Ethan Bamber's first over of the morning at Lord's. He moves onto 44.
There are a LOT of children enjoying a morning out at the grand old ground today. Do you remember the constant backgrund hum of vuvuzelas at the FIFA World Cup in South Africa? Well this is very similar.
When bat hits ball the high-pitched noise intensifies to something more akin to what I'd imagine a Taylor Swift concert is like.
Just another weekday morning on the county circuit...
As always, we'd love to hear from you during the course of the day's play if you have any pithy, or indeed trenchant, observations about your team. Tweet us at #bbccricket.
