Ed Barnard survives the hat-trick ball, but it's a devastating spell before lunch from Joe Mennie.

The Aussie paceman has 3-20.

Simon Smale: Best out-ground for me was Southchurch Park, Southend for Essex - lots of history (Bradman's Invincibles played there & were bowled out inside a day for the only time on tour - albeit for 721!) Lost its appeal when it moved out to Garons Park.

I know it well Simon, I played my club cricket for Old Southendians there back in the day!

Oliver Hannon-Dalby has given Warwickshire the edge against Kent at Tunbridge Wells with two wickets in his first spell. The home side are 79-4, with Heino Kuhn (39) and Zak Crawley (0) both out lbw.

Sussex are moving into a promising position against Durham at Arundel, where young guns Philip Salt and Tom Haines have steered their side to 109-1 after the early wicket of Luke Wells.

Leicestershire are 52-2 against Middlesex at Grace Road, after a wicket each for Tim Murtagh and Steven Finn. Mark Cosgrove is playing in his 200th first-class match today and is joined in the middle by Colin Ackermann.

We're still waiting to get underway at Swansea, where rain is delaying play between Glamorgan and Derbyshire.

A reminder that Northants v Gloucestershire is a day-night match, due to start at 13:30 BST.

Looks a bit of a damp wicket there Andy. It's a bowl first sort of day...

The Somerset bowlers have been past the edge plenty of times, but still have nothing to show for it.

Rory Burns and Arun Harinath continue to frustrate the Division One leaders, with Harinath 11 away from a half-century.

The visitors turn to a bit of spin from Dom Bess at Guildford.

A good recovery from Sussex at an overcast Arundel, who having been asked to bat lost Luke Wells for just eight, with the score on 9-1.

However, two young Sussex players Phil Salt (aged 21) and Tom Haines (19) have led the recovery, with their 50 partnership coming up in just 11 overs.

Leicestershire are resuming their innings at Grace Road, where Mark Cosgrove is playing his 200th first-class match, after a rain delay of half an hour this morning. They are 33-2 against Middlesex.

Kent are 62-2 against Warwickshire at Tunbridge Wells, where the in-form Heino Kuhn is unbeaten on 35.

Sussex have recovered after the early wicket of Luke Wells and are now 73-1 against Durham at Arundel.

Rain has ended any chance of play at Swansea before lunch, where Glamorgan are hosting Derbyshire.

Northamptonshire play Gloucestershire at 13:30 BST at Northampton.

Notts have two highly experienced batsmen in the middle in Chris Nash and Samit Patel.

The duo have more than 11,500 first-class runs each and are making batting look relatively easy.

The typically attacking Nash is up to 34 off 47 balls, Patel is on 19.

Worcestershire captain Brett D'Oliveira is in at five after that Joe Clarke wicket.

D'Oliveira was named Pears skipper for at least the next three County Championship games after Joe Leach was ruled out for the rest of the season.

They'll need a big knock from Dolly today.

Your favourite outgrounds...

Lord Andrew Dennett: Tunbridge Wells. Remember as a kid my brother and I being taken by our parents (Sussex and Middlesex supporters) along with a full picnic and bat and ball to play on the outfield! Glorious!!

Worcestershire are recovering nicely after the loss of those two early wickets.

Daryl Mitchell has even joined the boundary game, cutting Tom Bailey to the point rope.

Joe Clarke is settling in nicely on 17 at the other end.

Lancashire have just made their first bowling change - Aussie seamer Joe Mennie replaces Bailey.

Josh Davey is out of the attack after Arun Harinath swatted him for six.

Captain Tom Abell comes on - Somerset need a wicket.

The forecast in Southampton is pretty decent for the day-night game as well.

Anyway, back to the cricket...

While the batsmen continue to tick along, I've just had a look at the weather forecast for the next few days in our three Division One matches currently in progress.

Not too bad...

Middlesex are being held up by a rain delay at Grace Road, where earlier this morning Leicestershire's Harry Dearden hit Steven Finn straight to Hilton Cartwright at point to leave the home side on 25-2.

Philip Salt and Tom Haines have steered Sussex to 52-1 against Durham after the early loss of Luke Wells at Arundel.

At Tunbridge Wells Kent are 41-2. Heino Kuhn is at the crease with his captain Joe Denly after an early wicket apiece for Warwickshire's Keith Barker and Chris Wright.

Rain continues to delay play between Glamorgan and Derbyshire at Swansea.

Northamptonshire play Gloucestershire later on in a day-night match at Northampton, due to start at 13:30 BST.
