We'll be back from 10:15 BST tomorrow to see whether Surrey and Rory Burns can edge even closer to being crowned champions.
There are seven other matches entering day three, with a result looming in at Lord's in the Middlesex-Kent game.
Division One
Division Two
Surrey 213-6, Worcestershire 336
All over for day two at New Road. Surrey, with skipper Rory Burns still there on 103, trail Worcestershire by 123 runs with four wickets remaining.
With 56 of their initial 110-over allocation gone, it now looks unlikely that they will reach maximum batting bonus points in that time.
Should they go on past 400 (and do it within the 110 overs tomorrow), now Somerset have lost, Surrey can seal their first County Championship title since 2002 before this game is over. But it looks more likely that they will have to either draw or win here to do so. And they still need a further 123 to overhaul the Pears' first-innings total.
Bottom-of-the-table Worcestershire, don't forget, are the only Division One side Surrey haven't beaten in the Championship this season.
The two sides drew at The Oval in April - and to do at last that again would be a proud achievement for the Pears as they look to survive the drop.
Durham 220-4, lead Sussex by 201

It was chaos here this morning with 13 wickets falling by lunch. Ollie Robinson's 'five-for' helped to dismiss Durham for just 103 in their first innings. It lasted 31.3 overs. Their fourth shortest.
But Chris Rushworth then took 8-51 in 13 overs as Sussex were bowled out for just 122. Their 25.2 overs was one of their shortest innings too.
So we then went from the chaos to the calm. Cameron Steel put on 72 with Alex Lees for the first wicket in Durham's second innings as the batsmen gave the impression they were suddenly playing in a different town.
Steel battled on to reach his first 100 of the season, adding 55 for the fourth wicket with Michael Richardson, who offered assistance for an hour and 18 minutes before falling for 19.
Durham's lead passes the 200 mark and the game has turned on its head once again.
Surrey 211-6, Worcestershire 336
Image source, Getty ImagesA fourth County Championship century of the summer for Surrey skipper Rory Burns.
He brings up his ton with a boundary off home captain Daryl Mitchell, who is on with his dibbly-dobblies as the light is bad - too bad to keep the Worcestershire seamers on.
Two overs left. The first of them from spinner Ben Twohig.
Notts 177 & 116-1 v Essex 233
Notts nightwatchman Luke Fletcher is dropped at first slip in the final over by Murali Vijay, so he survives along with Kraigg Brathwaite (47*).
Essex constantly complain about the condition of the ball but the umpires have none of it.
It sums up a frustrating day for the visitors, with Notts closing on 116-1 with a lead of 60 runs.
T Curran c Whiteley b Tongue 0 (Surrey 204-6, Worcestershire 336)
Four balls later, the Pears get another wicket. Ross Whiteley is the catcher this time as Tom Curran is caught off paceman Josh Tongue.
But there are now concerns about the light.
Clarke c Milton b Whiteley 33 (Surrey 203-5, Worcestershire 336)
Worcestershire get another breakthrough as occasional spinner Ross Whiteley gets a rare wicket.
He gets one to leap and Rikki Clarke gloves it to be caught behind for 33, to end a 68-run stand with skipper Rory Burns.
Yorkshire 209 & 127-3, Lancashire 252
Definitely Yorkshire's day in the Roses match.
A day that began with Lancashire on 105-0 has turned on its head a bit.
The Tykes now lead Lancs by 84 runs with seven wickets remaining.
Jack Brooks was the hero in the morning session with 5-66, but the final session belonged to Gary Ballance and Tom Kohler-Cadmore, with an unbroken century fourth-wicket stand.
Surrey 199-4, Worcestershire 336
Rory Burns is now on 97 as he homes in a century at New Road.
The England opener has now shared a second half-century partnership with Rikki Clarke, having earlier put on 97 with Ollie Pope.
Notts 177 & 115-1 v Essex 233
Three overs left in the day at Trent Bridge with nightwatchman Luke Fletcher on 5 and Kraigg Brathwaite still on 47, waiting for his half-century.
Notts are 115-1 in their second innings with a lead of 59 runs over Essex.
Cameron Steel has made a century for Durham against Sussex, reaching 102 off 160 balls with 13 fours.
He escaped on 95 when Phil Salt slipped over and missed a catch. Durham are 194-4 in their second innings, leading by 175 runs.
Kent need 66 runs to win at Lord's against Middlesex. They're 90-4 with Heino Kuhn (21*) and Daniel Bell-Drummond (20*) building a potentially match-winning partnership.
Jack Taylor will be 97* overnight for Gloucestershire with play ending at Glamorgan. Gloucestershire are 283-6 in reply to the hosts' measly 137.
I'll remind you that Northants-Derbyshire and Leicestershire-Warwickshire are also done for day two.
Leicestershire 100, Warwickshire 384-9
It's over for the day due to bad light in Leicester at an intriguing moment - with Division Two leaders Warwickshire's last pair in - and 16 needed in the next two overs to earn a fifth batting bonus point.
But it's quite a last pair. England all-rounder Chris Woakes on 64. And Bears captain Jeetan Patel, probably the best last man in cricket history.
That should make for an entertaining first two overs first thing tomorrow.
Slater lbw Coles 54 (Notts 108-1, lead by 52 runs)
Image source, Rex FeaturesEssex have their long-awaited breakthrough.
Matt Coles traps Ben Slater LBW for 54, with Notts 108-1.
Luke Fletcher comes in as nightwatchman with five overs left in the day to join Kraigg Brathwaite, who's on 47.
Notts 177 & 103-0 v Essex 233
Kraigg Brathwaite's sixth boundary takes him to 43 and Notts to 103-0.
He and Ben Slater seem well on their way to building a score similar to their effort at Yorkshire last week.
Essex haven't come close to dismissing either of the openers.

Notts 177 & 99-0 v Essex 233
Ben Slater is the first Notts opener to reach 50, reaching the milestone with an outside edge.
He raises his bat to the balcony at Trent Bridge - it took 83 balls and contained nine fours.
Notts are 99-0 with Kraigg Brathwaite on 39, leading Essex by 43 runs
Yorkshire 209 & 93-3, Lancashire 252
The 50 partnership comes up for Gary Ballance and Tom Kohler-Cadmore in the Roses match at Headingley.
Ballance is now moving well on 39, with first-innings centurion TKC on 24. With seven second-innings wickets in hand, Yorkshire now lead by 50 in a game that, if they win, will probably end up relegating Lancashire.
Kent are struggling at Lord's against Middlesex - they're 57-4 and need 99 more runs to win. Heino Kuhn and Daniel Bell-Drummond are at the crease for Kent.
Warwickshire have just lost Sam Hain for 72 but remain in cruise control on 344-6 against Leicestershire, who were all out for 100. Chris Woakes is still there on 36, chasing a potential fifth batting point.
Cameron Steel (93*) is closing in on a century for Durham, who are 178-3 in their second innings against Sussex. They have a lead of 159 with seven wickets in hand.
Jack Taylor is even closer to his ton - he's on 97 against Glamorgan at Sophia Gardens, with Gloucestershire 283-6 having added 142 runs for the seventh wicket. They already have a first-innings lead of 146.
Jacks b Twohig 17 (Surrey 135-4, Worcestershire 336)
Will Jacks goes, bowled by Ben Twohig. Only the second wicket to spin in the match.
And a welcome break for the hosts after the loss of South African paceman Wayne Parnell.
After taking three wickets in 12 overs, he has left the field after splitting the webbing on his right hand. Not good news ahead of this Saturday's first T20 Blast finals day for the already injury-hit Pears.
Notts 177 & 80-0 v Essex 233
Image source, Rex FeaturesWe have 16 overs left in the day at Trent Bridge, with Essex in a spot of bother.
Notts are 80-0 with Kraigg Brathwaite (35*) and Ben Slater (42*) creeping towards half-centuries.
The hosts lead by 24 runs.
