A spell of hot weather is usually broken by storms and we are expecting plenty of them during Friday's racing. Perhaps Luke's selection can help you afford a new brolly with some left over for good waterproofs.
Here's a quick snapshot of Luke's tips, click on the horse's name to have a punt with Planet Sport Bet.
2.20 Chester - Rickenbacker
The 2.20 at Chester is a seven furlong nursery, a competitive one as well as you would expect for a nursery at this time of year.
There are plenty of chances, the likes of Truly Acclaimed comes into this race in okay form, Sir Min as well shouldn't be too far away. But there is another one I prefer, hopefully at a bit of a price as well.
Rickenbacker is that one who last time round I didn't think ran that too badly at Epsom. Throw out any performance of a hold up horse on that occasion, if you backed a front runner on that day at Epsom you likely bagged a winner.
There was a massive bias towards the pace angle and Rickenbacker missed the break a touch. He was towards the back of the field, stayed onto good effect finishing back in fourth. This was in one of the earlier races as well but we didn't know much about the pace bias.
So Rickenbacker can be upgraded massively for that run. Tom Dascombe obviously does very well round here at Chester.
Kieran Schofield taking the ride and a further five pounds off, I think that's a positive, and coming from stall five as well, he should be able to clear the field and try and get towards the forward.
He has got good form here at Chester as well in the past, finishing second a few runs ago, was fifth in a pretty good race after that. So I think everything is in the favour of Rickenbacker.
A competitive race, but hopefully one for Tom Dascombe.
3.45 Doncaster - Raatea
At the 3.45 at Doncaster, much like the majority of the week, is an absolute cracker. A handicap over six and a half third furlongs - a one where we have a tonne of chances.
The likes of Able Kane has been in good form recently, was third in Newmarket a couple of starts ago, was a good second last time round as well for Rod Millman who had largely been in form for the majority of the season, should go close one set again.
But I don't think we'll be able to overturn form with Raatea who a horse I'd liked for a while, he was a nice horse for Marcus Tregoning, has now switched for the Julie Camacho yard, and hes been very good this season.
He made a decent start to life for Julie Camacho finishing in fourth at Newcastle, then went a little bit in and out but last time was brilliant at Newmarket.
There was a stand side rail bias but you have to be prominent on that. He was on the stand side rail but towards the back of the field. Had to come off of it later on in the day and ended up delivering his challenge towards the middle of the track. He's gone up five pounds for that effort.
Raatea, for all he is tricky, I do think he is pretty classy. And with a mark of 89, he can do it once again.
4.45 Salisbury - Codify
The final selection comes courtesy of the 4.45 at Salisbury, and a nursery just shy of seven furlongs, and one that brings into the race a whole host of interesting horses. A few that were exciting at the start of their career and a couple since then haven't gone the same way.
A few we have already seen in nursery contests and running pretty well. Blue Collar Lad fits the bill for that statement, was second at the Qatar Goodwood Festival in a valuable contest but didn't back that up last time around at Newmarket.
There were excuses, he was pretty well fancied as well but I do think Blue Collar Lad will have to step up a fair bit on that effort, but we know he is capable.
I think Codify will be the selection, who on debut was behind was behind Gisburn - a fair effort, a bit of an eye catcher as well back in third at Newbury.
You thought after that he was an already made winner but he went onto Salisbury and he managed to lead, he faded a touch late on, and then Windsor last time round was a disaster.
Yes he got forward once again, but he was from stall 10 which wasn't ideal whatsoever - a horrible draw at Windsor, especially for a young horse set. He again got a little tired in the closing stages.
This looks a little more ready made for Codify. He goes into nursery company off the mark of 75. I think that is workable and Hector Crouch is in good form as well, so hopefully he can get another winner on board.
