Trainer Tom Hogan would like the rain to stay away from the Knavesmire for his Duke Of York Clipper Logistics Stakes challenger Gordon Lord Byron.
The five-year-old won at the highest level in the Prix de la Foret at Longchamp in October and has since been on his travels, running in Hong Kong and Dubai.
"It's good to get him back on grass again. Hopefully we won't get too much rain. Even though he's won on soft ground he's better on good ground," said County Tipperary-based Hogan.
"It's a tough task. He has to carry his Group One penalty and give weight to most of the field. We are playing with the big boys now. He has a reasonably good draw (four) and there is a fair bit of pace on his side."
The other horse in the line-up burdened with a Group One penalty is Society Rock. He signed off last term with a fifth place behind Maarek at Ascot, just a month after beating Gordon Lord Byron by three-quarters of a length in the Betfred Sprint Cup at Haydock.
Trainer James Fanshawe told www.jamesfanshawe.com: "Society Rock is our flagship horse and he has been going nicely at home. Kieren Fallon came to ride him the other day and he didn't get off and say he would rather ride something else.
"He has a Group One penalty so has to give most of them 5lbs and the good fillies Mince and Tickled Pink 8lbs. We are looking forward to running him."
Jim Goldie is looking forward to running his two speedsters Hawkeyethenoo and Jack Dexter, saying: "A bit of rain would help. I hope it comes early enough to get into the ground. Rain tonight would be fine and good ground would suit them both.
"Hawkeyethenoo is in top form. He ran a nice race at Newmarket and he seems in good order. He's a course and distance winner and he beat Society Rock last time they met (at Ascot). He's got the form, you just need luck in running. I quite like his draw (14). I think the race will develop in that area.
"Jack Dexter won the Cammidge (at Doncaster). He would probably like more cut in the ground but we are running him to see if he handles good ground. If he doesn't, then we might put him away until the back end."
