Officials at Warwick are optimistic that Saturday's high-profile fixture will beat the weather.The National Hunt circuit is due to stage a seven-race card, with the feature Betfred Classic Handicap Chase supported by the Grade Two Neptune Investment Management Novices' Hurdle.Frost covers were deployed on Wednesday and with the forecast snow having so far failed to materialise, clerk of the course Jane Hedley is confident the meeting will go ahead. She said: "It's still raining as we speak and so far this afternoon we've had a total of around 4mm.It's still rain rather than snow, which is good news, and it's due to peter out in the next hour or so. "There is another risk of a wintry shower in the morning, but after that it's due to stay dry and clear. "We've got the covers down and before they were laid the ground was soft, good to soft in places. I'll have a dig around in the morning and see where we are then. "The snow was the first hurdle, hopefully we've negotiated that, the next question is how low temperatures will get.According to the current forecast, we should be OK."
