All eyes on the sky as the countdown to the Kentucky Derby is on. One day left and the forecast is looking promising for the horses that will perform best on a dry track. Clouds will be lingering today as a system passes over the Great Lakes and that will keep temperatures in the 60s. But with clearing skies tomorrow, highs will jump into the mid 70s with winds coming out of the west at 15 mph. Sunshine will persist through the afternoon with just a few clouds heading into the evening.
What will this mean for tomorrow’s race? From The Bleacher Report, “For the race, the clear outlook is good news for California Chrome and the other top contenders. The trainers of the best horses in any given race want to take away as many variables as possible, with weather being one of the most important. That’s especially true when it comes to a massive field like the Kentucky Derby. When the horses race in the slop, falling behind early becomes an even bigger disadvantage because all of the mud gets kicked right into the trailing pack’s faces.”
Rain isn’t an all that uncommon of an occurrence on the day of the race and as shown in the statistics below, it rains 47% of the time, which, of course plays a huge role in the outcome of the race.
