Forecast for the Kentucky Derby remains on track with steady light rain showers over Churchill Downs. In 138 years the Kentucky Derby has never been canceled due to weather. You can check out Kentucky Derby weather history via the National Weather Service in Louisville, Ky.
Steady showers will continue to stream in from the south for the remainder of the afternoon and into the evening. All of this rain is part of a much larger storm system centered over Missouri and Arkansas. Louisville and Churchill Downs is on the far eastern edge of this rain, and these rain showers are not expected to end before the start of the Kentucky Derby. Post time for the Derby is at 6:24 p.m. ET and I fully expect the light steady rain to be occurring.
