Trotting Around Rain Chances at the 150th Kentucky Derby

Welcome to May! The month normally boasts severe storms, Mother's Day and later sunsets. This weekend will be the 150th running of the Kentucky Derby at Churchill Downs Saturday evening - and rain could affect things.

A dynamic upper-level low will bring the shot at some storms on Friday to parts of the Ohio River Valley, but models are hinting at a fast moving wave joining the party late Friday night into Saturday. That could meet up with enough moisture to keep scattered showers around northern Kentucky into the first day of the weekend. This is where it could be raining around race-time (below).

The Kentucky Derby says on its website that it's a "rain or shine" event, so no delays are expected. However, the conditions could be a little muddy for the horses when the gates open Saturday at 6:57 PM ET.
