LEXINGTON, Ky. (WKYT) - Father’s Day will be muggy ahead of tonight’s heavy rain. Flash flooding is possible late tonight into early Monday morning. Today is not only Father’s Day but also the first day of astrological summer, and it will feel like it. Afternoon highs will be in the upper 80s, and it will be humid. There will be a light southwest breeze that will pick up speed in the evening. We’ve had clear skies to start the day, but it will be cloudy by the late afternoon.
