Showers and storms will become more widely scattered as the day progresses. Any of the storms that develop could produce some decent rainfall. When you factor in the rounds of moderate and occasionally heavy rainfall during the overnight, we could see some solid totals from this system.
It's a slow moving frontal boundary that is bringing the rain. That keeps a scattered chance of rain alive through Sunday. Especially, during the afternoon and evening. It might be a good one to take mom to a special breakfast or brunch.. because we know she deserves the very best.
The front will not move all the way through Kentucky. It will stall out Sunday night and into Monday morning before surging toward the north. This will allow a big push of warmer air to take over again. Highs climb into the mid 80s early next week. The frontal boundary will then race across Kentucky on Tuesday. It has the potential to trigger some stronger storms.
The airmass behind the front will bring some much cooler air. You'll see daytime highs drop from the 80s into the 60s. Those cooler temps will linger for a few days. This isn't unusual to see cool air like this during May.
Try to enjoy your soggy Saturday!
