A plume of moisture coming out of the Gulf will combine with a slow-moving cold front to provide the ingredients for an extended period of moderate to at times heavy rainfall today and tonight. By this time tomorrow morning, we could see some 2-3 inch rainfall totals across south central Kentucky. The steadyness of the rain should allow the grounds to soak it in well, limiting the flood potential.
Another system will move into the region later Wednesday afternoon and night. The exact track of this system could bring additional heavy rains over that area that is receiving heavy rains today and tonight. The second graphic shows rainfall totals expected right now from Wednesday to Wednesday night. As you can see, areas along and south of a Bowling Green to Danville line have the best chance for that overlap of heavy rains from the two waves…possibly seeing some spots with over 4 inches of rain. That much rain can lead to localized flooding…so be prepared for flood messaging with your partners over the next couple of days.
