| An unsettled Memorial Day weekend on tap amid a pesky front. |
| Rain associated with a low pressure system and an associated warm front could be heavy at times, especially given any thunderstorm activity through this evening, or just embedded locally heavier downpours. Localized flooding could occur, particularly in locations impacted by heavy rain over the last several days. A Flood Watch remains in effect for northeast Kentucky, far western West Virginia, and southeast Ohio into Saturday morning. Additional rounds of showers are likely each day of the Memorial Day holiday weekend, with mainly afternoon and evening thunderstorms also possible. Temperatures will recover to near or a few degrees above normal beginning Saturday. Unsettled weather looks to continue for the start of the new work week as well, but may finally start to settle down later in the week, as high pressure builds surface and aloft to the northwest of the Ohio Valley.

| Flash Flood Guidance |
Flash Flood Guidance (FFG) provides a general indication of the amount of rainfall evenly distributed over various durations (in hours), necessary to cause small streams to overflow their natural banks. During heavy rainfall, accurate interpretation of the guidance consists of the combination of rainfall that has already occurred plus any additional rainfall that can be confidently expected to fall over the same location in the immediate future.
It should be noted that FFG values represent estimates of average soil moisture and stream flow conditions. Flooding may occur with less rainfall than indicated in areas of high rainfall intensities, impervious surfaces, or steep slopes.
