| Severe weather expected on Tuesday. All hazards are possible. |
| Dry conditions continue for the middle Ohio Valley today and tonight, while showers and thunderstorms are possible in and near the central Appalachians this afternoon and tonight. A potent system for Midsummer has the potential to bring impactful severe weather to the area Tuesday. Damaging winds, hail, and a tornado or two will be possible, in addition to heavy rain. Timing for severe storms currently appears to be Tuesday afternoon and evening in at least two rounds. Flash flooding is also a concern with heavy rainfall from thunderstorms, especially where heavy rainfall is most persistent or repetitive. Drier and cooler weather arrives Wednesday through Friday, with additional storm chances forecast this weekend. Get additional details in our Area Forecast Discussion... |

| 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.
