Yesterday only the southwestern part of the Miami Valley was under a marginal risk for severe weather. That risk has now been shifted north by the SPC to include just about the entire Miami Valley. A marginal risk for severe weather is on the lower end of the severe weather scale. If we see any thunderstorm Sunday, a few could be on the borderline of becoming strong to severe.
If you heading somewhere Sunday morning showers and possible storms will move into the area late Sunday morning. Those showers and possible storms will continue into the afternoon and evening where thunderstorms could become more widespread. Steady to heavy rain is possible and remember some storms could be on the borderline of becoming strong to severe. Thunderstorm activity will taper off around 6 PM. We will still have to deal with lingering showers through the evening though.
The energy for the development of thunderstorms will kind of be in place tomorrow. Our CAPE values in the afternoon tomorrow will be close to 1000 J/Kg. So while this is not high on the scale, there is a little energy there. We could also see clouds break tomorrow allowing in the sunshine. That sunshine could add a little instability in the atmosphere making the threat for storms greater.
