Increase severe wording for Saturday. && .KEY MESSAGES... 1) Severe weather and flooding possible on Saturday, lower potential for Sunday. 2) Off and on thunderstorm chances through the week. && .DISCUSSION... KEY MESSAGE 1) Dry conditions will continue the remainder of the day today. Showers and isolated thunderstorms will move into the region overnight and through the morning daytime hours. The more concerning time period for severe weather and flooding potential will be during the afternoon and evening hours on Saturday as a low pressure system nears the area. There is decent instability and low level shear. LCLs are also expected to be low. While the threat is conditional, there is the potential for a few short lived tornadoes to occur in this environment. The greatest threat area for tornadoes will be eastern Indiana, portions of northern Kentucky and into southwest Ohio. Another potential threat will be damaging winds, however the DCAPE environment is not overly impressive. The greatest threat area for flooding will also be the same area as tornadoes. While moisture propagation vectors indicate that storms will be moving, there is the potential for multiple rounds of storms in the same area. Will continue to highlight the severe threat and flooding in the HWO and other messaging platforms. There will be additional thunderstorm on Sunday. Widespread showers and some thunderstorms are expected on Sunday. The greater severe threat will be east of the area, however cannot rule out a strong to severe storm. In addition, localized heavy rain and flooding will be possible. KEY MESSAGE 2) Off and on thunderstorm chances will continue into next week. There is still uncertainty in the upper low. There are varying solutions with some showing the low being more progressive while others show the low meandering near the area and keeping thunderstorm chances longer around the region. There is more confidence and a lean to keep precipitation chances around longer into the week. After this system does move out of the area there will still be the potential for another system to work into the area later in the week. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
