The front promised earlier in the week has begun to sag into northern Kentucky this evening moving slower than originally forecast. This front will not bring much in the way of relief as we continue to see a persistent ridge of high pressure aloft. The hot and humid near 90 degree days looks to continue into the weekend. Saturday, we will begin to see this high pressure ridge finally begin to sink back southwest and a return of near 80 temperatures possible into next week. A few shower and storm chances into the weekend as a few weak upper level disturbances move in Saturday night into Sunday. Without any strong atmospheric forcing, it is hard to say any significant activity will develop. With the ridge moving slightly southwest, areas to the east will have the best chance as they are on the edge of the retrograding ridge.

Looking into the weekend, the high heat index values of 100 could be possible. Outdoor activities should be done with caution remaining well hydrated. Saturday night/Sunday could produce some thunderstorm development. A few of these may be strong with the best chances to the east. Storms should be scattered in nature.
