DISCUSSION
KEY MESSAGE 1)
Quiet conditions remain in place with ridging and surface high pressure in control to bring near average temperatures today. On Wednesday, a weak surface low will be found to the southeast. Mid level vorticity will be found alongside it in the afternoon as a weak upper low tracks north through eastern Kentucky. This will bring showers and some thunderstorms, generally expected over the se CWA but more likely in the eastern Scioto River Valley. Adjusted pops to be capped at chance, which was a quite minor change.

By Thursday, a larger trough to our west will move into the area and drag a long, trailing cold front across the Great Lakes region. This frontal boundary looks to stall out just west of our CWA, providing the focus for showers and thunderstorms from Thursday through the weekend. Details still need to be worked out regarding how things will progress, but based on the orientation of the front and large scale flow, training thunderstorms could introduce a flooding threat.
