After looking at the Evening Weather Data, quite a growing concern for much of SUNDAY.
I do think there will be Several Waves of Moisture slugging across the Corridor. What I will be showing through the Blog is the RPM Run from the WSI Vortex ModelLab I acquire with my work here in Wyoming.
I think for the EARLY-Mid Morning Hours on Sunday, our 1st wave of Moisture and Showers could slide in. This will be the Warm Front; increasing our Dewpoints. However, some could be strong and a few showers could contain some Small Hail with them.
< A plume of showers by early Sunday will slide in from the West and thunder/lightning is possible with Heavy Rain.
< By Late Morning/Early Afternoon, another Round of Showers could push through. Some could be Heavy, but each wave sends in More Moisture from the Southwest/South.
** LOOK out toward Central Illinois. Individual Cells (supercelluar) could form and start rotating along the strong wind field this storm is being accompanied by.
MID Afternoon is the Critical Time Frame for many! IF We stay cloudy and cool/stable and depending on how long these showers last could determine what type of Severe Weather the Corridor could see. More breaks in the clouds increases the wind field, increases the moisture and temperature.
WHAT the RPM Model is showing are Breaks in the Clouds after the late Morning activity erodes away. This adds our Instability... = NOT GOOD.
Likely see Temperatures climb nearing 70° for much of the Corridor and in the Low to Mid 60°s for Dewpoints from Louisville and points South toward the KY/TN state Line.
Last Blog, I spoke of the Wind Field and wind speeds halfway up in the Atmosphere at 500mb's. Well last post I showed the Wind Field over 100-120mph near Indy. Well, it has Shifted farther SOUTH. Now its just North of Louisville in Southern IN. This could be a growing concern for much of Southern IN/ and much of KY along the 65 Corridor.
<< So much dynamics with this Storm, but it will be a Blustery Day for sure enhancing our Damaging Wind Threat. The turning of winds with height & direction (SHEAR) is possible to enhance Tornadoes. 
<< THIS is Something you may not want to see. Isolated Supercell Storms are possible from Southern IN and down towards Bowling Green area early Evening. It was looking a like line of storms, but that could no longer be the case.
* THIS shows the Tornado Threat increasing since I showed you that "Clearing" of the Skies that could happen early Afternoon before the skies turn sour.
<< NAM Model Run this evening shows the Signif. Tornado Parameter for Sunday late Afternoon-Early Evening.
Very High for this time of the Year and anyone in the Yellow yields caution. Orange/Red along the Corridor is poses an ominous feeling
THOUGHTS: The Newest SPC Outlook will come out little later this Evening and I will stay up and see what they think of for our Storm Risk and Threat. After looking at tonight's data and especially the Upper Air Wind Charts, I am concerned. Threats of Strong Damaging Winds and Isol'd Tornadoes are a Possibility, BUT knowing who will receive it is finding a needle in a haystack. It could occur but we don't know when and where yet.
