A boundary of sorts looks to set up in the area outlined. It does appear that instability will be high in the highlighted area, giving storms a very well developed breeding ground. A sharp lake breeze from Lake Michigan in a southwest direction may very well feed into this instability and ignite some intense thunderstorms. A wind field that will be going opposite directions on different sides of this boundary is making me concerned for some rotation. However, considering that the major shearing and upper level wind dynamics are farther north, tornadoes will not be a huge concern.
In southwest Texas, another boundary may ignite some intense storms. This would likely be along a traditional dry line, which would incite the potential for some rotation. That remains to be seen in the long term.
