7:15 Nowcast:

Here is my new Nowcast update. There are three areas of concern, the biggest one outlined in the white oval, where instability is very high and shear is also high. This is where big tornadoes could occur. These will shift east in AR this evening and will bring a tornado threat for most of the state, although once they get towards NE AR they may weaken some due to less instability. In TX it looks like things are trying to fire but I think activity along the dry line will be more isolated.
