Take a look at the expected CAPE values per the HIRES NAM model. To make it simple, the higher the number, the more likely it is for your area to receive thunderstorms. Once you begin to get into the deeper oranges and beyond, those are impressive numbers for this area, especially for the areas it is suggesting to be in the 3,000 to 4,000 j/kg range.
The image above is valid for late Sunday Afternoon/Early Evening. The corresponding simulated radar looks like this...
Notice how it is not a solid line of storms that forms, that is to be expected as this will not be a solid line of storms. It will be a broken line, hit or miss, type storms. But, the areas that do receive these storm cells have the potential of seeing a wicked storm. As this line heads southeast, the line will become stronger and there won't be as many gaps in the radar, and is why I put the southeast areas on my map in the greatest threat area.
Timing: Sunday Noon through 9 PM Sunday Night
Impacts: Torrential Rain, Large Hail, Gusty winds 60mph<, Isolated Tornadoes
