You are looking at an outlook that is part of the medium range forecast (the outlook for days 4-8). The most important thing to note is that lack of a risk does not mean zero risk. Generally speaking, confidence has to be pretty high for the Storm Prediction Center to have an outlook area this far into the future.
When no specific risk areas are shown, you might see one of these phrases:

DISCUSSION
Severe weather potential will persist through the remainder of the work week and into parts of the weekend as an amplified upper wave and attendant surface low traverse the country. The cold front associated with the late-week storm system will most likely push south into the Gulf by Sunday as high pressure builds across the eastern two-thirds of the country and short-wave ridging builds aloft. This will likely limit the potential for widespread severe thunderstorms for the early portion of next week.
D4/Friday - Lower Missouri Valley into the southern Plains
The approach of an upper wave into the central U.S. will support steady intensification of a surface low across eastern KS and into the lower MO River Valley through the day Friday. This will support a northward flux of low to mid 60s dewpoints through the day, which should yield SBCAPE values on the order of 2000 to perhaps 3000 J/kg across northern OK into eastern KS and far western MO by late afternoon based on a consensus of model solutions. Thunderstorm development is expected as a cold front slowly begins to push southeast and overtakes a surface trough/dryline. Deep-layer shear vectors and storm motions off the boundary should promote initially discrete cells, though upscale growth is anticipated by the evening hours amid persistent ascent along the front. Regardless, long-range guidance has shown a consistent signal for a robust convective environment over the past 48 hours, and the favorable alignment of both deterministic and ensemble guidance lends high confidence in a severe threat emerging across this region Friday afternoon and evening.
D5/Saturday - Midwest/OH Valley
Friday's surface low will continue to deepen as it accelerates northeastward into the Midwest and Great Lakes by late Saturday. Northward moisture advection is expected ahead of a trailing cold front as it rapidly shifts east across the Midwest and lower OH Valley through the afternoon. Strong flow fields within the lowest few kilometers and focused lift along the front will likely support some degree of a severe wind threat. However, guidance continues to show disagreement regarding mean wind vector orientation with the front and the degree of pre-frontal destabilization, both of which will influence the intensity of convection and the overall severe threat.
