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
An expansive area of high pressure will build across the eastern CONUS on D4/Sunday and push a frontal zone near the Gulf Coast. After this, ridging will build across the central CONUS and allow rich moisture to advance well inland from the southern Plains to the Midwest by D7/Wednesday. However, building heights aloft will result in minimal if any forcing for thunderstorm development during this period. Even beyond day 7, model guidance shows decent agreement in a modest ridge breakdown without much severe weather concern.
