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
Upper troughing over the Interior West, containing multiple smaller impulses, will gradually progress eastward to the Plains states through the middle of the week (Days 5-7/Tuesday-Thursday) before another mid-level trough approaches the central U.S. by next weekend. Deterministic medium-range guidance consensus depicts the development of a surface low over the southern Plains around Day 6/Wednesday, accompanied by seasonal low-level moisture return. However, guidance also depicts a poor overlap of vertical wind shear with the moist axis, likely inhibiting greater severe potential, in agreement with calibrated ML/AI guidance consensus. As such, no probabilities were introduced this outlook.
