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
Medium-range model output suggests that amplified large-scale troughing, initially centered near the Pacific coast at the outset of the period, will gradually develop eastward, across and east of the Rockies during the latter half of the week into next weekend. It appears that this will occur in generally piecemeal fashion, as a series of smaller-scale/lower amplitude perturbations. However, given the presence of an initially seasonably warm environment to the lee of the Rockies, potential exists for periodic lee surface cyclogenesis, possible strong.
To this point, guidance has exhibited rather poor predictability with these features, but there does appear at least somewhat greater certainty in potential for substantive surface cyclogenesis by Thursday, across the central Great Plains toward the Great Lakes region. Even so, it still appears that preceding Gulf boundary-layer moistening and inland return flow will only support limited moistening within the developing warm sector across the middle Mississippi Valley through much of the day Thursday. By Thursday night, there are indications that a modest late moisture surge into the lower Ohio Valley could contribute to increasing convective potential, but the extent of the severe threat remains unclear at this time.
Guidance still indicates that better low-level moisture return may commence ahead of the cold front trailing the cyclone, across parts of the Ohio/Tennessee Valleys through Ark-La-Tex and southern Great Plains Friday into Saturday, as upstream perturbations begin to emerge from the West. However, current model output suggests that renewed cyclogenesis may be more subdued, and it is possible that convection may tend to develop and train along and to the cool side of the front and/or outflow, with uncertain severe weather potential.
