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
Wednesday/Day 4 to Thursday/Day 5
An upper-level ridge will move into the Rockies on Wednesday, as northwesterly mid-level flow remains from the Great Plains to the eastern U.S. On Thursday, the ridge will become less amplified as it moves into the Great Plains. At the surface, low-level moisture is forecast to return northward into the lower to mid Mississippi Valley. Within this moist airmass, a pocket of moderate instability is expected by late Thursday afternoon. Thunderstorm development will be possible near a front along the northern edge of the stronger instability from northeast Missouri east-northeastward into north-central Ohio. Storms are expected to move east-southeastward across the Ohio Valley on Thursday afternoon and evening. A severe threat will be possible, but the magnitude of any potential threat is still uncertain.
Friday/Day 6 and Sunday/Day 8
From Friday into Saturday, a cold front is forecast to move southward from the mid Mississippi Valley to the central Gulf Coast. Isolated thunderstorms will be possible along parts of the front both Friday and Saturday afternoon. Weak instability should keep any severe threat marginal.
On Sunday, the models are forecasting a dry airmass over most of the continental U.S., suggesting the potential for storms is low.
