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
D4/Monday will feature conditionally favorable strong low to mid-level flow along/ahead of a cold front moving east across the Southeast. The intense eastern Great Lakes/southeast ON cyclone should occlude as a secondary cyclone forms along coastal ME into the Canadian Maritimes. Guidance is fairly consistent for this time frame with indications of minimal instability along the trailing portion of the cold front, as well as diminishing large-scale ascent/convective signal through the day. Severe thunderstorm wind probabilities appear at or below 5 percent.
The continental airmass spreading across the Gulf in the wake of the frontal passage should yield minimal severe potential mid-week. Towards late week, return flow will support airmass modification along the western Gulf Coast. The EC-AIFS hints at a low-amplitude shortwave impulse in the D8/Friday time frame, which could support a return to non-negligible severe potential.
