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
Latest medium-range guidance indicates little further amplification of large-scale mid-level troughing across the eastern mid-latitude Pacific, but a broad embedded cyclonic circulation, with a number of shorter wavelength perturbations pivoting around its periphery, may continue to evolve through this coming weekend. These may be accompanied by multiple areas of surface cyclogenesis, including one cyclone with an occluding front which may advance into northern Pacific coastal areas late Saturday night into early Sunday. However, it appears that the coldest mid-level air, supportive of boundary-layer based destabilization conducive to thunderstorms, might remain offshore.
At the same time, downstream amplification of mid-level ridging may continue across the Rockies and Great Plains Saturday into Sunday, with subsequent amplification of troughing east of the Mississippi Valley through areas offshore of the southern Atlantic Seaboard Sunday through Monday. This is likely to be accompanied by cold surface ridging building south-southeastward to the lee of the Rockies, through much of the Gulf Basin, which probably will suppress convective potential through the remainder of the period.
While the environment may be at least conditionally supportive of strong to severe thunderstorm development along a frontal zone across parts of the eastern Gulf Coast into southern Atlantic Coast early this coming weekend, surface frontal wave development across inland areas on Saturday is forecast to remain weak, tending to minimize this potential.
