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 continues to indicate the evolution of an increasingly prominent mid/upper high across the lower Colorado Valley and Plateau late this week into next weekend. It appears likely that this will continue expanding and encompassing a significant portion of the interior U.S. by early next week, as an evolving larger-scale trough begins to dig across and southeast of Hudson Bay. While there appears relatively small spread within and among the various model output concerning this larger-scale evolution, there is considerable spread concerning the migration of one particularly notable short wave trough around the periphery of the ridge.
Of particular concern, it appears probable that a plume of very warm elevated mixed-layer air will advect along the southern fringe of a belt of intensifying flow around the northern through northeastern periphery of the mid/upper ridge. As it does, coupled with low-level moistening, this type of regime could support the periodic evolution of organizing clusters, potentially including one or two potentially long-lived, accompanied by swaths of damaging surface gusts.
It appears that this could focus anywhere from near and north of the central Canadian/U.S. border vicinity through the Great Lakes into the Northeast by early next week. However, due to lingering uncertainty with the synoptic developments, and the generally low predictability of these mesoscale systems, in this type of regime at this extended range, severe probabilities still appear less than 15 percent. However, depending on model trends, this could change in later outlooks for this period.
