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
At the start of the forecast period, the mid-level pattern will generally be zonal across much country, with the greatest height gradient found across the northern United States. By the middle of next week, a short-wave trough moving within the broader flow regime will amplify the height field across the northern Rockies before moving into the central US. The overall pattern recognition would suggest the potential for at least isolated severe thunderstorms ahead of this feature across then northern Plains into the Upper Great Lakes. However, model run-to-run timing differences along with inter-model timing differences precludes the ability to identify 15% unconditional probabilities on any given day.
Associated with the aforementioned mid-level trough, a surface-cold front will push south through much of the Plains and into the East. Additional thunderstorms will be likely along the front, however, the location of the front on any given day will be strongly influenced by previous days' convection. As such, when coupled with the uncertainty in the timing of any mid-level wave, predictability is too low to identify unconditional probabilities at this time.
