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
Severe thunderstorm potential appears low during the Day 4-8/Tue-Sat period. An upper shortwave trough will traverse the northern Plains and Upper Midwest on Tuesday and Wednesday. As this occurs, a low-amplitude and weak mid/upper flow regime will overspread much of the central/southern Plains toward the eastern U.S. Strong surface high pressure over the East and prior cold frontal passages across parts of the Plains will result in only modest boundary layer moisture beneath the progressive mid-week upper shortwave trough.
Later in the period, upper troughing will deepen across the western U.S. Meanwhile, an amplifying upper ridge is expected across the East, resulting in broad southwesterly mid/upper flow across the Plains. Some modest moisture return could occur across the Plains within the southwesterly flow regime, but any deep moisture is forecast to remain confined across TX and the Gulf Coast. While periods of thunderstorms are possible late in the period across the Plains, overall severe potential is likely to remain limited due to a lack of focused large scale ascent and a modest thermodynamic environment.
