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
A dry, continental airmass will persist across most of the CONUS for the first part of next week. Severe weather chances will start to increase by the middle of the week and into the later part of the week. Forecast guidance consistently shows mid 60s F dewpoints across the Plains and into the Midwest. However, aloft the pattern remains quite uncertain. The ECMWF and the GEFS and EPS all show a developing large-scale trough centered across the western CONUS with multiple shortwave troughs which could result in severe weather Day6/Wed to Day 8/Fri. However, the 00Z GFS and the EC-AIFS show a consolidated mid-level trough which could result in a much more substantial severe weather event across the central/southern Plains. At this time, uncertainty is too high for specific risk areas, but Day6/Wed to Day 8/Fri will likely feature multiple days of severe weather across portions of the central/southern Plains.
