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
Modified return flow will slowly build across the western Gulf mid to late week, with a maritime tropical airmass probably reaching parts of the TX Gulf Coast next weekend. As mentioned by WPC's EPD, run-to-run model variability remains high with a large amount of spread in the potential evolution of a broad upper trough approaching the West Coast on D5/Thursday. This is well illustrated by the change in SPC-CSU GEFS-ML probabilistic guidance over the past 24 hours for D7/Saturday – from a mesoscale 5% area in the Mid-MS Valley in yesterday's D8 to a full-latitude 5% from the Rio Grande to the Great Lakes, along with broad 15% and 30% highlights from parts of TX/LA to the Mid-MS Valley. While its parent 00Z GFS appears conducive to severe, over what would likely be a subset of these large highlights, this latest run lacks any semblance of continuity. In addition, other models, such as the EC-AIFS suggest a closed, cutoff low may just be in the process of moving onshore on D7/Saturday, compared to the progressive, full-latitude trough over the Great Plains in this GFS run. For this forecast, will upgrade to Predictability Too Low for D7/Saturday and extend into D8/Sunday for indications of possible severe, probably focused in the South-Central States, within a low predictability pattern.
