Hayley here - Do you want to see severe weather in your calendar?
* it's like an add-on for your digital calendar NOT a paper calendar
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
An upper low is forecast to be located over the Great Basin on Friday/D4, moving into the northern Rockies/High Plains through Saturday/D5, and weakening all the while. Models indicate 500 mb winds by Saturday will only be in the 20-25 kt range with this feature. Therefore, despite low 60s F dewpoints, the severe risk is expected to be somewhat disorganized. However, at least low probabilities may be required in later outlook updates. Meanwhile, a low-latitude shortwave trough is forecast to move across the southern Plains and into the lower MS Valley, from Saturday/D5 into Sunday/D6. Given the expected very moist air mass in place with 70s F dewpoints, and lack of capping, scattered areas of thunderstorms are likely throughout the period. Much of the activity will occur over TX and OK, where moderate instability is forecast. However, shear will be generally weak. Given the daily cycle of thunderstorms and resulting outflow boundaries across the entire region, predictability is too low to denote any concentrated severe areas. However, sporadic severe winds, perhaps isolated hail, cannot be ruled out from the southern Plains into the lower MS Valley from Saturday/D5 into Monday/D7.
