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
Day 4/Wednesday
The large-scale pattern will feature an upper high over the southern High Plains with ridging extending into the northern Plains and upper MS Valley. Meanwhile, broader-scale troughing will persist across the eastern CONUS, anchored by an upper low over the Mid-Atlantic.
A very moist air mass is expected to contribute to moderate to strong instability by afternoon along a cold front over the Southeast. While vertical shear will remain rather weak, the strong buoyancy will be supportive of locally intense downdrafts capable of damaging winds. Elsewhere, a few strong to severe storms appear possible within a moist upslope regime over the central High Plains, as well as along a cold front moving into the northern High Plains.
### Days 5 and 6/Thursday and Friday
The southwestern U.S. ridge/eastern U.S. trough configuration will be maintained this period. Between those features, a notable short-wave trough is forecast to track from the northern Plains into the mid MS Valley along with a surface frontal system. Persistent low-level ridging from the Great Lakes into the Gulf Coast states will limit the breadth of an unstable warm sector to the northern and central Plains on Thursday, where thunderstorms are expected. Vertical shear is not forecast to be particularly strong; however, some potential exists for an organized severe weather episode. Additional strong to severe storms appear possible along the front in the Ozarks on Friday. Both days will continue to be monitored for the possible inclusion of severe weather probabilities in subsequent forecasts.
### Days 7 and 8/Saturday and Sunday
There is good agreement across the ensemble means in the progression of a more significant short-wave trough from western into central Canada with the southern fringe of more substantial height falls overspreading the northern Rockies into the northern High Plains on Sunday. That upper-air system will be attended by a cold front that could be the source of severe storm development in those areas Sunday afternoon into night.
