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
Medium-range models continue to indicate that the center of strong mid-level ridging building northeast of the Four Corners states will shift across the middle Missouri Valley early next week, where it may reach peak intensity by about Tuesday, before becoming suppressed. Even as this commences, mid-level ridging in the westerlies may be maintained near and north/northeast of the international border, from the Great Plains through the Great Lakes, while large-scale downstream troughing amplifies southeastward across the Northeast.
Associated with this evolution, a plume of very warm elevated mixed-layer air still appears likely to advect on the southern fringe of a belt of strengthening flow around the northern through northeastern periphery of this ridging. As the nose of the warmer air overspreads the Great Lakes region early next week, forcing for ascent associated with warm advection could begin supporting organizing thunderstorm clusters potentially impacting portions of New England, and/or the lower Great Lakes through Mid Atlantic.
As guidance suggests that the westerlies will initially remain split downstream of the ridge, and a potentially notable short wave trough (and associated cold front) migrating around its periphery and eventually suppressing it, it remains unclear how potential frontal and pre-frontal convection will pan out on any particular day. Due to both synoptic and sub-synoptic predictability issues, severe probabilities remain at less than 15 percent in the day 6-8 time frame. However, this probably will change in later outlooks closer to this time period, when the potential for introducing unduly large forecast false alarm decreases.
