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
Monday/Day 4 to Wednesday/Day 6
At mid-levels, a ridge is forecast to move from the north-central U.S. on Monday into the Great Lakes by Wednesday, as a shortwave trough moves slowly eastward from the northern Rockies into the northern Plains. In the vicinity of the ridge on Monday, an axis of moderate to strong instability is forecast to develop. In spite of limited forcing, isolated severe storms may form on Monday afternoon over parts of the north-central U.S., mainly in areas where low-level convergence becomes maximized. On Tuesday, isolated severe storms will be possible ahead of the approaching trough along a north-to-south corridor of instability in the Dakotas and Nebraska. Storms will again be possible ahead of the trough in the upper Mississippi and mid Missouri Valleys on Wednesday. The primary threats would be isolated severe gusts and hail.
Thursday/Day 7 and Friday/Day 8
The mid-level trough is forecast to move into the Great Lakes on Thursday and into the Northeast on Friday, as another trough moves into the central U.S. Ahead of this second trough, isolated severe storms will be possible on Thursday and Friday in parts of the central and northern Plains. A few of the stronger storms could be associated with severe wind gusts and hail.
