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
Severe weather is possible along a frontal zone from the Mid-Atlantic to the southern Plains on Monday. The specific areas of threat will be defined by the locations of individual shortwave troughs embedded within the broader cyclonic flow. These small-scale features lack consensus at the Day 4 timeframe which precludes 15% severe weather probabilities at this time.
By Day 5/Tuesday, some severe weather threat is possible across portions of the central High Plains. There is decent model agreement showing moderate northwest flow aloft across eastern Colorado and vicinity on the eastern periphery of a western CONUS ridge. However, there is considerable spread in moisture return among the guidance. Should adequate moisture advect into the region, a northwest flow severe weather event is possible in the eastern Colorado vicinity. This will need to be monitored.
Day 6 and beyond, model spread increases which limits predictability. Most guidance shows moderate northwesterly flow across portions of the Plains, which would suggest continued severe weather episodes during the extended period. However, specific days and locations cannot be highlighted at this time due to aforementioned predictability challenges.
