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
D4/Thursday - Central/Northern High Plains
Upslope flow will strengthen across the central/northern High Plains on Thursday as a surface low deepens across the southern High Plains. This, combined with a passing mid-level jet streak and shortwave trough, should result in scattered storm development across the High Plains. The most likely corridor will exist from northern Colorado into eastern Wyoming and far southwestern South Dakota where the stronger mid-level flow/forcing overspreads the unstable warm sector.
Beyond Day 4 there will likely be multiple days with eventual severe weather probabilities given the amplifying trough across the Northwest and moderate mid-level flow overspreading the northern Plains where instability will also be quite strong. However, at this time, there is considerable uncertainty with the timing/location of each of the mid-level shortwave troughs, and for when the core of the jet streak associated with the Northwest CONUS low ejects into the Plains.
Due to these uncertainties, no probabilities have been added beyond Day 4, but eventual probabilities are anticipated in later outlooks.
