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/Saturday - Northern Plains
A strong trough will advance into the Northwest CONUS on Saturday with a strong mid-level jet extending from the Great Basin to the northern Plains. A lee cyclone will develop across eastern Wyoming into western South Dakota. Southerly flow will strengthen and advect low to mid 60s dewpoints northward. This will lead to strong instability by the late afternoon across the western Dakotas. There is still some uncertainty with the evolution of the upper-level trough which will have some impact in the timing and location of the severe weather threat on Saturday. At this time, have confined the 15% area to where the greatest severe weather threat appears likely Saturday afternoon/evening, but this area may need to be refined in future outlooks.
Day 5 and Beyond
Severe weather will be possible across portions of the Northern Plains into the Upper Midwest Sunday and into next week. However, predictability remains too low to highlight areas in this timeframe. The presence of strong to very strong instability across a large region with multiple shortwave troughs emerging from the primary trough centered over the West will surely support severe weather potential most days. However, probabilities for specific areas cannot be added until the upper-level pattern becomes more clear.
