...DISCUSSION...
On D4/Monday, a seasonably strong shortwave trough is forecast to
move from the northern Rockies into the northern Plains. Some
uncertainty remains regarding the quality of moisture return into
the northern Plains by Monday afternoon, but increasingly favorable
wind profiles combined with at least moderate instability will
support an organized severe thunderstorm threat across some portion
of the northern Plains into the upper MS Valley. Probabilities will
likely need to be included in subsequent outlooks when details
regarding the timing of the upper wave and magnitude of moisture
return come into better focus. 

For D5/Tuesday and beyond, some severe threat will likely persist
across some portion of the central/northern Plains into the upper
Midwest, as a belt of stronger mid/upper-level flow to the north of
a ridge over the southern Plains/Southeast interacts with a
persistent axis of moderate-to-strong instability. Predictability
remains too low to delineate any specific areas at this time.
