...DISCUSSION...
For the Sunday/D4 through Thursday/D8 period, an elongated zone of
thunderstorm/wind potential will exist from the northern Plains
across parts of the Midwest/Great Lakes, and possibly extending into
parts of the Northeast. Predictability is low for this pattern given
the likelihood of ongoing corridors of storms early each day, and
variability with the position of the elongated west to east front.
However, the presence of a very moist air mass, with possibly strong
instability to the south, combined with possible waves rotating
around the large-scale upper trough over Canada, may yield storm
corridors with damaging wind potential. One or more areas may be
denoted in later outlooks as the events near in time.

At this time, rough areas of interest include the northern Plains to
Upper Midwest on Sunday/D4, and portions of the Great Lakes/Midwest
on Monday/D5.
