...DISCUSSION...
A deep upper-level trough initially over the eastern CONUS on
D4/Sunday is forecast to move offshore early next week. In the wake
of this trough and its attendant cold front, a surface ridge is
expected to persist over much of the eastern CONUS through mid week.
This ridge will likely prevent the northward return of richer
low-level moisture for most of the extended-range period, which
should tend to limit organized severe-thunderstorm potential across
much of the CONUS.

There is some potential for the influence of the eastern surface
ridge to wane by D7/Wednesday into D8/Thursday, while some guidance
suggests a mid/upper-level trough will approach the central/northern
High Plains during this time frame. Should this occur, there could
be some increase in severe potential, though predictability remains
rather low at this forecast range.
