....DISCUSSION...
While guidance varies regarding synoptic-scale details (especially
later in extended range), there is general agreement that broad
upper-level troughing will cover most of the CONUS this weekend into
next week, except for occasional upper ridging over the Northwest.
Multiple frontal passages will tend to suppress the inland advance
of Gulf moisture, and stable conditions will the potential for deep
convection over most of the CONUS into next week. Thunderstorm
potential may accompany occasional moisture return across areas near
the TX Gulf Coast and also across the FL Peninsula. However, with
stronger large-scale ascent and deep-layer flow/shear expected to
remain displaced well north of favorable instability,
severe-thunderstorm potential currently appears limited through the
extended range.
