....DISCUSSION...
The extended period will feature a tranquil upper-air pattern for
severe weather this upcoming weekend.  Medium-range models show a
generally low-amplitude, progressive flow pattern over the
contiguous U.S.  Models show moisture returning north into the lower
MS Valley/Mid South region, perhaps as early as Monday (day 6),
beneath a strong upper jet.  Some risk for severe thunderstorms may
materialize during the Monday-Tuesday timeframe with this forecast
pattern.  By Wednesday (day 8), there is a signal for a progressive
mid-level trough to move from the Desert Southwest into the central
U.S.  Confidence is low at this time in the aforementioned scenario
due to large model variability for next Wednesday.
