....DISCUSSION...
A deep mid/upper-level trough is forecast to move across the eastern
CONUS D4/Sunday into D5/Monday, as a strong upstream shortwave
trough digs into the Great Lakes region. Guidance varies regarding
the strength and timing of a mid/upper-level cyclone that may
develop within the southern portion of the initial large-scale
trough across parts of the Southeast. The strongest solutions (such
as the 30/00Z GFS) would support some strong-storm potential across
parts of FL into the Coastal Carolinas, but the current consensus is
for a persistent surface ridge to suppress inland low-level moisture
return and limit the organized-severe threat.

For D6/Tuesday and beyond, predictability decreases regarding the
evolution of the upper pattern, but most guidance continues to
depict a dearth of low-level moisture and instability across the
CONUS through the middle of next week.
