....DISCUSSION...
The general pattern of a mid-upper trough over the central/eastern
CONUS will persist through much of the extended outlook period, with
the residual influence of an arctic air mass limiting buoyancy for
the vast majority of the CONUS.  There may be some potential for
thunderstorms in the vicinity of south FL by early Wednesday (late
D4 into D5).  However, forecast confidence in the sub-synoptic
details is low given a low-amplitude midlevel trough crossing the
northern Gulf of Mexico (with associated timing questions).  The
residual arctic air mass and a probable lack of substantial surface
cyclogenesis suggest that severe storms are unlikely.
