...DISCUSSION...
On Saturday/D4, a large but progressive upper trough will move
across the Northeast, with a deep upper low over Hudson Bay. West of
the initial trough, west/northwest flow will prevail across the
CONUS, with various embedded waves. A front will linger from the
Carolinas westward into TX, but will gradually shift south as high
pressure spreads southeast out of the Plains. The undercutting cool
air will lead to substantial clouds and precipitation over the
southern Plains on Saturday, with scattered rain and thunderstorms
across the Gulf Coast states. While moist, instability will become
limited due to lack of heating in many areas, and as such severe
storms are not currently forecast.

From Sunday/D5 and beyond, rain and a few thunderstorms will
continue over parts of the Southeast as the cold front pushes
offshore, with progressive drying each day. Beyond about Tuesday/D7,
indications are that southwest flow aloft may return to parts of the
western CONUS, with gradual moisture return into the southern
Plains.
