...DISCUSSION...
...Monday/Day 4 and Tuesday/Day 5...
On Monday, a cold front is forecast to move southeastward across the
eastern Carolinas, southeast Georgia and Florida. It appears that
pockets of moderate instability will be possible ahead of the front
by midday. Considering that strong deep-layer shear is forecast
across much of the Southeast, thunderstorms that form near the front
could develop an isolated severe threat. Severe wind gusts would be
possible near the leading edge of a convective line. However, the
timing of the cold front as it passes through the Southeast remains
questionable, and uncertainty exists concerning instability,
suggesting predictability is low for Monday.

On Tuesday, surface high pressure is forecast to move across the
central and eastern U.S. Relatively dry and stable air should limit
any severe potential across the continental U.S Tuesday.

...Wednesday/Day 6 to Friday/Day 8...
From Wednesday to Friday, a cold front and an associated mid-level
trough is forecast to move southeastward across the central and
eastern U.S. Thunderstorm development will be possible ahead of the
trough near the front, beginning Wednesday night in the central
Plains. The most reliable model forecasts suggest that the most
likely area for an isolated severe threat on Thursday would be from
the central Plains into the mid Mississippi Valley. The severe
potential is forecast to shift eastward into the Carolinas on
Friday. Severe wind gusts and hail would be the primary threats.
During the mid to late week, instability is forecast to remain
relatively weak ahead of the front. Also, the timing of the trough
is still in question. This suggest that predictability is low from
Wednesday to Friday.
