....DISCUSSION...
From Saturday/D4 into Sunday/D5, an elongated positive-tilt upper
trough is forecast to move gradually east across the Plains and
toward the MS Valley. There are clear predictability issues
regarding the speed of the primary southern speed max and the
amplitude of the wave, especially as it potentially accelerates
across the Southeast Sunday/D5 or Monday/D6. In addition, models are
forecasting substantial rain and thunderstorm coverage preceding any
such wave, resulting in weaker instability. However, sufficient
moisture and instability could develop given a possible
strengthening shortwave trough, resulting in severe potential on one
of those days across parts of the Southeast. A risk area could be
needed in later outlooks as predictability increases.
