...DISCUSSION...
An upper trough embedded within the mid-level westerlies is forecast
to move from the north-central states into the Northeast and Canada
on Day 4/Sunday. Although low-level moisture return may occur to the
south of this feature across the southern Plains vicinity, the
potential for organized severe storms appears low. Medium-range
guidance has come into somewhat better agreement regarding the
evolution of the mid/upper-level jet across the northern/central
CONUS in the early to middle portion of next week. Still,
differences remain in both the northward extent and quality of the
low-level moisture return across the central CONUS. Some guidance
suggests potential for isolated severe storms across parts of the
southern/central Plains into the mid MS Valley and perhaps the
Midwest from Day 5/Monday into at least the middle of next week.
However, too much uncertainty exists regarding this severe potential
to include any probabilities at this time.
