...DISCUSSION...
In the wake of a vigorous short wave perturbation and associated
surface cyclone accelerating northeast of the upper Great Lakes into
the higher latitudes, a lingering near-surface frontal zone across
the lower Great Lakes and Ohio Valley into the central Great Plains
may provide a focus for occasional thunderstorm development into the
middle to latter portion of next week.  However, this may largely
remain beneath the northern periphery of initially prominent
mid/upper ridging slowly beginning to retrograde from the Southeast
toward the Southwestern international border area.  Forcing for
ascent and destabilization may not support more than rather isolated
and/or marginal severe thunderstorm potential, and even latest
available AI guidance generally suggests that this limited potential
will wane by late week into next weekend.
