....DISCUSSION...
Global models continue to indicate that ridging will prevail over
the western U.S. through the medium-range period.  As a result, a
gradual expansion of eastern U.S. troughing/cyclonic flow is
projected.

As this occurs, a Canadian cold front is forecast to sag southward
across the eastern half of the country, gradually suppressing higher
theta-e low-level air southward through the period.  As this front
advances, beneath the southern fringe of stronger flow aloft,
local/limited severe weather will likely occur, peaking diurnally
each day.  However, the combination of model differences with
respect to the timing/location of the sagging baroclinic zone, and
this overall pattern evolution not particularly conducive for
widespread severe weather, precludes any inclusion of risk areas
through the end of next week.
