...DISCUSSION...
Gradual deamplification of the upper flow field is forecast over the
U.S. during the medium range, with models generally in reasonable
large-scale agreement.  Both the persistent western ridge, and
eastern trough, are expected to diminish in intensity, permitting a
more west-to-east band of flow to evolve over the northern quarter
of the CONUS with time.

Given the deamplifying flow field expected, and no major upper
features apparent at least through the first several days of the
period, any severe risk will likely be limited areally, and
associated with smaller scale disturbances aloft/more subtle surface
features.  As such, lack of predictability precludes any areal
delineations of severe potential at this time.
