....DISCUSSION...
Spread among the various models concerning short wave developments
increases substantively through this period.  However, in general,
it appears that the westerlies may trend at least a bit more zonal
off the mid-latitude Pacific into the U.S. late this coming work
week through next weekend.  This probably will be accompanied by
moderating temperatures across the middle and southern tier of the
U.S. to the east of the Rockies, particularly across the central and
southern Great Plains, as surface troughing develops to the lee of
the southern Rockies.  A corresponding southerly return flow may
begin to contribute to moisture return off a modifying
boundary-layer over the western Gulf of Mexico.  However, low-level
moistening probably will remain insufficient to support more than
rather weak destabilization through this period.  Coupled with the
apparent lack of stronger large-scale forcing for ascent, the
convective potential, including the risk for severe storms, appears
likely to remain low.
