   ...DISCUSSION...
   Medium-range guidance indicates that at least modestly amplified
   mid/upper ridging will continue to build and be maintained across
   the Pacific coast into the Rockies through next week.  Within the
   northwesterly flow downstream of this feature, several digging short
   wave perturbations appear likely to reinforce large-scale troughing
   across the eastern U.S., while also contributing to occasional
   surface cyclogenesis from the lee of the northern Rockies through
   the northern and middle Atlantic Seaboard.  However, these are not
   likely to be accompanied by a strengthening southerly return flow
   emanating from the Gulf Basin.  Regardless, in the wake of a
   reinforcing cold intrusion across much of the Florida Peninsula, and
   through much of the Gulf Basin, early next week, it appears that
   boundary-layer modification over the Gulf will not become conducive
   to appreciable inland low-level moisture return.
