....DISCUSSION...
Medium-range guidance continues to indicate that the westerlies will
trend less amplified off the mid-latitude Pacific into the U.S. late
this work week into early next week.  Large-scale flow may remain
broadly anticyclonic across the eastern Pacific into the western
U.S., but with at least a few embedded short wave troughs
progressing inland and across the Rockies.  It appears that these
will generally be low in amplitude, and only accompanied by weak to
modest surface cyclogenesis to the east of the Rockies.  Surface
ridging may linger across much of the Gulf coast region through late
next weekend, with the boundary layer over the Gulf of Mexico only
gradually begin to modify in the wake of the recent cold intrusion.
This probably will preclude a substantive return flow of moisture
through this period.  Coupled with the relatively weak forcing for
ascent, convective potential is expected to remain generally low
into at least early next week.
