...DISCUSSION...
A northwest flow regime will persist across the Plains through
Saturday/D6 as an upper high holds over the southwestern states. The
ridge is expected to break down late D6 through the remainder of the
period into Monday/D8, as a strong wave moves southeastward into the
Great Lakes, and a weaker wave potentially moves into the Great
Basin/Four Corners states on Sunday/D7. This overall pattern will
maintain relatively stable conditions over most of the CONUS, with
high pressure over the southeastern states including the Gulf of
America. Further, as the stronger wave potentially moves across the
Great Lakes and into the Northeast, a reinforcing cold front is
likely to plunge south over much of the central and eastern states
into the D7/D8 time frame. While limited moisture may precede this
cold front, overall potential for destabilization appears to be
minimal.
