...DISCUSSION...
Medium-range models indicate that mid-level flow across the northern
mid-latitudes may trend less amplified by the middle of next week,
as a mid-level low over northern Quebec weakens/redevelops eastward
into the northwestern Atlantic and a prominent high over
northwestern Canada beco*es suppressed.  As this occurs, it appears
that low-level cooling and drying may advance southward toward the
Southeast and lower Mississippi Valley, beneath generally weak flow
associated with mid/upper ridging.

Developments across the West remain more uncertain, but it does
appear that persistent mid-upper ridging will beco*e suppressed.
While it is possible that large-scale mid-level troughing may evolve
across the Pacific Northwest and Canadian/northern U.S. Rockies
vicinity, it is not clear that this will be acco*panied by potential
for more than isolated strong to severe thunderstorm development
across the northern Intermountain region into northern U.S. Rockies.
