....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 becomes 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 become 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 accompanied by potential
for more than isolated strong to severe thunderstorm development
across the northern Intermountain region into northern U.S. Rockies.
