Day 4-8 Convective Outlook

...DISCUSSION...
A broad northwesterly upper flow regime will be in place across the
CONUS early this week, before a pronounced mid-level trough
amplifies greatly while tracking across the eastern CONUS through
the remainder of the week. As this occurs, surface low development
is likely around the Great Lakes, with a strong cold front poised to
sweep across the northern Plains to the East Coast during the Days
5-8 (Tuesday-Friday) time frame. Cool and stable conditions will
usher in behind the cold front. However, Gulf moisture may advect
north-northeast ahead of the front along the East Coast toward the
end of the week. Assuming forcing for ascent is not purely
anafrontal, it is plausible that at least isolated severe storms
could develop along the East Coast around Days 7-8
(Thursday-Friday). However, confidence in the specific timing and
magnitude of any severe threat this far in advance is too low for
the introduction of severe probabilities at this time.
