...DISCUSSION...
A progressive northern stream will continue through the Day 4-8
period. The overall severe threat early in the period will likely be
somewhat diminished over the Great Lakes vicinity due to prior days
convection and potential for multiple MCSs to impact the broader
Midwest region. The mean trough in place across the north-central
U.S. will weaken somewhat early in the work week. However, by the
end of the period, around Day 7/Wed, guidance suggests another
compact shortwave impulse will migrate through the larger-scale
trough from the northern High Plains toward the Great Lakes once
again. This could result in an increasing severe threat, but
uncertainty remains too high to include severe probabilities at this
time.
