Day 4-8 Convective Outlook 
NWS Storm Prediction Center Norman OK
0315 AM CDT Fri Sep 27 2024

Valid 301200Z - 051200Z

...DISCUSSION...
Early next week, the upper low in the Tennessee/lower Ohio Valleys
will beco*e an open wave and progress offshore by Wednesday, losing
amplitude with time. Upper-level troughing will shift out of the
northern Plains and into the Great Lakes early to mid next week. A
very weak surface pattern will exist ahead of the initial shortwave
trough in the vicinity of the Carolinas Monday/Tuesday. Though
modest mid-level flow enhancement will remain over the region, these
strong winds will generally be behind the main frontal zone likely
near and just offshore. Further uncertainty is introduced due to
precipitation and cloud cover. Elsewhere, cooler and more stable
conditions will move in behind the second, stronger shortwave
trough. By late next week, upper-level flow is expected to beco*e
more zonal and the strongest flow will be near the Canadian border.
Potential for severe weather continues to appear low through the end
of next week.
