Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0227 AM CST Sat Dec 14 2024

Valid 171200Z - 221200Z

....DISCUSSION...
An upper trough over the High Plains vicinity Day 4/Tue morning will
deepen and track east to the MS Valley by Day 5/Wed, and to the
Atlantic coast by Day 6/Thu. As this occurs, a cold front will move
across the south-central and southeast states, pushing offshore the
Gulf and Atlantic coasts by late Day 5/Wed into early Day 6/Thu.
While thunderstorm potential will be possible with this system,
severe potential appears limited, given weak instability and
deep-layer flow oriented parallel to the surface boundary (leading
to more anafrontal processes).

With the strong front moving well into the Gulf of Mexico,
boundary-layer moisture will remain scant heading into the end of
the forecast period, and severe-thunderstorm potential is expected
to remain low Days 7-8/Fri-Sat.
