Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0249 AM CST Fri Nov 28 2025

Valid 011200Z - 061200Z

....DISCUSSION...
A progressive upper-air pattern will prevail over the CONUS through
next week, supporting multiple rounds of surface high pressure
overspreading the Interior West, Great Plains, OH Valley, and much
of the Northeast. Static stability will limit thunderstorm
development over most locales. However, a couple instances of
surface low development are possible along the Gulf Coast this
upcoming week, which may support thunderstorm development as
seasonably rich low-level moisture returns inland, beneath
deep-layer ascent.

A surface low may first traverse the Gulf Coast on Day 5/Tuesday,
with a few strong thunderstorms possible along the warm front
(assuming adequate buoyancy can materialize). A similar pattern of
surface low development and progression along the Gulf Coast may
also occur on Day 8/Friday, with thunderstorms also possible.
Nonetheless, questions about the timing and track of the surface
lows, and the degree of instability preceding them, warrant the
withholding of severe probabilities for this outlook.
