Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
0655 AM CST Sat Dec 07 2024

Valid 071300Z - 081200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected through tonight.

...Discussion...
Within a split flow regime, the southern-stream upper low over the
Southwest Deserts/northern Mexico will beco*e more
east-northeastward progressive today, while a low-amplitude belt of
progressive westerlies evolves across the northern tier and Canada.

Semi-persistent and east/northeastward-expanding thunderstorm
potential today will be focused across much of central/east/north
Texas and possibly nearby parts of the ArkLaTex and/or far southeast
Oklahoma. These will be elevated thunderstorms aided by DPVA and
semi-persistent warm advection and elevated moisture transport.
Severe thunderstorms are unlikely given the limited buoyancy.
Elsewhere, a few lightning flashes could occur late tonight near
coastal Washington as lapse rates steepen in the wake of an
inland-advancing front.
