Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
1026 AM CST Thu Jan 09 2025

Valid 091630Z - 101200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

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

...Discussion...
A highly amplified large-scale trough will move gradually eastward
across the southern Rockies/Plains and northwest Mexico through the
period, while several embedded shortwave impulses overspread the
southern Plains. A related plume of strengthening warm advection
will shift eastward across south/central and east TX and eventually
into the central Gulf Coast states. While the surface-based warm
sector will remain offshore, steep midlevel lapse rates (and weak
elevated buoyancy) atop a stable boundary layer will support very
isolated lightning flashes embedded in a swath of precipitation
overspreading the region.
