Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0628 AM CST Fri Feb 11 2022
Valid 111300Z - 121200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible late today through Saturday
morning along the Texas coast and into southeast Texas.
...Northwest Gulf coast, mainly overnight...
In the wake of a surface cyclone crossing the upper Great Lakes, a
cold front will surge southeastward into the central/southern Plains
and mid MS Valley by tonight. Ahead of the cold front, gradual air
mass modification and a weak return flow cycle will continue from
the western Gulf of Mexico into coastal areas of TX. Surface-based
buoyancy is expected near the lower TX coast within the small moist
sector by later this afternoon, but nebulous forcing for ascent and
some lingering convective inhibition suggest that storm coverage
this afternoon/evening will be rather sparse at best. Late tonight,
weak low-level warm advection and ascent, downstream from a midlevel
shortwave trough digging south-southeastward from MT to the southern
High Plains, could support elevated thunderstorm development as far
north as interior southeast TX from about 09-12z.
...Southeast FL this afternoon into tonight...
Air mass modification in a weak easterly flow regime will contribute
to the potential for some shallow convection near and just off the
southeast FL coast. However, convective depth will likely be too
shallow to support charge separation/lightning.
