....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE
SOUTHERN PLAINS...

....SUMMARY...
Isolated severe hail is possible across parts of west/north Texas
into southern Oklahoma.

....Southern Plains...
The overall general pattern/regime will remain similar to yesterday
with moderately strong southwesterlies aloft influencing the region
and mostly bouts of elevated convection, some of which could produce
hail on a very isolated basis. A cold front will settle a bit
southward across west/central Texas, while remaining
quasi-stationary across northeast Texas into northern Louisiana and
central Mississippi. Semi-persistent warm advection/isentropic
ascent will continue to influence persistent convection particularly
across the ArkLaTex/ArkLaMiss today. Renewed convective development
should occur farther west across west/north Texas into southern
Oklahoma late this afternoon, and particularly tonight. This will be
as warm advection modestly increases and as the region begins to
come under the influence of weak height falls via an upper trough
spreading eastward over the central Rockies. Sporadic/very isolated
instances of hail may regionally occur today and tonight owing to
moderately steep mid-level lapse rates and upwards of 1000-1500 J/kg
source region MUCAPE, in the presence of 40+ kt effective shear.
