...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PORTIONS OF
OKLAHOMA INTO THE OZARKS AND ARKLATEX REGIONS...

...SUMMARY...
Strong/isolated severe thunderstorms capable of producing marginal
hail and/or wind remain possible across parts of the south-central
states this evening and into the overnight hours.

...Eastern Oklahoma into the Ozarks and Arklatex...
Showers and thunderstorms are ongoing near and in the wake of a
strong/southeastward-surging cold front, from eastern Oklahoma
northeastward into the Midwest.  The strongest convection is ongoing
from the Ozarks portion of the area and southwestward, in the
vicinity of the advancing front.

While a moist warm sector precedes the front, the boundary layer
remains capped.  As a result, storm development has been confined to
the immediate frontal zone and into the cool sector, where
large-scale ascent is maximized.  Though storms have remained
generally weak, ample shear persists -- aided by moderate westerly
mid-level flow.  This, combined with ample instability above the
capping layer, suggests that potential persists for a few stronger
storms to evolve this evening and into the overnight hours. 
Marginal hail and locally gusty winds will be possible with the more
robust storms, with risk shifting southeastward with time in tandem
with frontal progression.
