Concerning...Severe Thunderstorm Watch 290...
Valid 230024Z - 230230Z
The severe weather threat for Severe Thunderstorm Watch 290
continues.
SUMMARY...A threat for wind damage and large hail will likely
continue for a few more hours across parts of the Ark-La-Tex.
DISCUSSION...Scattered strong to severe thunderstorms are ongoing
from northeast Texas eastward into southwestern Arkansas and
northern Louisiana. These storms are located on the northern edge of
a strongly unstable airmass. Forecast soundings in the Ark-La-Tex
from the RAP have MLCAPE near 3000 J/kg, with 0-6 km shear around 50
knots, and 700-500 mb lapse rates near 7.5 C/km. This should support
supercell development, with a potential for large hail and wind
damage. Damaging wind gusts will also be possible with the more
intense line segments. This threat is expected to persist for a few
more hours, but could become more isolated as instability begins to
decrease across the Ark-La-Tex during the mid to late evening.
