MS...far southeast AR

Concerning...Severe potential...Watch possible=20

Valid 310539Z - 310745Z

Probability of Watch Issuance...40 percent

SUMMARY...Continued/developing severe thunderstorm potential is
uncertain. Trends are being monitored for possible watch issuance.

DISCUSSION...Isolated thunderstorms are developing along the surface
cold front draped across southeast AR into east TX. An additional
cluster of storms continued across east TX to near the Sabine River
in western LA. While the airmass ahead of these areas of convection
remain unstable, large-scale ascent continues to shift northeast of
the region. Only modest convergence along the front is noted in weak
surface wind observations across MS/LA. A lack of stronger forcing
may limit overall severe potential. However, favorable vertical
shear and MLCAPE values at or above 1500 J/kg amid steep midlevel
lapse rates could support severe storms, mainly capable of large
hail and perhaps strong gusts. Trends will be monitored for possible
watch issuance.
