Areas affected...southeast Mississippi...far southwest Alabama
Concerning...Tornado Watch 338...
Valid 191205Z - 191400Z
The severe weather threat for Tornado Watch 338 continues.
SUMMARY...A small area of supercell potential currently exists from
southern Mississippi into a small part of southwest Alabama. A brief
tornado is possible.
DISCUSSION...An outflow boundary currently extends westward out of
southern AL and into far southeast MS, where it has likely stalled.
Meanwhile, a very moist and unstable air mass remains to the west,
with upper 70s F dewpoints minimizing CIN.
Westerly flow in the boundary layer has maintained theta-e advection
into this area where low-level convergence is concentrated. A
supercell currently exists in Jones County, MS, and other storms
were beginning to form farther south.
SRH is concentrated mostly in the lowest 1 km, with values of 150 to
200 m2/s2 common, especially near the outflow boundary. It is
possible that any storms interacting with this favorable shear zone
could produce a brief tornado. As such, the tornado watch has been
expanded south to account for the motion of the aforementioned cells
and new development.
