A new severe thunderstorm warning has just been issued for parts of Clarke and Monroe Counties in South Alabama. This is the more southern storm that is between Jackson and Thomasville. The northern storm weakened and is now passing north of Thomasville.

Areas affected…Southern and Central Alabama…Western Georgia

Concerning…Severe potential…Watch possible

Valid 091238Z – 091515Z

Probability of Watch Issuance…40 percent

SUMMARY…An isolated large-hail and wind-damage threat will
continue to develop across parts of southern and central Alabama
this morning. Cells are expected to increase in coverage. Weather
watch issuance may need to be considered later this morning.

DISCUSSION…Latest surface analysis shows a warm front from
southern Mississippi eastward across southern Alabama. Thunderstorms
are forming in the vicinity of the front to the west-southwest of
Montgomery, Alabama. Additional storms are developing to the
southwest of Columbus, Georgia. RAP forecast soundings along the
front suggest that MUCAPE is near 2000 J/kg. Effective shear is
estimated in the 35 to 40 kt range according to regional WSR-88D
VWPs. This environment will support supercell development over the
next few hours. Cells that track east-northeastward near the front
may be associated with a wind-damage and brief tornado threat. The
storms will also produce isolated large hail. Cells that move to the
north of the warm front will predominately have a large hail threat.
