Due to clouds and convection in Mississippi, two areas of
instability develop over central Alabama this afternoon and early
evening. One was close to Sumter and Marengo Counties, while the
other was the northeast third of the area. The convection was
moving mainly slowly east southeast. Therefore, had to rearrange
the pops for this evening. The northeast area has since moved into
Georgia and diminished somewhat, while the highest pops will be
south and southwest. After midnight, there may still be some
activity north and left a chance in. The 00z BMX Raob still has
noticable dry air below 700mb, and this will continue to limit
overall activity too. Therefore, the updates consists of the pop
update and a temperature trend adjustment. Low clouds and patchy
fog are expected to develop overnight with lows in the 60s. The
scattered convection still remain possible Friday and the
discussion below holds.

(This afternoon through Friday)
Issued at 1247 PM CDT THU APR 18 2024
A broad area of low-level ridging is centered over the Central and
Eastern Gulf of Mexico while lower amplitude mid-level ridging is
also present over the Eastern CONUS, producing westerly flow aloft.
Warm conditions are expected this afternoon with a mix of sun and
clouds. Highs will reach the mid 80s. There will be an opportunity
for some storms late today and into the evening hours as an embedded
shortwave moves from the Midsouth region and across the Tennessee
Valley. Some thunderstorms associated with this feature are already
ongoing near the Mississippi River, but that activity has really
struggled to maintain intensity with eastward extent as we still
have residual dry air in the mid-levels. Some deeper moisture is
confined near the shortwave, so expect the thunderstorms to
eventually move into western portions of the area early this evening
as the shortwave moves east, but instability will be on the decline
by that point. Any strong storms moving through Mississippi should
be on a weakening trend as they reach Central Alabama, so expect
the activity to be sub-severe.
Meanwhile, a surface low is forecast to moves towards the Ohio
Valley tonight dragging a cold front across the Lower MS River
Valley. Convection along the southern sections of the front will
really struggle as it moves further into an unfavorable environment
dominated by the Gulf ridge and lacking in deep moisture. As such,
expect another round of decaying showers and a few storms to affect
primarily the far northern portions of the area after midnight
before diminishing by sunrise. Patchy fog appears likely tomorrow
morning, especially in the south. Will monitor trends to see if a
Dense Fog Advisory is needed. The frontal boundary will be near the
I-20 corridor by tomorrow afternoon. As temperatures warm into the
lower to mid 80s, some isolated to scattered thunderstorms will
develop. Despite MUCAPE ranging from 2000-3000 J/kg along the
surface boundary, thunderstorm growth is expected to struggle
through the dry air, limiting coverage, intensity, and longevity,
but gusty thunderstorm winds will be possible in a few instances.
