Area Forecast Discussion
National Weather Service Mobile AL
146 PM CDT Wed Apr 8 2020

.NEAR TERM /Now Through Thursday/...A warm and moist airmass is
in place across the forecast area this afternoon underneath
increasing zonal flow aloft. Temperatures are warming into the
upper 70s to mid 80s around the region, while surface dewpoints
are in the upper 60s to lower 70s. This thermodynamic environment
is contributing to MLCAPE values around 2000 J/KG across our
forecast area this afternoon. The increased mid to upper level
flow is resulting in effective bulk shear values between 40-50
knots across the area, with the highest bulk shear values clipping
interior portions of southeast MS and southwest/south central AL.
A subtle shortwave impulse moving east-southeast toward our
forecast area from northern and central MS will aid in the
development of scattered showers and storms, initially just N/NW
over our area by early this afternoon, but these could develop
and/or move into our interior southeast MS and southwest/south
central AL counties later this afternoon into early this evening.
Effective bulk shear values up to around 50 knots, MLCAPE values
around 2000 J/KG and steepening low to mid level lapse rates up to
around 7 C/KM will favor storm organization over our interior
zones, with a few storms potentially becoming capable of producing
damaging winds and hail to the size of quarters or larger. SPC
has outlined a Slight Risk of severe storms especially along and
north of the U.S. Hwy 84 corridor this afternoon. A more Marginal
severe risk extends as far south as a Wiggins, MS to Crestview, FL
line. We are already seeing storms develop along a zone of
moisture convergence across interior portions of the northwest FL
panhandle and into Baldwin county AL. Additional storms could
develop along the I-10 corridor through the afternoon, a few of
which could also have strong enough updrafts for a marginal
wind/hail threat. Storms may linger into early this evening,
before gradually diminishing after around 9 PM.

Patchy fog may develop across central and southern portions of the
region late tonight into early Thursday morning.

A cold front will push southward into central portions of MS/AL
overnight into early Thursday morning before pushing southward to
near the coast by Thursday afternoon. A secondary line of showers
and thunderstorms may develop along this boundary to the north of
our CWA overnight into early Thursday morning, but high resolution
and short range models have shown a gradual weakening trend with
this convection as it moves into interior portions of the forecast
area early Thursday morning. Still cannot rule out a brief strong
storm north of the Hwy 84 corridor early Thursday morning, but the
better potential for severe storms are currently expected to
remain located to the north and northwest of our CWA overnight
into early Thursday morning. For now we plan to maintain a low
chance of showers and storms along the front as it moves south
across our region Thursday morning. /21

.AVIATION...
18Z issuance...VFR this afternoon though localized MVFR will be
possible, especially near scattered SHRA/TSRA that will develop
around the region into early this evening. IFR/LIFR conditions
return late tonight into early Thursday morning with the
development of stratus and patchy fog. /21
