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

.NEAR TERM UPDATE /Now Through Thursday/...No significant changes
to the previous discussion. A Severe Thunderstorm Watch has been
issued for portions of interior southwest and south central AL
until 9 PM CDT. Primary threats are from storms capable of
producing damaging wind gusts and large hail.

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 continues generally
along and north of a Silas, AL to Andalusia, AL line this afternoon
into early this evening. A more Marginal severe risk extends as far
south as a Lucedale, 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 Mobile/Baldwin
counties 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.
Supercells will likely be clipping into northern Choctaw/Wilcox
counties over the next 1-2 hours, with additional development
southeastward into interior south central AL through early this
evening.

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

&&

.SHORT TERM /Thursday night Through Saturday night/...A weak cold
front will continue to move offshore Thursday night. Meanwhile, a
southern stream disturbance will move quickly across the area. This
will lead to weak isentropic upglide and isolated to scattered
showers mainly over the southern third of the area. A cooler and
drier airmass moves into the area on Friday with highs in the upper
60s and low 70s. A cut off upper low opens up and ejects eastward on
Saturday into Saturday night. A warm front will lift northward
across the area on Saturday with strong southerly flow allowing
moisture to surge back into the area. As moisture levels increase,
rain chances will increase through the day on Saturday and into
Saturday night. /13

&&

.EXTENDED TERM /Sunday Through Wednesday/...As the trough moves east
and takes on a negative tilt, sfc low pressure will rapidly
develop and race eastward into the Mid South by Sunday afternoon
and into the Ohio Valley Sunday night. A trailing cold front will
move across the southeast Sunday afternoon through Sunday night.
It is too early to nail down exact details as timing differences
continue between models this far out. However, a large warm sector
is expected across the region with plenty of shear and
instability to support the development of severe thunderstorms.
The overall pattern and climatology support the potential of
severe thunderstorms Sunday through Sunday night. This system will
have to be watched closely through the remainder of the week.
Differences continue early next week, as the ECMWF stalls this
front offshore and maintains the chance of showers Tuesday and
Wednesday while the GFS clears the area out with a drier airmass
moving in. /13

&&

.MARINE...Light to occasionaly moderate westerly flow today will
increase to a more moderate flow Thursday as a weak front moves into
the area. Showers and storms will be possible in association with
this front, which will likely move just offshore by Thursday night.
Behind the front, a moderate to strong northeast flow is expected for
Friday. A developing weather system over the weekend will then
likely result in even stronger winds and building seas, along with
the potential for strong to severe storms. /21
