Area Forecast Discussion
National Weather Service Mobile AL
134 PM CDT Wed Jun 24 2020

.NEAR TERM /Now Through Thursday/...Upper level shortwave energy will
move through an upper trough stretching south over the Lower
Mississippi River Valley through the Near Term. The first batch
moves across the Southeast this afternoon into tonight, with the
next round expected later tonight through Thursday. A low level
ridge is stretching west over the northern Gulf, creating deep southerly
low level flow and keeping moisture levels high. Precipitable h20
values reported from the KLIX and KJAN upper air sites ranged from
1.8" to 2.1", well above normal for the date. An upper ridge
stretching west over the Gulf of Mexico helps to direct the energy
exiting the Lower Mississippi River upper trough in an east-
northeast direction, and for the fore the forecast area, bringing a
better chance of rain to inland areas of the forecast area through
the Near Term.

Strong to severe storms remain possible over the forecast area this
afternoon into tonight. A combination of MLCapes approaching
2500J/kg, the soupy airmass over the forecast area and nearby, along
with a bit of help from a weak 850mb speed max on the southeast side
of an embedded low level trough moving across the Southeast will
help to create favorable conditions for convective downbursts.
Guidance is advertising DCape values approaching 1000J/kg on the
leading edge of the rain, enhancing any damaging downburst winds
that may occur. Weak tornadoes may also be possible, especially if a
storms follows a previous outflow boundary, but with 0-1km helicity
values advertised of 100m^2/s^2, strong/long track tornadoes are not
indicated. Will need to monitor, with this morning's weather not
quite following what the guidance is saying. With the linear nature
of winds in the model soundings, with bulk shear values of 30-35kts,
linear/bowing segments in the convection bringing strong downburst
winds is expected mode of damage. A Severe Thunderstorm watch will
be issued shortly for our Al/Fl counties except for Choctaw in
effect until 9 PM CDT/02Z.

Looking at temperatures, with better chance of convection across
portions of the forecast area along and north of I-65, better
heating south will bring temperatures closer to seasonal norms, with
below normal high temperatures. Rain cooling overnight will bring
below seasonal low temperatures north of I-65, around to a bit above
southeast.

.AVIATION...
18Z issuance...General VFR conditions were noted across the forecast
area at 17z, with local mid to low end MVFR conditions noted in areas
of ran and thunderstorms along and west of the Alabama and
Mississippi state line. As the area of rain and thunderstorm move
east over the area this afternoon, local drops to MVFR levels along
with locally strong and variable winds near the thunderstorms are
expected, with impacts to operations expected. There is expected to
be a lull later this evening into the overnight hours, but another
round of convection is expected to begin affecting the forecast area
by sunrise Thursday. Again, local drops to mid to low end MVFR
levels are expected in and near scattered to numerous showers and
thunderstorms. Southerly winds are expected through the forecast,
generally ranging from 5 to 10 knots. Locally higher near the
thunderstorms.
