Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
701 PM CDT Sun Jun 18 2023

...New AVIATION...

.DISCUSSION...
Issued at 356 PM CDT Sun Jun 18 2023

Overview...

Severe storms will continue today and tonight as a short wave is
fueling an MCS and pushing southeastward into a very unstable
environment. 5800 j/kg of CAPE have been observed along with very
steep midlevel lapse rates around 8 c/km. Unseasonably strong deep
layer shear is helping to maintain these storms and and stagnant
pattern is fueling multiple rounds over several days. This is likely
to continue into tonight until Monday as an upper low traverses
across Tennessee and Alabama. This should turn flow northerly
across the area and advect drier air and should bring reprieve
from this current unsettled pattern for much of the area, but it
should be noted that climatology suggests it may be difficult to
maintain a drier airmass. As the upper low influences our area,
the stalled frontal boundary that has been in the vicinity of the
I-20 corridor should push south and west. Given available moisture
and instability, storms are still possible Monday along this
boundary in far southwest Mississippi and eastern Louisiana.
Throughout the week, temperatures and dewpoints should be
relatively lower providing some relief for much of the area.

Today and tonight...

Severe storms from this morning have cleared the area and skies are
clearing from west to east. Mid to upper 70s dewpoints are being
observed in southern Louisiana and this plume of moisture is
being advected into our area as evidenced by satellite imagery and
observations across the southeast. This should set up a nice
recovery of airmass ahead of a deepening low pressure system. As
of 1:40 PM, surface pressure measured was 1010mb and is falling
quickly, with modeled pressure falls to be as much as 6 mb in 6
hours. Many CAMs are in agreement with an intense QLCS that pushes
through later this evening and into tonight. Favorable convective
parameters (3500+ j/kg CAPE, vertical totals 31, midlevel lapse
rates 8 c/km) will be supportive of damaging wind gusts and large
hail once again. However, unlike previous events, southeasterlies
are being observed across the area as a boundary pushes northward
from southern Louisiana, which could increase tornado potential
with favorable low level shear. HRRR depicts 200-300 m^2/s^2 0-1
km SRH and WSW oriented shear vectors. CU fields are observed
along the boundary and mesoanalysis shows 5000-7000 j/kg of SBCAPE
across southern Louisiana, which will be supportive of rapid
upscale growth. /SAS/

Monday through next weekend...

Looking ahead to tomorrow, a residual boundary from tonight's
convection will serve as the main focus for a corridor of yet
another round of storms, with damaging wind gusts and large hail the
primary threats given 3500+ j/kg of CAPE and vertical totals 28-31.
There is however notably weaker shear as the pattern begins to wind
down and this may preclude extreme intensity, however strong to
severe storms are still probable along this boundary. Thankfully the
focus will be south and west of most of our area, however eastern
Louisiana and extreme southwest Mississippi may be impacted.

As mentioned previously, the pattern should wind down this week,
replaced by a rex block pattern that should relieve us from most
activity in the midst of an upper low advecting drier air on the
backside. Climatology dictates however that maintaining a drier
airmass will be difficult and rain and storms are still possible
daily, therefore have maintained pops. Despite daily pops, the
upcoming week should feature more seasonable norms. /SAS/
