Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
1235 PM CDT Fri Jun 22 2018

...SEVERE THUNDERSTORMS POSSIBLE TODAY ACROSS PORTIONS OF THE
REGION...

.UPDATE...
Updated for 18Z aviation discussion

&&

.AVIATION...
18Z TAF discussion:

Most ceilings (at least away from the midst of thunderstorm
activity) have improved to VFR at this point although there remain
lots of scattered to broken decks near or above 3 kft around the
region. Main thunderstorm activity is training southeast across SE
AR, NE LA, and SW MS, and will continue to do so through the
afternoon hours. Other pockets of more isolated storms will also
tend to pop up through the day. Any locations impacted by storms
could experience very gusty winds and temporary IFR conditions
through early this evening. Most activity will diminish by late
evening with low level ceiling issues, mainly in the VFR range,
expected to build in again late tonight in most areas. There is
potential for additional thunderstorm activity to approach from
the northwest late tonight and may impact GLH/GWO/CBM/GTR corridor
late tonight through Saturday morning. Otherwise, expect surface
winds away from thunderstorms to be mainly from the southwest at
10 to 15 mph and occasionally gusty. /BB/

&&

.DISCUSSION...

Morning discussion update:

As expected, complex convective evolution in progress this
morning within a background environment containing a rather
volatile combination of wind shear and instability. Main 850 mb
thetaE advection axis early this morning was driving strong to
severe thunderstorms into far northwestern zones (i.e., Ashley Co
AR) with activity tending to train and remain tied to this axis.
The potential for this process to repeat a few times in western
zones will remain into the afternoon and heightens the flash flood
risk in these areas. The HWO and graphics were updated to reflect
this thinking.

Recently, the somewhat organized and robust convective cluster
coming out of Ashley Co and Morehouse Parish LA has managed to
forward propagate downstream of mentioned thetaE axis and into
building low level instability over southwestern and central
zones. Thinking convection may struggle to maintain severe intensity
toward the Jackson Metro area, but ample wind shear (bulk deep
layer shear of 30+ kts) may allow kinematic boosting to ambient
instability pool potential. Further west, better instability
increases confidence of severe convection continuing downstream
into these areas into the afternoon hours. Also worth mentioning a
secondary axis of thunderstorms brushing far northern and
northeastern zones will be something to watch and severe (and
non-negligible flood) potential will be there at times. In these
northern areas the instability will not be as great (e.g., working
CAPE values mainly less than 2500 j/kg), but deep layer wind shear
could be 40+ kts plus, which is extremely impressive for this time
of year in this region.

The recently issued SVR Watch #197 basically outlines the best
risk for severe thunderstorms through late this afternoon,
focusing mainly on the southwest half of the area. Wind damage
will be the primary risk with severe storms, although hail cannot
be ruled out (particularly in NE LA). In addition, low level
shear vectors are lined up in such a way to make the possibility
of a brief spin up tornado non-zero.

Most of the activity should be diminishing or exiting between late
this afternoon and early this evening. There does remain some
potential for another potent cluster of storms to come in from the
northwest and impact at least northern zones late tonight through
early Saturday. Still a lot of uncertainty regarding this and we
will focus efforts with the afternoon forecast package to provide
more detail. /BB/

Prior discussion below:

Today and Tonight: Early morning water vapor imagery/RAP analysis
showed the circulation around a nearly stacked low over southern
Illinois with a shortwave nearing the Ozarks that will continue to
swing around the base of the low today. Surface analysis had the
associated cold front dropping over the Missouri bootheel and
extending southwest across southwest Arkansas into northeast Texas.
The shortwave is expected to help initiate convection along the cold
front later this morning. Models agree that this activity will
spread east southeast into our northwest most zones shortly
thereafter eventually spreading to the Highway 84 corridor by late
afternoon. Our tropical airmass with greater than two inch PWATs got
dry slotted yesterday but a moist airmass remains over the region as
GOES total PW imagery suggests PWATs continue around 1.6 inches over
our CWA early this morning. Surface observations also had mid 70F
dew points over our CWA. Although the storms will get an early
start in our north they should encounter an environment with MLCAPEs
in excess of 2000j/k. Considering the flow around the low to our
north contributing to deep layer bulk shear around 40 kts, the
environment will support the potential for severe storms with
damaging wind and hail being the main threats. Locally heavy
rainfall will also be possible and a brief tornado or two cannot be
ruled out.

The nearly stack low will move northeast toward the Ohio River
Valley tonight and weaken stranding the cold front to stall across
our northern zones this evening before drifting back north toward
morning. Most of the convection over our CWA will dissipate this
evening with the loss of daytime heating but, convection will linger
in proximity of the frontal boundary through the night. There are at
least a couple models that suggest a complex of storms may develop
tonight and track along the stalled front, possibly dropping into
our CWA prior to sunrise. Wl maintain a MARGINAL area in our HWO
across the Highway 82 corridor to account for this threat.
Otherwise, temperatures will be held close to normal today due to
the convection and cloud cover but Saturday morning lows will be
warmer than normal again. /22/

This weekend: As a mid/upper trough pulls northeastward away from
the area, a surface front stalled across east AR into north MS will
retreat northward, with a surface ridge building in along the Gulf
Coast. This will begin to confine convection north of the region as
capping increases from the south. However, there remains the
potential for a complex of storms to brush the northern fringe of
the CWA into early Saturday as suggested by the 00Z Euro and some
CAM solutions, so chance POPs were maintained into that time period.
Otherwise, with fewer clouds/showers, temps will tick up again this
weekend, and given the remaining moist airmass, heat stress will
become more of a concern. We'll continue mention in the HWO for heat
indices approaching 105 over most of the CWA on Saturday, also now
including Sunday as well. It is possible a heat advisory may be
needed eventually for some portion of the area.

Monday through Thursday: The surface ridge will begin to retreat
eastward, resulting in an increase in diurnal convection as our
region moves to the periphery of said ridge. Outside of the rain,
generally warmer conditions are expected as mid/upper heights
increase over the area. With a rather humid airmass remaining in
place, heat stress could continue to be a concern. However, the
greater potential for clouds/rain will create uncertainty over daily
peak apparent temps. Eventually, we may need to highlight a heat
stress risk on one of more of these days in the HWO/graphics/NPW.
