Area Forecast Discussion
National Weather Service Jackson MS
435 PM CDT Fri Jun 22 2018

...SEVERE THUNDERSTORMS POSSIBLE THROUGH EARLY THIS EVENING OVER
PORTIONS OF THE REGION...

.DISCUSSION...

Through the day Saturday:

Solid convective cluster has finally taken shape over the
northwest portion of the forecast area in the last few hours, with
this cluster advancing steadily southeast toward the heart of the
region. Throughout the day convection has shown a tendency to
"back-build" into an impressive nose of warmth and moisture
advection aloft anchored over the Arklamiss Delta. Lately this
advection feature has opened up a bit and is less focused, aiding
the ability of convection to start propagating southeast.
Meanwhile, the cold pool from persistent convection over
northwestern zones throughout the day has generally advanced well
southwest of most vigorous convection, thus ensuring the bulk of
storms were "elevated" above the surface, reducing their
respective potential to produce severe weather.

Anyway, latest trends are increasing severe potential once again
into early this evening, especially over the western two-thirds of
current SVR watch # 197. The main risk through early this evening
will be damaging wind gusts, although some hail (and even a stray
and brief tornado) cannot be ruled out owing to seasonably
impressive low level shear. The SVR watch currently is set to
expire at 7 pm, but given trends it is certainly possible it may
have to be extended in time a few hours, at least south of I-20.
Flooding was a large concern north of I-20 over the Arklamiss
Delta, but the trend toward forward-propagation (i.e., movement)
is somewhat reducing the threat of at least major flooding.
Thoughts are that the convective cluster should exit the region to
the south/southeast by mid to late evening with a good deal of the
shower and storm ending in its wake.

However, latest expectations are that composite moisture
convergence and advection will increase well upstream (to the
west/northwest) of our region this evening in advance of another
vigorous storm cluster developing toward the Red River Valley.
There is some potential either this cluster, or another batch of
thunderstorms induced by this cluster, will progress east/south
down the re-orienting baroclinic zone and pass in the vicinity of
our northern zones late tonight through tomorrow morning. A
MARGINAL risk of severe thunderstorms was included in the graphics
and HWO to handle this threat, but due to a high degree of
uncertainty in this chaotic convective regime, there is some
chance the threat will be either removed later or even upgraded.

Tomorrow, by midday any storms passing through northern zones
should be largely to our east or lifting to the north, leaving are
region partly cloudy, seasonably breezy, and very humid. High
temperatures getting into the lower 90s (and approaching the mid
90s in a spot or two) should yield heat index value near or
exceeding the century mark over the majority of the area by the
afternoon. Currently thinking heat advisory thresholds will not be
met tomorrow so will continue to just highlight the heat stress in
the graphics and HWO. /BB/

Saturday night through the work week...

The story of the weekend into the work week will be that of
increasing heat and humidity. The upper trough will be to our east,
which will leave zonal flow and/or broad ridging across the area.
With moisture left in place, this will allow for heat stress issues
to begin to be a concern for much of the area on Sunday. In
addition, capping should allow for a decrease in shower/storm
activity. This heat concern will continue through much of the week
for entire area as high pressure will expand west from the Atlantic.
As heights rise, temperatures will also be increasingly warmer with
some locations seeing highs in the mid 90s. This, combined with
dewpoints in the mid 70s, will bring heat indices near 105 degrees.
In some instances, this threshold will be exceeded. Heat advisories
may be likely this week. One caveat to this may be the increased
potential for diurnal showers and storms through the week. For
residents planning outdoor activities, it will be wise to continue
to monitor the potential for higher heat indices through the week.

.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/
