Area Forecast Discussion...UPDATED

...DANGEROUS HEAT STRESS CONTINUES WITH SEVERE STORMS POSSIBLE...

.UPDATE...
Updated for 18Z aviation discussion

&&

.AVIATION...
18Z TAF discussion:

Thunderstorms will be the main concern at sites through the next
24 hours, especially at GWO/CBM/GTR/HKS/JAN/NMM/MEI. Isolated
strong to severe storms are a threat at GWO/CBM/GTR through this
afternoon while a more widespread threat of potent storms with
gusty winds should build into initially mentioned site this
evening through midnight. Of course frequent lightning, torrential
downpours, and temporary IFR conditions will coincide with any
storms in this axis as well through tonight. Outside of storms,
expect winds to be generally light from the west though southwest
and conditions will be mainly VFR. /BB/

&&

.DISCUSSION...

Morning update discussion:

A lot going on today. First of all, the Heat advisory has been
upgraded to an Excessive Heat Warning, basically along and west of
the Greenwood...to Vicksburg...to just west of Natchez line. In
these areas the consensus of incoming short range model guidance
suggested instead of flirting with heat warning criteria these
areas would hit it hard and certainly warrant the upgrade from the
advisory. Also boosted high temperatures (not just heat index
values) in the western half of zones through the afternoon given
the weight and trends of the latest hi res data.

But there is also the risk of severe storms to deal with today as
the active "northwest flow" pattern continues in the atmospheric
upper levels. Our region got a taste of what this pattern can
deliver late yesterday into the overnight hours as a few potent
thunderstorm clusters rolled south toward I-20 before dissipating.
The juxtaposition of instability and shear will generally be even
more impressive later today than it was yesterday (when deep layer
wind shear values were on the order of 30 knots with surface based
CAPE values peaking over 5000 j/kg). Already some potent
convection has gotten going in eastern AR, although very recent
trends show weakening and reluctance to exhibit worrisome forward-
propagation. Outflow coming out from these storms could spark at
least isolated storms in northern zones through the afternoon, but
the main risk of severe weather in our region will come very late
this afternoon through around midnight as a solid squall line
develops to our north and races south/southeast. Widespread
damaging winds will be the main concern, especially in
northeastern third of the forecast area where confidence of impact
is increasing. Elsewhere in the forecast area, roughly along and
southwest of the Highway 49 corridor, the potential of impact
falls off greatly with southwest extent.

Updates to the HWO and graphics are ongoing and we will continue
to update products as we go through the afternoon and can refine
thinking on timing and level of impact. /BB/

Prior discussion below:

Today and Tonight...Isolated storms will remain possible as day
breaks across the ArkLaMiss this morning as a couple of outflow
boundaries, one over East Central Mississippi and the other moving
into Southeast Mississippi, slow their southeast progression.  With
high pressure aloft building deeper into the region today from the
west and the aforementioned slowing boundaries, it'll be primarily
over East and Southeast Mississippi where the better rain chances
will reside this afternoon.

Although high-res models agree with this scenario today, they
haven't exactly performed stellar over the past 48 hours.  So,
attention to radar and satellite will need to be paid upstream under
this continued northwest flow for any MCS or outflow activity that
could propagate southeast into the region, potentially initiating a
better coverage of convection during the today period.

Speaking of northwest flow and MCSs, global and high-res models are
in good agreement with a potentially stout affecting mainly the
eastern half of the CWA during the overnight hours.  With plenty of
instability hanging on overnight in this warm and moist airmass,
steep mid-level lapse rates, and adequate deep-layer wind shear,
some severe storms will be possible with this complex as it affects
the area later tonight.  Currently, the better potential for severe
storms will reside along and northeast of a Greenville to Meridian
line, where a "Slight Risk" for severe storms exists.  A narrow
"Marginal Risk" area reside outside the "Slight Risk" are from
Hamburg, AR, to Jackson, to Laurel.  Isolated severe storms are
possible within this "Marginal Risk" area.  Severe storms will be
capable of producing damaging wind gusts and large hail.  In
addition, nearly continuous lightning and torrential rainfall can be
expected as will with this complex as well.

Before we get to the severe weather threat for tonight, dangerously
high levels of heat stress will continue today.  Afternoon highs
ranging from the mid 90s to around 100, coupled with dew points in
the 70s, will again promote afternoon heat index values between 105-
110, especially across the Delta region.  As a result, another "Heat
Advisory" has been hoisted for today from 11 AM until 8 PM.  If
either temperatures or dew points run higher than what's currently
being forecast this afternoon, portions of this "Heat Advisory" may
need to be escalated to an "Excessive Heat Warning".  Lows
tonight will again remain mild, and fall into the 70s. /19/

Saturday through Thursday: The primary concerns will be heat stress
and rain chances through the period.

The period will be characterized by anomalous mid to upper ridging
west to mid to upper troughing over eastern conus. This will bring
northwest flow to the region during the period. The ridging will
contract some toward the west on Saturday as upper troughing becomes
dominate from the north. Meanwhile anomalous low to midlevel temps
will continue on Saturday but will decrease on Sunday. This will
result in highs in the middle to upper 90s with some triple digit
numbers west of the MS River on Saturday. This will bring heat
indices from the around 105 to 113. The warmest indices will be over
the western areas mainly Saturday,which will decrease in coverage on
Sunday. So will maintain the heat risk in the HWO for Friday through
Sunday. Models indicate that some strong storms will be possible on
Saturday into Saturday night with northwest flow aloft. We will have
0-3km winds of around 35 knots, Vertical totals in the lower 30s in
the north,a frontal passage for lift, and good lapse rates. CAM
guidance shows a good line passing in the TN valley to the north and
east , along with isolated activity across our area. SPC has a
marginal risk for our eastern areas, since we have a severe risk for
today will hold off on that for the graphics for now. As we push
through the weekend the axis of the upper trough will spread over
the remainder of the region by Sunday. An associated upper low will
with another frontal boundary will push south across the Lower
Mississippi Valley On Wednesday. The weak closed low will wash out
over the SE Conus as upper flat ridging takes over. This will keep
rain chances across the region for the upcoming workweek with our
soupy airmass.

As far as temperatures are concern beyond this weekend with the
frontal passage readings will tone back to mainly from the upper 80s
to the lower 90s. Lows will be in the lower to middle 70s./17/
