...SIGNIFICANT SEVERE WEATHER EVENT LIKELY THURSDAY...

.UPDATE...
Updated for 00Z aviation discussion

.AVIATION...
00Z TAF discussion:

Expect deteriorating conditions this evening as stratus lowers and
shra/tsra increase in association with a northward moving warm
front. IFR/MVFR category stratus will be widespread from late
night through the morning, but precip coverage will diminish
during that time as the warm front shifts north of the area. By
late Thu morning, stratus will break up some and lift, then expect
isolated +TSRA during the afternoon, mainly from JAN/HKS to GWO
and eastward from there. Southerly winds will be quite strong and
gusty and LLWS will be a concern especially during the predawn to
shortly after daybreak time frame. /EC/

.DISCUSSION...
Tonight through Thursday Evening...The primary story through the
short-term remains the significant severe weather potential on
Thursday. Before we get to that though, we have another potential
bump in the road, per say, on the way to Thursday's event.  This,
coming in the form of a potential for severe storms late this
afternoon into late tonight.

Southwest flow aloft across the region will persist. A compact but
stout mid/upper level trough digging southeast from the Four Corners
region into the southern plains states, will eject northeast across
the Ozarks into the Mid-Mississippi River Valley on Thursday.  As
this happens, a boundary currently residing to the south of the CWA,
will begin lifting northward as a warm front. As this happens,
surface moisture will rush in and begin overspreading the CWA from
the south, with dew points climbing into the 60s in most areas
tonight, with dew points in the 70s on Thursday.

Showers and storms will develop across the CWA along the warm front,
as well as in the front's wake through the evening. As both
instability and wind shear across the region during this time, in
addition to steepening mid-level lapse rates, isolated severe storms
will be possible now through into late tonight across much of the
CWA. However, the best chance for severe storms still looks best
across the northwest portion of the CWA. Currently, hail to the size
of quarters and damaging wind gusts will be the primary concerns
with storms, but a tornado cannot be ruled out. Otherwise for today,
look for mostly cloudy skies with highs in the mid and upper 70s.

As the warm front continues to lift northward into the the Mid-South
region through early Thursday morning, the threat of severe storms
will grow less across the CWA.  This is a result of warming aloft
across our region. However, some scattered showers and storms will
remain possible through the rest of the overnight hours into
Thursday morning. Otherwise, look for muggy breezy conditions by day
break Thursday, with lows into the low to middle 60s.

As day breaks on Thursday, a lull in convection is expected across
the CWA.  Gusty southerly winds across the CWA will continue to
increase instability levels across the forecast area through mid-
day.  Overall, conditions Thursday will be be very muggy as highs
climb up into the mid 70s to around 80 early in the afternoon.

As the aforementioned mid/upper trough pivots northeast from the
southern plains towards the Mid-Mississippi River valley late
Thursday morning, it'll send a pre-frontal trough into the CWA by
mid-day.  This pre-frontal trough, in addition to ample and still
increasing levels of both instability, wind shear, and very steep
mid-level lapse rates across the region, will be the spark needed to
begin igniting convection across the forecast area around noon
Thursday, and continuing into early Thursday evening afternoon in
the Golden Triangle area.

Severe storms will be possible across the entire forecast area
Thursday. However, current high-res model trends continue to suggest
the area of best threat for the most intense and destructive fast-
moving super cells, will reside over the area mainly along and
northeast of a Grenada to Jackson to Meridian line.  It'll be here
that the best conglomeration of peak severe parameters in afternoon
heating are expected. Regardless, in the most intense storms,
tornadoes will be likely, with some of those tornadoes potentially
being strong and long-tracked. Damaging winds up to 80 mph and hail
greater than golf ball size are also possible. Further south, again
severe storms are possible, but a capping inversion looks to make
convection a bit tougher to come by.  Hence, why a tighter gradient
exists in SPC's severe category threat across the southern portion
of the CWA.  In addition, an additional one to three inches of on
top of rain from previous days, could result in the some localized
flash flooding and continued river flooding, especially across the
Pine Belt this evening through Thursday.

Residents across the CWA, and well as the Deep South in general,
need to actively monitor NOAA Weather Radio, along with local radio
and television stations throughout the day Thursday, to keep abreast
of the latest weather and watch/warning information.  Please have a
plan of action in place ahead of time, so in the event a warning is
issued for your county or parish, you know where to go immediately.

Storms will exit the CWA in the early evening hours.  Winds will
remain breezy in the wake of the storms, with mostly sunny skies
expected over much of the forecast by late evening.  Drier air will
also begin moving into the area, as dew points fall into the 50s
from west to east through the evening. /19/

Thursday night through Saturday...The period begins with the
cold front and preceding severe threat exiting east and rain
chances moving out of the area and stalling near the northern Gulf
coast. Cooler, drier air filters in Thursday night and
temperatures are likely to fall into the 50s F across the
Arklamiss with a few upper 40s F for overnight lows possible in
some of the typically colder spots. The stalled front will begin
moving north as a warm front into southern Mississippi by Friday
midday. Temperatures rebound quickly Friday, into the 70s to near
80 F from north to south. A more significant difference apparent
temperature is likely with lower 50s F dewpoints in the north
compared to a much more muggy 60s south of the weakly northward
moving warm front.

By Friday evening and overnight, a few showers are possible in the
vicinity of the frontal boundary. However, with little in the way of
upper level support, only isolated rain showers or brief
thunderstorms are expected for most north of I-20. A stronger storm
is possible along and north of the hwy 82 corridor where the Storm
Prediction Center has outlooked a "Marginal" risk for severe storms.
Given the uncertainty following the impending midweek severe and how
it may affect the severe storms risk by late week, we are currently
not highlighting a defined risk area. As we move closer in time to
the possible risk, a risk area may need to be delineated. Chances of
precipitation increases some on Saturday mostly along and north of I-
20. Some heavy rain and thunderstorms are possible, particularly
along and north of the Hwy 82 corridor. Some in this zone of heavier
rainfall may see 1-2" where storms move across the same areas. Highs
Saturday will reach into the lower and middle 80s F for most, held
into the 70s F by rain and cloud cover in the north.

Saturday evening through Tuesday...Saturday evening into early
Sunday morning, a weak upper disturbance with attendant weak
surface low will likely be moving eastward across the Middle
Mississippi Valley region and will push the frontal boundary back
south. Scattered thunderstorms with some possibly strong to severe
are likely as the front moves south into an environment
characterized by some guidance of around 750-1000 J/KG SBCAPE,
50-55 kt 0-H5 bulk shear, dew points in the middle to upper 60s F,
and around 200 0-1 km SRH. By 09z early Sunday, GFS forecast
soundings indicate increasing CINH with an inversion developing
around 900 mb as well as increasingly veered boundary layer flow.
This will likely result in a weakening trend for storms during
this time. Even so, some remaining elevated instability and the
lift associated with the advancing cold frontal boundary will
likely contribute to continued showers and storms moving in a band
from north to south.

Rain chances diminish by Sunday afternoon as the front moves south
of the area. Highs cool a bit from Saturday, rising into the 70s
across the area. A cooler night follows with middle 50s F for most
and upper 40s F likely for northern areas. Not unusual for this time
of year, the front once again stalls near the northern Gulf coast.
By Monday, the front begins to move north as a warm front. Forecast
soundings indicate defined veering with height along and near the
front and the associated warm air advection and southerly flow
moving atop the slowly advancing warm front will contribute to
showers and storms. This area of precipitation will be moving slowly
north during the day Monday. With only very weak southerlies on the
western flank of the subtropical high aiding in the frontal
progression, its progress nay become stalled across the area and
rain chances are likely to continue into Tuesday. /86/
