.MESOSCALE UPDATE...
Issued at 856 PM CDT Mon Aug 11 2025

Rest of Tonight...An overall quiet night is expected across the
forecast area tonight.  Increasing moisture, particularly across
southern & eastern portions of the area, could yield some clouds
across these areas, along with an isolated shower over mainly
southern parts of the area early Tuesday morning.  Otherwise, look
for mostly clear north to partly cloudy skies south and east
overnight with lows falling into the middle 70s.

The ongoing forecast is in good shape.  Other than some minor
adjustments to hourly elements of the forecast based on trends, no
major changes will be made on this evening`s update. /19/

.DISCUSSION...
Issued at 1243 PM CDT Mon Aug 11 2025

Tonight through Tuesday...

Rain chances will diminish across much of our forecast heading into
the evening hours with a slight chance of scattered showers and t-
storms mainly for areas along and south of the I-20 corridor. The
heat advisory for portions of northeast LA, central MS, southwest
MS, and west central MS remains in effect until 7 PM this evening.
Quiet conditions will occur across our CWA heading into the
overnight period thanks to broad ridging over our area. Sky
conditions will remain generally cloudy across our area as clouds
continue to build from the east. Expect overnight lows to drop into
the low to mid 70s areawide.

Early Tuesday morning will start off relatively quiet across most
of our CWA with a slight chance of a pop-up shower across the Pine
Belt. Rain showers/t-storms chances will start to increase heading
into early Tuesday afternoon/late Tuesday evening as near term
guidance shows easterly moist boundary layer advection across our
forecast area. Southeast and east portions of our CWA will have a
better chance of seeing afternoon convection with PoPs around
65-70%. A few isolated strong storms with wind gusts up to 40 mph
cannot be ruled out.

In addition to the rain chances, increasing moisture will lead to
increasing heat stress across much of our forecast area. This
combined with afternoon highs in the low to mid 90s will lead to
peak heat index values between 105F and 110F mainly for areas along
and west of I-55. Several areas along and west of the MS River will
have the best potential to see "Elevated" heat stress with heat
index readings around 110F. A heat advisory will likely be needed
for these areas for Tuesday. No changes have been made to the heat
graphic for Tuesday and a "Limited" risk for increasing heat stress
will continue to be advertised. /CR/

The forecast for the extended period remains on track with no
significant changes made to the overall forecast. Dangerous heat
stress will continue to be the primary focus. No changes have been
made to the heat graphic for the late week. Please see the previous
forecast discussion for more details:

Wednesday through the weekend...

The area will continue to be under broad ridging through most of the
week, which will gradually build, peaking by week`s end. The
increase in moisture along its western flank will increase rain
chances across the area mid week, with highest chances focused in
the southeast. As the ridge shifts westward by the weekend, rain
chances will decrease and heat will increase. Heat headlines may be
eventually need to be expanded to cover more portions of the area as
heat indices climb to the 105-110 range. Next week, a tropical
system moving up near the eastern sea board will likely break the
heat as drier northerlies become established. There could be a
backdoor front associated with the system that could break the heat
even sooner for our east, but there is still uncertainty regarding
how far offshore in the Atlantic the tropical system will be. This
system does not look to impact our area, in fact we probably stand
to benefit. /CR/

.AVIATION...
(00Z TAFS)
Issued at 620 PM CDT Mon Aug 11 2025

VFR flight categories will prevail at most area TAF sites through
much of this 00Z forecast period. Winds will subside this
evening, remaining calm to light from the east southeast around 3
knots overnight. Toward day break Tuesday, some low stratus will
be possible at namely KGTR, KMEI, KPIB, & KHBG reducing categories
at these sites to MVFR/IFR categories for few hours. Ceilings are
forecast to improve to VFR categories there by 17Z. Winds will
increase from the southeast around 5-8 knots Tuesday afternoon,
with convection developing across mainly east and southeast
Mississippi during the heat of the afternoon. /19/
