.MESOSCALE UPDATE...
Issued at 219 PM CDT Wed Jun 24 2026

Rest of today into tonight...

A cloudy and less humid afternoon is on tap, with rain and storms
ongoing across the region. A few showers and storms are migrating
southeast this morning, leading to widespread cloud coverage
across a majority of the region. There are also a few mesoscale
convective vortices (MCV) around, with one evident moving across
northern Lauderdale County. We remain on the northern fringe of a
stationary frontal boundary, with better moisture and
destabilization along and southwest of the stationary front. This
is generally over southwest MS into southern portions LA. This is
leading to a good temperature gradient of mid 80s into central LA
to southeast MS while only in the upper 70s to low 80s to the
north under the cloud shield. There is is some bulk shear across
the area, so the inherited Marginal Risk is valid. There was an
earlier expansion and cannot rule out some strong storms or a
couple of severe storms as well. Morning microburst checklist,
including 12Z sounding modified to reflect the near storm
environment (NSE) this afternoon, is generally little risk in
central MS while some low but more supportive into central LA and
southwest MS. There are a few convective allowing models that
indicate some potential organization of north to south oriented
storms, which would favorably align for convective wind gusts and
possibly some hail. This is most likely south of Interstate 20
into Highway 84 but cannot be ruled out even further north. In
addition, there remains a low risk of heavy downpours up to 3
inches, possibly locally higher. Kept the inherited Limited for
flash flooding to reflect the earlier expansion to the Marginal
risk for severe in the HWO graphics. Most organized storms or
flash flooding threats will wind down into early evening (9PM to
10PM). HREF and REFS dense fog probabilities indicate some
potential into northeast MS and an HWO graphic was advertised for
those local areas.

For forecast elements, temperatures will be seasonably cool along
and north of Interstate 20, some 3F to 6F degrees below (82F to
86F), while seasonable to the south (88F to 92F). Rain chances
will remain high (50 to 90 percent range), with highest focused in
northern half of the area. Some overnight rain chances will
persist in southern half of the region tonight, and cannot rule
out another round moving back into the northwest late overnight.
Seasonable lows are expected as well. Updates are out. /DC/

.DISCUSSION...
Issued at 219 PM CDT Wed Jun 24 2026

Thursday through next Tuesday:

Northwest flow and active convective pattern will continue through
Thursday before warmth and heat build in late week through the
weekend. Shortwave trough will dig through the region leading to
continued scattered convective activity into Thursday.
Precipitable water (PWs) will remain generally the same (1.8 to
2.0 inches) so scattered coverage (20 to 45 percent) will be the
norm. There should be some lapse rates (24C to 26C vertical
totals) and light northwesterly shear (10 to 15kts) so cannot rule
out a rogue strong storm. Highs will moderate a little more
seasonable (upper 80s to low 90s to the south). Humidity will
creep up somewhat as well, with heat indices peaking into the
upper 90s to low 100s, especially in the south.

Mean ridging at the surface and aloft will build in Friday through
the weekend, leading to dry weather into the weekend. Deepening
ridge (594 to 596DM) and warm advection will drive summertime warmth
and humidity back into the region. Highs will moderate (3F to 6F
above Friday to Sunday and 4F to 8F above early next week),
generally low to mid 90s Friday into Sunday and mid to upper 90s
next Monday and Tuesday. Dangerous heat will become a concern
through that period, especially Saturday and beyond as heat
indices near or in excess of 105F degrees to even in excess of
110F degrees at times. HWO graphics and heat headlines will likely
be needed in later forecast during this stretch of dangerous
heat. Lows remain seasonably warm during this time (low to mid
70s). Next best chance of rain may not be until mid next week
(earliest reasonable next Tuesday with most likely next
Wednesday). /DC/

.AVIATION...
(18Z TAFS)
Issued at 219 PM CDT Wed Jun 24 2026

SHRA and TSRA will continue this afternoon, which could bring
periods of gusty winds and variable visibility, persisting through
around 25/00Z Thursday. SHRA and occasional TSRA cannot be ruled
out overnight. Lowered flight restrictions are possible overnight,
generally near GTR and MEI, as low as IFR to LIFR ceilings and
IFR visibility, with occasional MVFR ceilings at JAN and HKS.
Lowered flight restrictions should improve by 25/15-16Z Thursday,
with SHRA and TSRA chances generally increasing after the end of
the 18Z TAF cycle. /DC/NF/
