  approaching from the northwest mainly for the afternoon/evening
  hours today and possibly again Thursday, with greater
  focus/confidence for areas east of I-55, including coastal
  Mississippi and adjacent marine waters.

- Strong heat will be back with heat index readings up to 110F
  starting Sunday into the new workweek with heat advisories
  becoming increasingly likely this weekend and into early next
  week.

.SHORT TERM...
(Now through Saturday)
Issued at 1114 AM CDT Wed Jun 24 2026

Aloft, northwest flow continues over the region, which is usually
a pretty good signal for MCS activity and, indeed, upstream there
have been a few areas of storms develop. In additional to a series
of H5 impulses, there resides a weak frontal boundary from the
Red River Valley to the northeast Gulf. This has been and will be
enough to generate additional storm activity. At this juncture,
this afternoon looking at overall trends favors south MS including
the MS Gulf Coast. This is were both WPC places a slight ERO and
SPC put a marginal for severe. The LIX 24/12z RAOB showed a
favorable DCAPE (generally greater than 1000 J/KG), which
signifies at least a conditional risk for strong damaging wind
gusts in the wider and more robust updrafts.

Late Thursday and into Friday a pattern shift will occur with the
story becoming less about potential convection and more about
increasing temperatures and humidity. An upper level ridge
develops over the northern Gulf and moves gradually over our
region building from around 590dam to 594dam. With more subsidence
and less of a surface convergent zone outside of diurnal
boundaries, convection will be tough to find beyond Friday with
highs warming well above climo across the board. (Frye)

.LONG TERM...
(Saturday night through Tuesday)
Issued at 1114 AM CDT Wed Jun 24 2026

Going later into the weekend and early next week it's going to be
hot with above average temperatures as a strong ~596dam ridge
builds over the gulf coast states allowing afternoon temperatures
to soar. With still wet grounds, the humidity will cause a problem
with likely heat headlines needed through much of the long term
afternoon hours. The upper ridge late Monday or Tuesday will
refocus over the Mid MS River Valley. This will also for at least
some slight weakness in the mid and upper levels. Coupled with the
diurnal cycle, shower and storms chances will begin to creep up
little by little Tuesday afternoon and evening. Otherwise, again
the primary focus in the long range will be the potentially
dangerous heat. (Frye)

&&

.AVIATION...
(18Z TAFS)
Issued at 1114 AM CDT Wed Jun 24 2026

Mostly VFR/MVFR conditions through the period. Cannot rule out
some convection north of I10/12, but GPT and MCB have the best
potential...with convection there can be brief lowering CIGs/VIS
in the heavier showers and storms. Any activity should weak around
or shortly after sunset. Winds outside of showers and storms will
remain light and variable, but start to favor a west or southwest
direction. (Frye)

&&

.MARINE...
Issued at 1114 AM CDT Wed Jun 24 2026

Surface high pressure over the central gulf will continue to promote
weak, mainly westerly flow today. The high will move east bringing
onshore flow back to the coastal waters late Thursday, which will
remain through the weekend. A series of thunderstorm complexes will
surge southeast along a stationary inland front through Thursday,
causing strong erratic winds in and near these storms as they move
offshore. Conditions dry out toward the weekend and winds weaken to
light and variable as high pressure moves over the north central
gulf. (Frye)

of Pearlington, or 8 miles southwest of Waveland, moving southeast at
10 mph.

HAZARD...Waterspouts and winds in excess of 40 mph.

SOURCE...Radar indicated.

IMPACT...Waterspouts can easily overturn boats and create locally
         hazardous waters. Gusty winds could knock down tree limbs
         and blow around unsecured objects.

This storm will remain over mainly rural areas of south central
Hancock County.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If outdoors, consider seeking shelter inside a building.

At 111 PM CDT, Doppler radar was tracking a cluster of strong
thunderstorms capable of producing funnel clouds and waterspouts near
Shell Beach, or 19 miles north of Port Sulphur, moving southeast at
15 mph.

HAZARD...Waterspouts and funnel clouds and winds in excess of 40
         mph.

SOURCE...Radar indicated.

IMPACT...Waterspouts can easily overturn boats and create locally
         hazardous waters. If a funnel cloud briefly touches down,
         minor damage to outdoor objects is possible. Gusty winds
         could knock down tree limbs and blow around unsecured
         objects.

Locations impacted include...
New Orleans, Chalmette, Harvey, Timberlane, Belle Chasse, Gretna,
Violet, Terrytown, Meraux, Poydras, Shell Beach, Arabi, and Woodmere.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If outdoors, consider seeking shelter inside a building.

Conditions are favorable for the development of weak, brief funnel
clouds. This type of funnel cloud is harmless, but on rare occasions
they can briefly touch down, producing wind gusts over 50 mph. If a
funnel cloud is spotted move indoors or to safe harbor and report
your sighting to the National Weather Service.

Torrential rainfall is also occurring with these storms and may lead
to localized flooding. Do not drive your vehicle through flooded
roadways.

If on or near marine areas, get out of the water and move indoors or
inside a vehicle. Remember, lightning can strike out to 10 miles from
the parent thunderstorm. If you can hear thunder, you are close
enough to be struck by lightning. Move to safe shelter now! Do not be
caught on the water in a thunderstorm.
