miles northwest of Intersection Alligator Alley And Miami Canal, and
are nearly stationary.

HAZARD...Two inch hail and 60 mph wind gusts.

SOURCE...Radar indicated.

IMPACT...People and animals outdoors will be injured. Expect hail 
         damage to roofs, siding, windows, and vehicles. Expect wind 
         damage to roofs, siding, and trees.

Locations impacted include...
Miccosukee Indian Reservation, Mile Marker 30 On Alligator Alley,

PRECAUTIONARY/PREPAREDNESS ACTIONS...

For your protection move to an interior room on the lowest floor of a
building.

Continuous cloud to ground lightning is occurring with these storms.
Move indoors immediately. Lightning is one of nature's leading
killers. Remember, if you can hear thunder, you are close enough to
be struck by lightning.

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

.KEY MESSAGES...
Updated at 648 PM EDT Sun Jul 12 2026

 - Heat indices between 105-110 expected each day through the
   middle of the week. Take appropriate precautions during
   extended periods outdoors.

 - Drier air over the region will lead to lower rain chances
   across the coastal areas. Isolated showers and storms may
   develop across interior areas each afternoon through the
   beginning of the week.

.SHORT TERM...
(Rest of today through Monday)
Issued at 126 PM EDT Sun Jul 12 2026

The 12z MFL sounding continues to show a pretty dry layer of air
through 600 mb, with a stout inversion remaining late this morning
at 850 mb. Much of this drier air is a result of a Saharan Air Layer
(SAL) plume, currently stretched out over most of South Florida and
the Caribbean. This dust is very apparent both on visible satellite
and with the naked eye, creating pretty hazy conditions and
diminished air quality across much of the region. This dust plume
will also serve to limit convection this afternoon, with the highest
chances of precipitation only about 20 to 30% across portions of
interior and southwest Florida. PWATs are currently between 1.5 to
1.7 inches, which is below average for this time of year.

Mid and low level cloud cover has been steadily diminishing over the
last few hours, which should allow for diurnal heating to
destabilize the environment and temperatures to begin climbing.
South Florida continues to sit under the influence of broad area of
mid level high pressure. The recent sounding sampled 500 mb heights
near 594 dam, which is in the the 90th percentile for this time
of year. Morning cloud cover has kept the hottest temperatures at
bay so far, with only a few isolated locations seeing heat indices
over 105F. Expect temperatures to keep climbing through the mid
afternoon as the mid level cloud deck diminishes, with highs
looking to peak in the mid to upper 90s, and heat indices between
105 to 110 F. As a result, a Heat Advisory is in effect for
Miami- Dade and Broward, but there is also widespread Major
HeatRisk across all metro areas.

With little synoptic forcing, any of the isolated showers or storms
that develop this afternoon will focus along sea-breeze and outflow
boundary collisions. The Storm Prediction Center has included parts
of Glades, Hendry, and Palm Beach counties in a Marginal risk for
severe weather. While there is some better moisture further north,
still suspect that the atmospheric profile is too dry to sustain
strong and mature convection. But in the low chance that a storm
were to get going, the drier air may contribute to an isolated
severe wind gust threat, with DCAPE values near 1000 J/kg. With
stronger easterly flow persisting, the more likely area to see an
isolated shower or will be along the Gulf breeze over interior
and southwest Florida.

A pretty similar scenario is expected for Monday, but the ridge axis
will shift slightly westward, still remaining at around 593 to
594 dam. Similarly, the surface high over the Atlantic will also
creep westward and closer to Florida, which will shift winds more
southerly across the region. The Saharan dust plume will also
spread west and remain across most of the area. However, guidance
is indicating that the the aerosol concentration of dust will
begin to diminish, which may allow for some increased moisture to
filter back into the region. As a result, PoPs will increase
slightly for northern parts of the forecast area, between 35 to
45%. Once again, storms will likely focus along sea-breeze and
outflow boundary collisions over interior Florida. WAA from
southerly flow and less cloud cover could help raise temperatures
another degree or two higher, with widespread highs in the upper
90s. Another round of Heat Advisories will be likely, along with
widespread Major HeatRisk for all urban locations. These
conditions will affect anyone without proper cooling and
hydration.

&&

.LONG TERM...
(Monday night through Saturday)
Issued at 134 AM EDT Sun Jul 12 2026

Drier than average conditions persist through most of the upcoming
work week as a plume of Saharan dust makes its way across the area.A
few showers or storms may manage to develop each afternoon across
interior areas, but rain chances will remain in the 20-30% range
each afternoon with highest chances across interior and SW Florida.
An increase in moisture is expected for next weekend where rain
chances will increase to 30-40%. The main story this week will be
the heat - with afternoon high temperatures in the mid to upper 90s
each day and heat index values ranging between 105-110 degrees. Heat
advisories are possible each afternoon, although this will be
evaluated on a daily basis.

.AVIATION...
(00Z TAFS)
Issued at 648 PM EDT Sun Jul 12 2026

Vicinity storms currently near Palm Beach and Broward terminals,
but all sites are expected to remain VFR. Activity will wane
after sunset and winds will become light and variable.

.MARINE...
Issued at 134 AM EDT Sun Jul 12 2026

Drier conditions expected across local waters heading into early
next week. Moderate east-southeast flow continues to prevail with
wave heights remaining 3 feet or less.
