.KEY MESSAGES...

- Hot conditions continue this afternoon, with near record high
  temperatures and heat index values of up to 110.

- There is a marginal risk of severe thunderstorms this afternoon,
  with a few strong or damaging storms possible.

.DISCUSSION...
Issued at 138 PM EDT Fri Jul 10 2026

The Saharan Air Layer still lingers, though seems to have thinned
out compared to yesterday. Even with the SAL still present,
afternoon thunderstorms are still expected to develop especially
for coastal areas, south of I4. Warm temperatures, plenty of
surface moisture, and moderate instability could lead to isolated
strong or severe storms. Main concern will be strong, damaging
winds. Otherwise, the main story continues to be the heat . High
temperatures are expected to be near record for many places once
again and wide spread heat indices over 100 with some reaching
around 108 or higher.

As typical moisture returns to the area this weekend, temperatures
will moderate slightly, though still reach the low to mid 90s each
day. Current forecast shows the Saharan dust returning over South
Florida by Sunday then lingering through the first half of the week.
However, rain chances will increase for the northern half of the
forecast area where moisture will be increasing a frontal boundary
approaches.

&&

.AVIATION...
(18Z TAFS)
Issued at 138 PM EDT Fri Jul 10 2026

VFR conditions prevail. However, scattered to numerous storms are
expected to develop later this afternoon into the evening,
especially over SWFL. Some storms could have strong, damaging winds.
Conditions quiet overnight.

&&

.MARINE...
Issued at 138 PM EDT Fri Jul 10 2026

Marine conditions will continue to be quiet through the weekend as
winds stay below 10 kts. Only concern will be showers and storms
that move over the water creating locally higher winds and rough
seas.

&&

.FIRE WEATHER...
Issued at 138 PM EDT Fri Jul 10 2026

Fire weather concerns remain minimal as plenty of low level moisture
remains in the area. Scattered to numerous showers and storms
expected this afternoon into the evening, mainly south of I4.
