.NEAR TERM...
(Through Thursday)
Issued at 229 PM EDT Wed Jul 16 2025

The tropical low known as Invest AL93 is moving west this
afternoon just offshore the Emerald Coast. It will not develop
into a tropical depression before getting well west of our
forecast area, if at all. Nonetheless, we will be on its eastern
flank through Thursday. So regardless of development, we will be
in deep southerly flow, and the air mass will remain very moist.
PW values of 2+ inches will be common.

Quite a few showers and thunderstorms are dotting the region this
afternoon, and most places are getting at least a few passing
showers this afternoon. With tropical rain processes in play and
respectable moisture transport, rainfall rates can be impressive,
even in lower-topped convective cells. Where you get higher-topped
convection, torrential rainfall rates can be expected. If cells
start to line up in more solid confluent or curved bands, then
flooding would become a concern.

So look for ongoing convection to fade quickly late this afternoon
and early this evening, as convection works over the inland air
mass. Convection will reignite late tonight and on Thursday
morning over the bathwater-warm Gulf waters. Quick southerly flow
will push convection onshore and into coastal communities well
before sunrise. Convection will start to spread further inland as
soon as we pass sunrise, spreading north of the FL state line by
late morning.

Over the next 24-30 hours, 1 to 3 inches of rain will be common,
with the I-75 corridor in Georgia being the driest. If convection
trains onto the coast, then expect a quick 4 to 6 inches of rain
somewhere in our FL counties. These higher amounts would bring
isolated flash flooding. Lesser amounts could still bring less
serious nuisance flooding and ponding on roadways.

.SHORT TERM...
(Thursday night through Friday night)
Issued at 229 PM EDT Wed Jul 16 2025

The area of low pressure over the Gulf will have moved westward out
of our waters and an upper level ridge will be building to our east.
The Bermuda high, also to our east, will continue with southerly
flow for the short term. During the day Friday, showers and
thunderstorms will likely develop in the afternoon hours along the
sea breeze. PWATs will be around 2 inches, so heavy downpours will
be possible with any storms. PoPs for Friday range from 60-80
percent, with highest chances along and south of I-10. Temperatures
on Friday will be subdued from the rain and clouds, with highs in
the mid-90s and heat indices should remain below advisory criteria.
Overnight lows will be in the mid-70s.

.LONG TERM...
(Saturday through Tuesday)
Issued at 229 PM EDT Wed Jul 16 2025

High pressure will continue to build over the weekend into the start
of next week. Temperatures will be gradually increasing while PoPs
values will gradually decrease. However, PoPs will become more
diurnally driven with the afternoon sea breeze. Warming
temperatures will bring back heat advisories for this weekend
through next week, but we will be monitoring based on how much
mixing is expected during the afternoon. Temperatures will be in the
upper 90s for the highs, and mid-70s for the overnight lows. PoPs
this weekend range from 30-50 percent, then increase to around 50-70
percent for the start of the work week as PWATs increase with added
tropical moisture moving in from the East Coast.

.AVIATION...
(18Z TAFS)
Issued at 229 PM EDT Wed Jul 16 2025

Deep layer southerly flow will prevail for the next 24 hours, to
the east of a low that will be moving toward the north-central
Gulf. This will keep the air mass very moist. Quite a few showers
and thunderstorms are spotting the region this afternoon. They
should diminish late this afternoon and evening. Storms will
rebuild over the Gulf waters tonight, spreading onto the coast
before sunrise, then spreading inland during the course of the
morning. So the mention of thunder in the TAFs is fashioned after
these trends, with TEMPO groups indicating highest confidence
periods for thunder.

.MARINE...
Issued at 229 PM EDT Wed Jul 16 2025

Southerly breezes will increase over the waters tonight, becoming
fresh on Thursday morning as we get squeezed between departing low
pressure to our west and high pressure east of Florida. The
summertime Bermuda ridge axis will expand westward on Friday and
Saturday across the Florida Peninsula and into the eastern Gulf,
persisting through Monday.

&&

.FIRE WEATHER...
Issued at 229 PM EDT Wed Jul 16 2025

A seasonably moist and unstable air mass will continue for the
foreseeable future. Areas of high dispersion are expected on
Thursday afternoon due to enhanced southerly transport winds. A
warming trend will get underway on Friday, with much above normal
temperatures starting Saturday.

&&

.HYDROLOGY...
Issued at 229 PM EDT Wed Jul 16 2025

Isolated flash flooding will be a concern through Friday, mainly
over our FL counties.

Over the next 24-30 hours, 1 to 3 inches of rain will be common,
with the I-75 corridor in Georgia being the driest. If convection
trains onto the coast, then expect a quick 4 to 6 inches of rain
somewhere in our FL counties. These higher amounts would bring
isolated flash flooding. Lesser amounts could still bring less
serious nuisance flooding and ponding on roadways.

Thunderstorm coverage will decrease over the weekend, then build
during the first half of next week. Most any summer thunderstorm
is capable of intense rainfall rates that can lead to short-lived
nuisance flooding.
