An area of weak low pressure has developed over the Gulf Stream
off the east coast of FL today. This low will enhance ENE flow
shifting the Atlantic sea breeze further inland this afternoon.
The late start to convection today has allowed for temperatures to
soar into the low to upper 90s and heat indices approaching Heat
Adv criteria. High DCAPE over our inland areas and a moist
airmass (PWATs ~ 2 in) will promote some stronger wet microbursts
with gusty winds to 40-60 mph possible and localized flooding. The
best chance for isolated strong/severe storms will be mainly
where the sea breezes collide between US 301 and I-75 corridors
late this afternoon into evening. The low will gradually shift
westward toward central/north-central FL tonight into early
Tuesday morning. Overnight lows will be in the 70s.

.SHORT TERM...
(Tuesday through Wednesday night)
Issued at 226 PM EDT Mon Jul 14 2025

Low pressure over the area Tuesday will shift to the west
Wednesday out into the northern Gulf. PWAT values over the area
will be highest over northeast Florida and along the coast by the
afternoon, providing enough moisture for localized heavy rainfall.
Winds coming in off the Atlantic will help push afternoon sea-
breeze convergence towards I-75 where a few stronger storms could
start to develop in the afternoon and evening time frame. High
daytime temperatures will be a few degrees cooler than previous
days, with temperatures in the low to mid 90s over southeast
Georgia and upper 80s to low 90s over northeast Florida. Overnight
temperatures will be in the low to mid 70s area wide, staying
slightly warmer in coastal areas.

&&

.LONG TERM...
(Thursday through next Monday)
Issued at 226 PM EDT Mon Jul 14 2025

High pressure builds in from the east and sticks around through
the end of the period as low pressure in the Gulf moves further
west. Plenty of moisture over the area and diurnal heating with
winds mostly from a southerly direction will help continue the
afternoon rain and storms trend. Temperatures will slowly increase
into the weekend with temperatures above the seasonal average.

&&

.AVIATION...
(18Z TAFS)
Issued at 226 PM EDT Mon Jul 14 2025

Isolated showers and storms have begun to develop along the
Atlantic sea breeze currently over JAX. Winds have shifted to ENE
for coastal TAF sites at around 10 kts. The sea breezes will
continue to shift inland and likely collide between US 301 and I75
corridors. Have TEMPOs in for stronger storms between 18-23Z for breezy
winds, MVFR CIGS and possible IFR VSBYS with heavy rainfall. Rainfall
chances fade after sunset (00Z) and will leave VFR conds with
lingering clouds through the end of the TAF period.

.MARINE...
Issued at 226 PM EDT Mon Jul 14 2025

A weak area of low pressure has developed over the Gulf Stream today
and slowly shifts westward into the coastal waters tonight. Showers
and thunderstorms will then increase in coverage on Tuesday and
Wednesday as the low shifts westward across the Florida peninsula
and into the eastern Gulf, with low pressure potentially strengthening
later in the week near the northern Gulf coast. NHC has highlighted
the northern Gulf coast for a low chance of tropical/subtropical
development for this week. Prevailing northeasterly winds today
will shift to southerly by late Tuesday as the low shifts west of
our local waters, with south- southeasterly winds briefly
strengthening to Caution levels near shore on Wednesday afternoon.
Rounds of showers and thunderstorms will continue through late in
the week as southerly winds prevail.

Rip Currents: Moderate risk of rips with surf/breakers of 1-2 ft
today. Threat begins to increase Tuesday into mid-week as flow
slowly becomes more onshore.
