UPDATE
Issued at 708 PM EDT Thu Jun 19 2025
For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf
Evening convection across SE GA and portions of the Suwannee River Valley ahead of a pre-frontal trough will continue to decrease in coverage and intensity through 10 pm as daytime instability wanes, however, cannot completely rule-out a rouge shower or isolated storms especially after midnight across the Suwannee River Valley south of the I-10 corridor where Gulf instability noses inland just head of the front and could fuel some early morning convection. Otherwise, mostly dry elsewhere with decreasing cloudiness across SE GA toward daybreak where some shallow patchy ground fog is possible while lingering debris clouds continue across NE FL tonight keeping fog potential lower. Mild and muggy overnight lows will range in the 70s.
AVIATION
(00Z TAFS)
Issued at 708 PM EDT Thu Jun 19 2025
Sea breeze shower and storm risk has generally ended at all NE FL terminals, but with pre-frontal convection sliding southward this evening from SE GA, cannot rule-out a rouge shower or lone storm and will handle with TEMPO groups as needed based on radar trends.
This potential is generally 15-20% for NE FL terminals through 06z. Best potential of near-term TS or SHRA (30-40%) through 06z will be at SSI and will continue to monitor radar with inclusion of TEMPO group as needed. After 06z, potential for rainfall tappers off as multi-layered cloudiness lingers across the terminals tonight as the pre-frontal trough lingers across the region. A return of afternoon showers and storms expected again Friday along both east and west coast sea breezes, with higher chances (50-70%) of TS across NE FL terminals supporting VCTS after 18z and will leave out TS for SSI at this time (rain chances < 30%).
MARINE
Issued at 708 PM EDT Thu Jun 19 2025
High pressure over the Atlantic will extend across south Florida through Friday as a front slides southward across the region and gradually dissipates through Saturday. Scattered showers and storms are expected each day. High pressure builds northward this weekend, with easterly winds over the local waters early next week with decreasing thunderstorm chances over the local waters.
Rip Currents: Generally, a low risk of rip currents is expected each day through Saturday but the daily east coast sea breeze will bring a slight uptick in rip current potential each afternoon and early evening.
