AVIATION
(06Z TAFS)
Issued at 202 AM EDT Fri Apr 26 2024

VFR conditions will prevail at the regional terminals. Periods of scattered to broken stratocumulus ceilings of 5,000-6,000 feet are expected through Friday evening. An easterly wind surge on Friday afternoon and evening could advect a few light showers or sprinkles towards the SGJ terminal, but confidence was too low to include in the TAFs at this time. Light winds overnight will shift to easterly by 16Z, with sustained surface speeds increasing to around 15 knots at the SSI and SGJ coastal terminals, CRG, and JAX by 20Z, with speeds elsewhere increasing to 10-15 knots. Easterly surface winds will then subside to 5-10 knots by 01Z Saturday at the inland terminals, while sustained speeds remain around 10 knots at the coastal terminals through the overnight hours on Friday night.

UPDATE
Issued at 705 PM EDT Thu Apr 25 2024

Going forecast on track. No changes planned.

SHORT TERM
(Friday through Saturday night)
Issued at 220 PM EDT Thu Apr 25 2024

A stalled and diffuse boundary near the FL/GA border will begin to dissipate through Friday as high pressure shifts to the northeast and wedges across the local area. This will increase the local gradients and onshore flow through Saturday. Through Saturday, ridging will aloft will amplify along the eastern US. Subsidence associated with this feature will keep meaningful rain chances near nil; however, a weak coastal trough over the local waters may push a few sprinkles into the immediate coast on Saturday (kept pops silent <10% at this time). With the moistening onshore flow, skies will trend partly to mostly cloudy by Saturday, especially near the coast. Combination of increasing cloud cover and the breezy, 10-15 mph, onshore flow, temps will trend from the mid 80s inland Friday to the low 80s Saturday while the coastal areas peak in the upper 70s to near 80 each day while overnight temps remain in the mild low/mid 60s.

The main concern over the weekends will be beach hazards as surf builds and rip current risk increases (more below in the marine section).

LONG TERM
(Sunday through next Thursday)
Issued at 220 PM EDT Thu Apr 25 2024

Ridging progged to initially hold steady through the end of the weekend and into early next before being flattened by a dampening upstream shortwave trough Tuesday. That feature will drag a surface cold front with it but as it weakens the front appears to stall generally to the northwest, extending the ongoing dry-spell likely through the latter end of next week when sea breeze showers may begin to be prevalent... Otherwise temperatures will trend above normal through next week with temperatures flirting with the 90s once again as southerly flow develops.

MARINE
Issued at 220 PM EDT Thu Apr 25 2024

A weak cold front has stalled across the FL/GA line, increasing cloud cover for SE GA. Weakening high pressure to the south has allowed the Atlantic sea breeze to develop near shore this afternoon and evening. Onshore flow will strengthen Friday and through the weekend creating cautionary conditions for NE FL near shore waters over the weekend and possible small craft advisory conditions offshore as seas build for NE FL Saturday evening and into early Sunday morning.

Rip Currents: Moderate Rip current risk at all beaches today, increasing to high risk by Saturday morning and lasting through the weekend as surf builds around 5 foot and breezy, persistent onshore winds develop.

FIRE WEATHER
Issued at 220 PM EDT Thu Apr 25 2024

A weak cool front will near the FL/GA border will dissipate through Friday as strengthening high pressure wedges in from the northeast.
This will lead to increasing easterly surface and transport winds Friday and into the weekend yielding elevated to high dispersions, particularly Saturday. Given the onshore flow, afternoon humidity will gradually trend upward each day. However, winds will be elevated (10-15 mph) and a bit gusty during the afternoons (15-20 mph) through the weekend as well.
