For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

A few light showers continue to move south along the coast from near Fernandina beach towards Mayport and Ponte Vedra Beach with low stratus advecting in from the north on the back side of a weak low pinwheeling northeast of the Georgia waters that pushed a cold front south of the area overnight. Low clouds are keeping our temperatures in the upper 60s to lower 70s which should cool only a couple more degrees as dewpoints hold in the mid 60s inland to upper 60s at the coast.

A "Z" like pattern in the mid to upper levels over the eastern third of the country will promote ridging over the Mid Atlantic and northeast states today while a short, compact trough will elongate over the western Atlantic waters west of Bermuda. High pressure will build from the Mid Atlantic coast as surface low offshore spins slowly away to the east. Drier air aloft will sink across the area with isolated to widely scattered showers shifting south and west from the Jacksonville Metro area this morning into interior NE FL midday and then north central FL this afternoon with an isolated thunderstorm possible south of I-10, but not expecting strong or severe storms due to influence of the drier, cooler airmass that will limit high temperatures to the low 80s along the coast and mid 80s inland. Mostly clouds skies and low stratus east of highway 301 this morning will turn partly cloudy this afternoon, then skies will become clear around sunset from north to south with breezy northeast winds 10-15 mph and gusting to 25 mph over the coastal communities. With clear skies tonight, lows will be near normal in the low to mid 60s with upper 60s to around 70 at the beachfront.

SHORT TERM
(Tuesday through Wednesday night)
Issued at 317 AM EDT Mon May 20 2024

Onshore flow pattern could support a few coastal showers expanding inland over ne FL during the afternoon. By Wed, upper ridging builds over forecast area supporting a drier pattern across forecast area and initiating a warming trend. High temperatures will be in the 80-85 range across the forecast area Tuesday, warmer values interior areas, and will rise to the lower-mid 80s east, upper 80s west, on Wednesday.

LONG TERM
(Thursday through Sunday)
Issued at 317 AM EDT Mon May 20 2024

Upper ridge of high pressure will remain over the forecast area through Friday, with a continued warming trend. High temperatures Thursday and Friday will be in the mid-upper 80s coast, lower-mid 90s well inland, a little above normal.

A weak shortwave trough will move across GA and the Carolinas Saturday which could bring scattered showers and a few t-storms across the area, with a slightly better chance N than S. By Sunday, a few sea breeze showers/t-storms are possible during the afternoon. The weekend will feature somewhat above normal temperatures, with high temperatures both days in the upper 80s immediate coast, lower 90s further inland, with mid 90s possible in a few areas.

AVIATION
(06Z TAFS)
Issued at 156 AM EDT Mon May 20 2024

MVFR/IFR low ceilings are sinking south along the coast from SSI to the duval county TAF sites and should sink towards SGJ over the next hour, but remain northeast of GNV as weak high pressure builds to the north as the low to the northeast shifts east of the South Carolina coast. Light northerly winds 4-8 knots will become more northeasterly towards 10Z and breezy at SSI through sunrise as the high builds down the east coast with continued MVFR ceilings and occasional IFR ceilings for most sites except GNV through 13Z with MVFR ceilings rising to 2.5 kft through 15-17Z along the coast while lifting to VFR inland after 13Z.

Monday will feature breezy conditions 10-15 knots with gusts with higher gusts 20-25 knots near the coastal sites and 15-20 inland.
Widely scattered showers and thunderstorms possible inland where greater heating develops as drier air aloft shifts south across area, limiting shower development for SSI and ending VCSH coverage at JAX/CRG by 17Z/18Z with lingering convection over inland Northeast Florida by 22Z. Skies will clear from the northeast by the end of the TAF period.

MARINE
Issued at 317 AM EDT Mon May 20 2024

High pressure will build along the Mid Atlantic coast today into Tuesday with breezy onshore northeasterly flow. High pressure will then build directly over the waters Wednesday through the end of the week with east to southeasterly winds as the Atlantic seabreeze develops each afternoon.

Rip Currents: Moderate risk of rip currents at all area beaches today in the onshore northeast flow. A moderate risk expected on Tuesday for all area beaches.
