NEAR TERM
Issued at 238 PM EDT Tue Apr 23 2024

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

Under high pressure ridge, mainly clear skies will continue through the night, with lows falling into the lower to mid 50s.

SHORT TERM
(Wednesday through Thursday night)
Issued at 238 PM EDT Tue Apr 23 2024

Wednesday...Weak cold front pushes through the SE US states and reaches Central GA/Carolinas by the end of the day but remains void of any measurable rainfall at this time. The West to Southwest steering flow will push temps back closer to normal values with highs in the 80-85 range over inland areas and in the upper 70s along the coast.

Wednesday Night...The weak frontal boundary will sag further south through SE GA and end up near the FL/GA border by early Thursday morning, but still not expecting any measurable rainfall at this time, but some slight increase in cloudiness is expected across SE GA while NE FL remains mostly clear. Seasonably cool overnight lows in the 50s will continue over inland areas, with lows near 60 along the coast. Some patchy fog possible along the I-75 corridor of inland NE FL by sunrise Thursday morning, but air mass remains too dry for any significant fog at this time.

Thursday...The weak frontal boundary across the NE FL/SE GA region will become diffuse and still expect mainly dry conditions, but enough increase in moisture and diurnal heating into the middle 80s over inland areas and sea breeze boundaries might be enough to trigger an isolated afternoon shower, but overall measurable rainfall chances remain less than 20 percent.

Thursday Night...High pressure builds to the NE of the region over the Carolinas and this will increase low level easterly/onshore flow along with some increase in cloud cover over the Atlantic Coastal waters and closer to the old frontal boundary across SE GA, and again only limited/isolated shower activity is expected over the Coastal waters, mainly near the better low level convergence along the SE GA coastal areas. Overnight lows a bit milder around 60 over inland areas and near 65 along the Atlantic Coast.

LONG TERM
(Friday through next Tuesday)
Issued at 238 PM EDT Tue Apr 23 2024

Rather stagnant pattern will remain in place through the period with high pressure ridge axis remains oriented East to West across the Carolinas, which will continue a breezy Easterly/Onshore flow across the region through the weekend, which will slowly become more Southeast early next week as long range models suggest this high pressure ridge axis will drift slowly southward through the period. Rainfall chances will remain limited through the period with only a few isolated showers over the Coastal waters, or possible along the East Coast sea breeze as it pushes inland each day, but again overall measurable rainfall chances remain at 20 percent or less through the period. Temps will be close to normal values through the weekend with a trend towards above normal temps early next week as the ridge axis slides southward. These high temps will generally be in the mid/upper 80s over far inland areas, with lower 80s along the I-95 corridor and around 80 each day along the Atlantic Coastal areas.

AVIATION
(00Z TAFS)
Issued at 737 PM EDT Tue Apr 23 2024

High pressure will continue mostly VFR conditions and dry weather through the end of the 00Z TAF period. Clear skies and light east winds overnight will turn variable at the coast 3 to 5 knots while calm inland by 02Z. Continued low end MVFR potential for VQQ late 08Z-11Z. Sunny skies prevail into the early part of Wednesday with Atlantic seabreeze moving onshore SGJ/SSI by 16Z/17Z and onto CRG and JAX by 18Z and 20Z with southeast winds around 10 knots along the coast inland stays south southwesterly 5-7 knots. Few clouds will develop around 5.0 kft over the Northeast Florida sites by afternoon and a perhaps a few wispy cirrus clouds.

MARINE
Issued at 238 PM EDT Tue Apr 23 2024

High pressure ridge will be across the area through Tonight, then slide to the south Wednesday. A weak cold front will move south into region Thursday and stall. High pressure will build to the northeast late in the week through the weekend.

Rip Currents: SE GA Moderate through Wednesday NE FL High Today, Moderate Wednesday

FIRE WEATHER
Issued at 238 PM EDT Tue Apr 23 2024

High pressure and dry air mass will remain in place on Wednesday, then a weak frontal boundary will sag southward into SE GA Wednesday Night and stall near the FL/GA border on Thursday before washing out. High pressure will re-build north of the region on Friday with a breezy Easterly/Onshore flow expected through the weekend. Near critical humidities falling to around 30 percent are expected Wednesday afternoon, but winds will remain around 10 mph or less. Minimum humidities will be closer to 35 percent on Thursday afternoon with light and variable winds. The East Coast sea breeze will remain pinned closer to the coast along the I-95 corridor on Wednesday afternoon, but will move further inland to the US 301 corridor on Thursday afternoon.

Patchy fog will be possible over inland areas the next couple of mornings, but significant fog is not expected.
