NEAR TERM
Issued at 259 AM EDT Fri Apr 19 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

High pressure east of the area will dominate the local weather pattern today and tonight with just some high cirrus across the region. High temperatures will generally be in the lower 90s except in the upper 70s to lower 80s along the coast as a sea breeze develops this afternoon. Overnight temperatures will be in the lower to mid 60s inland and in the mid to upper 60s for the beaches.

SHORT TERM
(Saturday through Sunday night)
Issued at 259 AM EDT Fri Apr 19 2024

A cold front will slowly sink southward into Georgia on Saturday, prompting scattered showers and embedded isolated thunderstorms across southeast Georgia. By Sunday, the front will be lingering near the Florida/Georgia state border, allowing for precipitation potential to spread southward through the Gainesville/St.
Augustine line. Again, scattered thunderstorms will be likely throughout the day Sunday, and through the overnight hours area- wide.

Temperatures will be well above normal this weekend, with SE GA and NE FL seeing high temperatures in the upper 80s to lower 90s Saturday, including beach side due to southerly winds. Sunday will be a few degrees cooler, with highs in the mid to upper 80s across NE FL, and upper 70s to mid 80s across SE GA depending on the front's position.

LONG TERM
(Monday through Thursday)
Issued at 259 AM EDT Fri Apr 19 2024

By Monday, the front will be south of the area, leaving the rest of the week dry as high pressure builds behind the front. As the front passes through on Monday, scattered showers and thunderstorms will be likely area-wide, along with below normal temperatures for most of the region. Highs in SE GA will stay in the upper 60s to lower 70s, with high temperatures in the 70s across NE FL. Each day of the week will get gradually warmer, by Wednesday highs will be in the 80s area-wide.

AVIATION
(12Z TAFS)
Issued at 732 AM EDT Fri Apr 19 2024

Localized low stratus pushing from the Gulf of Mexico will advect over GNV and lead to LIFR/IFR ceiling through around 13z. Elsewhere, VFR conditions will prevail as layered mid and high cloud trail west to east. Westerly winds will be favored this morning at or below 10 knots at all sites. The afternoon sea breeze will shift winds to ESE as it begins to push inland around 19/20z and reaching the I-95 corridor around 22z where it will dissipate this evening.

Tonight, VFR conditions will persist at airfields along the I-95 corridor whereas low stratus and fog (IFR/LIFR) will advance from the Gulf toward the I-75 corridor during the predawn hours Friday, impacting GNV and possibly VQQ. It doesn't appear this layer of low stratus will push to the I-95 corridor at this time.



MARINE
